Diaphragm valve BC-794-P

hydrauliccontrolshut-off

Hydraulically operated, diaphragm actuated shut-off valve that closes drip tight when inlet pressure rises above a pre-set value. It responds immediately, accurately, and with high repeatability to a rise in system pressure by closing fully and triggering an alarm. BERMAD 700 series valves are hydraulic, oblique pattern, globe valves with double chamber unitized actuator, that can be disassembled from the body as a separate integral unit. The valves hydrodynamic body is designed for unobstructed flow path and provides excellent and highly effective modulation capacity for high differential pressure applications. PRODUCT FEATURES & BENEFITS High Quality Construction Materials – Reliable, resilient and long lasting operation Robust Design – Suitable for constant, intense operation In-Line Serviceable – Quick and easy maintenance and service Line Pressure Driven – Independent operation, no external power needed Unitized Actuator Assembly – Minimal downtime Hydrodynamic Body with Unobstructed Flow Path – Minimal noise and cavitation damage 2-Way Control Loop – Immediate, accurate response to sudden system variations Adjustable Pilot – Easy field pressure setting and calibration Protected Diaphragm – Minimizes chance of damage caused by debris in the pipeline System Failure Indication – Immediate notification to maintenance personnel TYPICAL PRODUCT APPLICATIONS Closes to provide protection from pressure rise due to malfunctioning PRV Provides safety for systems designed with Pressure Reducing Stations featuring redundant branches Where operation of a pressure relief valve must be avoided
