Bermad WW-710-20 Large Metal Hydraulic Solenoid Controlled Valve with Check Feature (AS5081/WaterMark)

The Bermad WW-710-20 is a robust, hydraulically operated, diaphragm-actuated control valve that opens or closes in response to an electric signal and incorporates an integrated check feature to prevent reverse flow. This double-chambered valve provides precise flow control in complex water networks where non-return functionality and remote actuation are critical.

Designed for network optimization, pressure zone isolation, and flow switching, the WW-710-20 offers a cost-effective alternative to line-sized check valves. It features non-slam closing, low power consumption, and long-term drip-tight sealing, making it ideal for demanding municipal, industrial, or large-scale irrigation systems.

APPLICATIONS

• Zonal return flow prevention
• Burst protection and excess flow shut-off
• Pressure zone isolation and backup
• Automatic reservoir refreshing
• Switching between active system lines (“on-duty” valves)
• Cost-effective replacement for dedicated check valves
