Description

Bermad WW-730-X Sigma EN ES Pressure Sustaining Valve

The Bermad 730-X Pressure relief/sustaining hydraulically operated control valve that can fulfill either of two separate functions: When installed in-line, it sustains minimum pre-set, upstream (back) pressure, regardless of fluctuating flow or varying downstream pressure.

When installed as a circulation valve, it relieves excessive line pressure when above maximum pre-set. This valve is a double chamber configuration using 3-way control, being extremely responsive regardless of operating conditions, allowing full opening without the risk of hydraulic lock out.

The double chamber design also ensures the valve acts like a check valve preventing reverse flow.
