Hydraulic Drive Diaphragm Control Valve, Plastic, DN50-DN100

Key Specifications / Features

The Hydraulic Drive Diaphragm Control Valve Factory produces a specialized filter backwash hydraulic valve designed for efficient water treatment applications. This valve features a durable plastic body, available in sizes ranging from DN50 to DN100. It offers a maximum flow rate of 80 cubic meters per hour and operates within a pressure range of 0.7 to 10 bar. This valve is ideal for filtration systems requiring reliable backwash control.

The Filter Backwash Hydraulic Valve is a compact, T-shaped 3-port valve featuring a double-chamber, hydraulically operated, diaphragm-actuated design. It can be paired with a gravel filter or disc filter to form an automatic backwash filtration system, or used in water supply lines to change the flow direction. The valve’s two control chambers allow conversion between angular and straight flow by altering the spring assembly orientation. Its unique cavity design ensures a high water flow capacity, making it suitable for both automated back-flushing filtration and water supply rerouting applications.
