B SERIES VALVES

DESCRIPTION

The Cash Valve Series B pressure reducing and regulating valves are single seated, spring loaded, direct acting diaphragm-type valves that automatically reduce a high initial inlet pressure to a lower delivery pressure and maintain that lower pressure within reasonably close limits.

Exceptionally dependable, Series B regulators are an excellent example of sound engineering and design. They are made of high quality materials to meet the requirements of a variety of applications. Each valve is assembled by skilled workmen and tested before shipment.

Series B regulators are designed and built to withstand long periods of service without maintenance. However, a functioning or operating piece of equipment such as an automatic valve does, in time, require attention.

Simplicity of design aids in the ease of maintenance when repairs may be needed. To keep these regulators in top operating order, Cash Valve make available for the more popular valve models, a convenient, pre-packaged repair kit specifically designed for that particular valve. Each kit includes genuine Cash Valve replacement parts for those that are subject to wear or damage through normal regulator usage.

Every regulator is supplied with the desired delivery pressure pre-set by the factory.

Cash Valve Series B regulators are designed to meet the installation requirements of a variety of systems and are designated as follows:

• Type B - Water and Air Service

(Up to 180°F)

• Type B - Light Oil Service

(Above 180°F)

• Type B - Steam Service

(Up to 400°F)

Simplicity of Design:

The rugged but simple design incorporated in all versions of the Type B regulator lends itself to easy maintenance and repair. Disassembly is simple since there are only six rustproof bolts to remove when replacing diaphragms or pressure springs. The inner valve assembly is easy to clean or replace by just loosening the large hex head bottom plug. All major repairs can normally be made without removing the valve from the line.

Optional Cryogenic Service:

Approved construction is offered for the

Type B regulator to enable it to be used in handling cold fluids or gases. For more information write for Data Sheet

CAVMC-0514.

Inbuilt Strainer Screen:

The working parts of the valve are protected by a self-supporting inbuilt monel strainer screen which is easily removed for cleaning by removing the bottom plug.

Time Tested Rugged Construction:

The Type B regulator has proven itself in countless applications for well over 40 years. The heavy rugged construction ensures long life and service; bodies are of iron or bronze.

The large area reinforced BUNA-N diaphragm is furnished as standard for water or air. These valves are fitted with a carefully matched brass piston and cylinder with a composition seat disc insert for tight shut-off.

Easy Pressure Adjustment:

Pressure adjustment can be changed easily by loosening the lock nut and simply turning the adjusting screw

— clockwise to increase, and counterclockwise to decrease the delivery pressure. The Type B regulator

is furnished with a square head adjusting screw and hex lock nut as standard. They may also be fitted with either a T-handle or an aluminum handwheel for an additional charge.

NOTE: If downstream pressure control is critical to the safety of the installation, then the downstream side should be protected by a safety relief valve set to relieve at the maximum safe limit, but at least 10 psi higher than the delivery setting of the pressure regulator.

Optional Differential Pressure

Control (Type B Steam regulators only):

The Type B Steam regulator can be factory modified to serve as a constant-differential pressure control valve by incorporating a

/

" side tap in the spring housing. In a typical steamoil atomizing installation sketch below, fluid loading pressure is introduced above the diaphragm of the Type B regulator and steam is delivered through the valve at a regulated pressure higher than the loading pressure, with the difference in pressure being determined by the diaphragm

HANDWHEEL

spring setting. The outlet steam pressure is automatically maintained to provide a constant, fixed pressure differential between the steam pressure and the oil pressure. Variations in the loading pressure are reflected in a pound-for-pound change in the discharge pressure.

Valves equipped with the optional differential pressure control are fitted with a pressure-tight closing cap and gasket over the pressure adjusting screw. In addition, a gasket is installed above the diaphragm to ensure a good seal between the spring housing and the valve body.

SPECIFICATIONS (Continued)

The amount of air or fluid any regulator will pass is governed by two factors; (1) pressure differential, or the difference between the inlet and outlet pressure, and (2) a characteristic known as falloff or droop, by which the outlet pressure drops slightly as flow starts through the valve and drops off even more as increased demand requires increased flow. The rates of flow stated on the following charts are based on assumed conditions, which may be considered average for a given installation.

PRESSURE REGULATORS

BBC

HEAVY OIL OR VISCOUS FLUIDS

DESCRIPTION /APPLICATION

Type BBC is a direct acting, single seated, spring loaded diaphragm-type pressure reducing and regulating valve that automatically reduces a high pressure to a lower pressure and maintains the lower pressure within reasonably close limits. It is available in

3

/

8

" through 1

1

/

2

" sizes and may be fitted with either a cast iron or bronze body.

The Type BBC regulator is designed for heavy oil service (Bunker C and other grades), as well as dirty liquids or fluids with a high viscosity. These valves are well suited for systems having a maximum operating temperature of

180°F when fitted with a BUNA-N diaphragm and systems with a maximum operating temperature of

400°F when fitted with a monel metal diaphragm. Type BBC regulators are equipped with a stainless steel piston and seat as standard.

Depending on the setting of the adjusting spring installed, delivery pressures may be adjusted from a minimum of 2 psi to a maximum of

200 psi. The range of adjustment for each of the various springs that may be installed is shown in the Spring Range

Table under Specifications, Page 10.

The table shows the standard factory trim (piston, piston seat, and diaphragm) as well as the inlet pressure maximums for the Type BBC Heavy Oil or Viscous

Fluids regulators. Valves will normally be furnished as indicated, however, other combinations of body material, piston-cylinder and diaphragm are available on special order.

TYPE BBC

The Type BBC Heavy Oil and Viscous

Fluid regulator incorporates a radical departure from the conventional regulator valve design, featuring a

“universal joint” type seating arrangement which insures free valve operation. As a result of this design there are no small ports or close tolerances that would prevent dependable performance. Like other Series B regulators, the working parts are easily accessible without removing the valve from the line. The standard regulator is fitted with a

AMMONIA, GAS OR LIQUID

DESCRIPTION / APPLICATION

Like other Series B regulating valves, the Type BCA is also a direct acting, single seated, spring loaded, diaphragm type pressure reducing and regulating valve that is designed to automatically reduce a high pressure to a lower pressure and maintain that lower pressure within reasonably close limits.

Available in

" sizes with threaded connections, the Type BCA regulator is designed specifically for ammonia service, either gas or liquid.

Fitted with a cast iron body, spring housing, and bottom plug, the Type

BCA regulator is capable of handling inlet pressures to a maximum of 200 psi in ammonia systems having an operating temperature of less than

200°F, and up to 150 psi in systems where the operating temperature ranges from 200°F to 400°F. Inlet pressures may be reduced to a maximum of 125 psi.

Delivery pressures are adjustable from

2 psi to 150 psi depending upon the setting of the adjusting spring installed.

Refer to the Spring Range Table under

Specifications for the adjustment range of each of the various springs that may be installed. The Type BCA Ammonia gas or liquid regulator incorporates a

Monel ® diaphragm, stainless steel piston, seat, piston spring and pusher post button. Both the piston seat and body seat are easily renewable.
