SEMPELL HIGH PRESSURE FORGED GLOBE VALVES

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Before installation these instructions must be fully read and understood

Handling requirements

A - Packed valves

Pallets: Lifting and handling of the packed valves in pallets will be carried out by a fork lift truck, by means of the appropriate fork hitches.

Cases: The lifting of packed valves in cases will be carried out in the lifting points and at the center of gravity position which have been marked. The transportation of all packed material must be carried out safely and following the local safety regulations.

VALVE STORAGE

Preparation and preservation for shipment

All valves are properly packed in order to protect the parts that are subject to deterioration during transportation and storage on site. In particular, the following precautions should be taken:

1. The valves must be packed with the plug in the closed position.

1a. Buttwelding end valves: weld ends surface shall be protected with suitable protective like Deoxaluminite. The ends shall be closed with plywood or plastic discs fixed at the edge by strips.

1b. Flanged end valves: the flange sealing surfaces (raised faces) of the valves shall be protected with suitable protective grease. The end faces of the valve must be protected with plastic or wooden discs fixed with straps.

2. All actuated valves must be securely palleted or crated,with particular attention, in order to ensure that parts of actuator do not extend beyond the packing size.

3. The type of packing must be defined in the

Customer’s order and shall be appropriate to ensure safe transportation to final destination and eventual conservation before installation.

B - Unpacked valves

1. The lifting and the handling of these valves have to be carried out by using appropriate means and by respecting the carrying limits.

The handling must be carried out on pallets, protecting the machined surfaces to avoid any damage.

2. With large dimensions valves, the sling and the hooking of the load must be carried out by using the appropriate tools (brackets, hooks, fasteners, ropes) and load balancing tools in order to prevent them from falling or moving during the lifting and the handling.

Storage and preservation before installation

In case the valves have to be stored before installation, the storage has to be carried out in a controlled way, and has to be performed in accordance with the following criteria:

1. The valves have to be stocked in a closed, clean and dry storage room.

2. The plug must be in the closed position, and the end faces must be protected with plastic or wooden discs fixed with straps.

If possible, keep the original protection.

3. Periodical checks have to be carried out in the storage area to verify that the above mentioned conditions are maintained.

• Do not place consignment packages directly on the ground.

• Do not expose consignment packages to the weather or directly to the sun.

• Check the packaging every two months.

NOTE

Storage in an open area for a limited period can be considered only in case the valves have appropriate packing (packed in cases lined with tarred paper, and contents well protected with barrier sacks).

Caution must be taken during the handling to avoid that this equipment passes over the workers or over any other place where a possible fall could cause damage. In any case, the local safety regulations must be respected.

INSTALLATION

Preparation before Installation

1. Carefully remove the valve from the shipping package (box or pallet) avoiding any damage to the valve or, in case of automated valves, to the electric or pneumatic/ hydraulic actuator or instrumentation.

2. The valves are shipped with the ends protected with caps and a thin layer of protective grease. Before installing the valve, remove the caps and clean carefully, then de-grease both surfaces with a solvent.

Clean the inside of the valve with a clean cloth.

3. Confirm that the materials of construction listed on the valve nameplates (service and temperature) are appropriate for the service intended and are as specified.

4. Define the preferred mounting orientation with respect to the system pressure. If any (see arrow on the body), identify the upstream side and downstream side.

CAUTION

For valve handling and/or lifting, the lifting equipment (fasteners, hooks, etc.) must be sized and selected while taking into account the valve weight indicated in the packing list and/or delivery note. Lifting and handling must be made only by qualified personnel.

Do not use the lifting points located on the actuator, if any, to lift the valve. These lifting points are for the actuator only.

WARNING

See the actuator user manual for the actuator preparation.

SEMPELL HIGH PRESSURE FORGED GLOBE VALVES

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Installation instructions

Globe valves are normally installed in horizontal pipe with vertical stem.

These valves can also be installed in vertical or horizontal pipe with stem other than vertical, but the maintenance is much more difficult.

Globe valves are usually installed on horizontal pipe with the same flow direction of the arrow stamped on the body.

For operating temperatures above 200 °C

(392 °F) a thermal insulation of the valve body is recommended.

Handling and lifting of the valves during installation MUST be performed following the same criteria and instruction described in previous points 'Handling requirements' and

'Storage and preservation' before installation.

WARNING

Before lifting or handling the valve or the valve/ actuator assembly, make sure you have no limitation to do it. Check if there are some safety messages attached to the lifting points of the valve or to the actuator (red rigid label) and, if any, find the proper document in the user manual which describes how you can operate under safety conditions.

A - Buttweld valves

1. Open the valve.

2. Position the valve and check for alignment with the pipe, then proceed with welding, in accordance with the applicable welding procedure.

IMPORTANT

It is recommended to perform piping flushing before installation of valve. If this is not possible, the valves must be set with the plug in full open position before starting with flushing.

Valve verification before start up

1. Tighten the packing just enough to prevent stem leakage. Over-tightening will decrease packing life and increase the operating torque. The bolt torque figures for the packing bolts can be calculated as indicated in Table 1.

2. Check the operation of the valve by stroking it to 'full open' and 'full close'.

3. Should the valve be equipped with electric actuator, please refer to dedicated paragraph (page 4) for actuator adjustment instruction.

IMPORTANT

If piping system is pressurized with water for testing, and in case the piping system has been shut down after testing for a long time, the following recommendations should be adopted.

a. Use corrosion inhibitor with water to pressurize the piping system.

b. After testing, the piping system should be depressurized and the test water completely drained.

WARNING

Before welding, make sure the valve is completely open.

B - Flanged valves

1. Position the valve between the two flanges of the pipe and put the seal gasket between valve flange and pipe flange. Ensure that it is correctly positioned.

2. Assemble the valve to the pipe by means of bolts which shall be tightened by using the crossover method.

3. Progressively reach the requested torque.

WARNING

Verify that the direction of the flow of the line corresponds to the arrow indicated on the valve body. Valves without the arrow are bi-directional.

SEMPELL HIGH PRESSURE FORGED GLOBE VALVES

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Periodic valve verification during service

A - Normal checks

1. Verify every half month that there is no leakage from packing or in the body/bonnet area. If the leakage has been detected from the packing, tighten the gland nuts

(Figure 4, pos. 17) slowly and evenly until the leakage stops, as indicated in Table 1.

If the leakage has been detected from the body/bonnet, tighten the nuts (Figure 4, pos. 10) as indicated in Table 2.

If the leakage does not stop, it is necessary to replace the body/bonnet gasket or to replace the packing.

2. Every 3-6 months, depending on operating frequency, verify the greasing of bearings and the stem thread.

3. For actuated valves, in addition to above, please refer also to the warnings in the actuator manual.

B - Preventive actions

1. Every 6 months verify the tightness of gland bolts.

2. Every 6 months on motorized valves and every 8 months on hand operated valves, grease the stem and the bearings.

3. Every 4 years disassemble the critical service valves and/or actuated valves, verify the seat surfaces and lap them again when necessary. Replace the bonnet gasket and the packing, clean the stem.

4. For the actuator, proceed as indicated in its maintenance manual.

Adjustment of electric actuators

1. For each valve equipped with actuator, a torque calculation has been made.

The size of the actuator is selected on the base of the calculation.

2. The calculated torque is adjusted in the open and close direction on the actuator.

This torque is calculated to suit the valve.

3. Before assembling an actuator to a valve, it is necessary to check:

- The technical data of the actuator.

- The correct adjustment torque.

- The operation instruction.

4. Adjustment of the actuator for GLOBE valves.

WARNING

In the open direction, only the stop has to be set with the limit switch. In case the limit switch is not adjusted, the backseat will be destroyed by the high torque.

In the close direction, the torque switch shall be set.

The adjustment of the limit switches has to be handled when the actuator is assembled to the valve according to the operation instructions.

For this reason note that:

• The calculated torque must be adjusted.

• The closing time must not be too short, because the energy in the close blocked position depends on the actuator speed.

• The test performed without pressure under the piston must be avoided, because the actuator runs with full speed into the seat without any reaction.
