Description

A rubber flapper foot valve consists of a valve body, a cover, feet, and a flapper that is connected to the body and cover. The flapper swings away from the valve seat to allow flow in the forward direction, and returns to the valve seat when upstream flow is stopped to prevent backflow. They can be equipped with optional strainer attachment in place of the feet.

Handling and Storage

Lifting the valve improperly may damage it. Do not fasten lifting devices to the actuator or through the seat opening in the body. Lift the valve with slings, chains or cables fastened around the valve body, or fastened to bolts or rods through bolt holes in the flanges.

If installation will be delayed, place valve indoors in secure, weather tight storage. If temporary outside storage is unavoidable, make sure a vermin proof rain cover (water shedding tarp, etc.) is secured around/over the equipment to keep off rain and mud. Skid and set the assembly on a flat, solid, and well drained surface for protection from ground moisture, runoff and pooled rain water.

Installation

The APCO FRF Full Flow Rubber Flapper Foot Valve must be installed in the vertical position (with the flow upward). The embossed flow arrow on the valve body must be pointing in the direction of flow.

1. Before installation, remove foreign material such as weld spatter, oil, grease, and dirt from the pipeline.

2. Prepare pipe ends and install valves in accordance with the pipe manufacture’s instructions for the joint used.

Do not deflect the pipe-valve joint. Minimize bending stresses in the valve end connection with pipe loading.

If excessive seat leakage occurs during start-up, recheck the installation and eliminate any distortion to the valve body.

3. Ensure the valve and pipeline flanges are concentric to ensure proper flange sealing and seat leakage control.

4. Tighten the flange bolts or studs in a crisscross pattern and minimum of four stages.

5. It is recommended to manually fill the suction line with water. This eliminates the risk of damage to the pump from running dry.

Fusion/Powder Coated Valves

Valves with fusion/powder coated exterior paint require flat washers to be installed under the flange nuts when installing the valve to the pipeline flange to prevent the paint from cracking or chipping.

Maintenance

The FRF Full Flow Rubber Flapper Foot Valve does not require routine maintenance, but should be included as part of the normal facility equipment inspections for any malfunction while under normal usage conditions. An inspection can be quickly performed as follows:

Servicing the valve while the pipeline is under pressure can cause personal injury or equipment damage. Relieve pipeline pressure before servicing the valve.

1.

Relieve the pressure in the pipeline.

2.

Due to the weight of the cover and flapper, it is recommended that 8”+ valves be removed from the vertical position for maintenance.

3.

Isolate the Rubber Flapper Check Valve from system before loosening the Cover Bolts (4) to remove the Cover (2).

4.

Loosen each cover bolt only three full turns, then tap the side of the cover with a mallet to separate only the valve cover from the Cover Gasket (3), this will relieve any pressure in the valve.

5.

Continue loosening to remove all cover bolts and lift off the cover. After removing the cover, the

Flapper (10) will be fully exposed and freely removed. At this point, the flapper and body surfaces should be examined for wear.

6.

To reassemble, replace Cover Gasket (3), often the same cover gasket can be reused several times.

7.

Replace flapper and be sure it rests flat and centered against the body seat surfaces.

Maintenance (Continued)

8.

Carefully replace cover over the flapper so as not to move the flapper from its seating position, then replace cover bolts and tighten lightly while alternating the tightening of each cover bolt

180° apart to prevent tilting the cover.

9.

It is recommended to manually fill the suction line with water. This eliminates the risk of damage to the pump from running dry.

10.

Slowly open discharge isolation valve to pressurize rubber flapper check valve and observe the cover gasket (3) joint is not leaking.

Operation

The flow from the pump opens the flapper. When the pump is shut off, backflow pressure pushes the flapper to close against the body seat surface. The feet allow the valve to sit on the bottom of the wet well. The strainer option helps filter out any large debris.

Troubleshooting

Condition

Cover leaks.

Valve leaks excessively from one side of the flapper to the other.

Possible Cause

Cover gasket is damaged.

Foreign matter caught between flapper and seat.

Flapper is worn or damaged.

Corrective Action

Replace cover gasket.

Fully open valve to remove object.

Replace flapper.

Loose flange bolting. Tighten flange bolting.

Valve leaks at flange joint.

Valve does not fully close.

Blown flange gasket.

Misalignment or damage to field piping and supports.

Damaged flange face/s or improper flange connections.

Object is wedged between seat and disc.

Replace flange gasket.

Adjust misalignment or repair piping or supports.

Repair flange, replace valve body or adjust flange connections.

Fully open valve to remove object.
