FR Series
Diaphragm Type Valves
Features
■ Protects against periodic high pressures; maintains a desired inlet pressure by relieving to a lower variable pressure, or to atmosphere. Relieves dependably at adjusted pressures; shuts tight after relieving.
■ Features unique “Floating Ring” seating arrangement that produces perfect seat contact.
■ The FR valves afford unusually close regulation, repeatability of opening pressure and close reseating pressures.
■The FR-10 is for more economical, lower pressure applications. (Provided with iron body and spring housing only).

Applications
Cash Valve’s Types FR, FR-6 and FR-10 are fully automatic back pressure valves designed to dependably maintain a pre-determined pressure on the inlet regardless of variations in pressure at the outlet. Excess pressure is relieved into a lower pressure line. Performance is virtually unaffected by pressure variations in the return line. FR Series are continuously operating valves which provide accurate, repetitive, pressure control. FR Series valves are intended for use on practically all fluids and gases except steam.

FRM, FRM-2, FRM-C
| Max Temp. with metal diaphragm: | 500°F |
| Max Temp. with neoprene diaphragm: | 108°F |
| Type FRM & FRM-C Relief pressure range: | 0 - 175 psi |
| Type FRM-2 Relief pressure range: | 0 - 250 psi |
| Type FRM-2 - Sizes: | 1/4'',3/8'', 1/2'' |
| Type FRM & FRM-C Sizes: | 1/8'', 1/4'',3/8'' |
Applications
Cash Valve’s Types FRM, FRM-2 and FRM-C function as automatic pressure limiting regulators, maintaining a desired maximum pressure in system or vessel by relieving excess pressure. The FRM Series Valves are small and compact, yet are highly efficient, making them suitable for numerous applications that call for a small accurate back pressure regulator. FRM Series back pressure valves are intended for service on liquids, air and gases that are not corrosive to bronze.
