RDDLZ 3 way diaphragm valve is a versatile control valve with three tri clamp ports that can be configured to divert, mix, or isolate fluid flows. Its design includes a diaphragm, a flexible membrane that separates the valve body from the fluid path. The diaphragm is actuated to control the flow direction by either blocking or allowing passage through different ports.

Tips: How does a 3 way diaphragm valve work?

A 3 way diaphragm valve is a control valve with three ports, typically used to regulate fluid flow in complex systems. It operates using a flexible diaphragm that separates the valve body into two chambers. In the default position, the diaphragm blocks the flow between the inlet and one outlet, while the other outlet remains open. When the diaphragm is actuated, it flexes to allow fluid to pass from the inlet to the previously blocked outlet, redirecting the flow. Alternatively, the diaphragm can be positioned to close off the initially open outlet, diverting the flow to the other outlet. This versatile design enables precise control over fluid direction in various applications, making three way diaphragm valves valuable in industries such as pharmaceuticals, biotechnology, and chemical processing.
