Bermad WW-710-B Sigma Double Chambered Large Metal EN ES Powered Hydraulic Solenoid Valve (AS5081 & WaterMark) 

The Bermad WW-710-B is a robust, double-chambered, hydraulically operated control valve that provides powered opening and solenoid-controlled shut-off—making it ideal for systems with very low pressures or corrosive fluids. Designed for use with external fresh water or compressed air, the valve ensures fail-safe performance even under the most demanding operating conditions.

Part of the 700 SIGMA EN/ES Series, this high-performance valve features an oblique globe pattern body with a raised seat and modular double-chamber actuator. The actuator assembly can be removed as a complete unit for fast, easy maintenance. A hydrodynamically designed flow path ensures minimal pressure drop and high flow stability, with V-port throttling for precision control at low flow rates.

Available in Normally Open (NO), Normally Closed (NC), or Latching (LATCH) configurations, the WW-710-B also offers modular upgrade options such as check features, signal feedback, and surge control.
