Bermad WW820 Large Metal Hydraulic High Pressure Reducing Valve

The Bermad WW-820 is a heavy-duty, piston-actuated hydraulic control valve specifically engineered for high-pressure water systems requiring reliable pressure reduction and smooth regulation. Designed to maintain a constant downstream pressure regardless of fluctuating upstream pressure or demand, this valve is ideal for mission-critical applications such as burst protection, noise and flow throttling, and cavitation mitigation.

Featuring a double-chamber body, the WW-820 moderates valve response for stable performance under rapid pressure changes. Its robust internal piston assembly delivers accurate regulation in high-pressure environments, while the V-port throttling plug ensures exceptional stability and control even at low flows.

Built for uncompromising durability, the WW-820 includes a cavitation-resistant stainless steel raised seat, full-bore flow path, and Y- or angle-pattern body for minimal pressure loss and non-turbulent flow. The modular design allows easy servicing and customization with accessories to suit any hydraulic control application.
