Cla-Val Pressure Sustaining/Relief Valves - Series 50

Distributed by Devine & Associates Ltd.
Brand: Cla-Val

Diaphram actuated globe-style valves are used to regulate upstream pressures. Models include 50-01 full-port valves, 650-01 reduced port valves. Sizes range from 1 1/4" to 36" and larger.
Cla-Val pressure relief/sustaining/backpressure valves are hydraulically operated, pilot-controlled, modulating valves designed to maintain constant upstream pressure within close limits. These valves can be used for pressure relief, pressure sustaining, back pressure, or unloading functions in a by-pass system.
These valves are actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. Operation is completely automatic and pressure settings may be easily changed over a wide range. Many types, options and materials available. Additional services provided.
