3 Way Diaphragm Type Control Valve

ALIS Valves offers 3 Way Diaphragm Type Control Valves designed for precise flow regulation, mixing and diversion of fluids in industrial process systems. These valves feature three ports and a flexible diaphragm that moves in response to an actuator to regulate flow through the valve. Depending on the internal design, they can control the mixing of two incoming fluid streams or divert one incoming stream between two outlets. The diaphragm separates the process fluid from the valve’s operating mechanism, helping reduce leakage paths and supporting reliable control in suitable applications. Depending on the process requirements, these valves can be configured with different body materials, diaphragm materials, pressure ratings, connection types and pneumatic or other compatible actuation systems to achieve the required control performance.

3 Way Diaphragm Type Control Valves are used in chemical processing, water treatment, pharmaceutical production, food and beverage processing and other industrial applications requiring controlled fluid mixing or distribution. Their suitability depends on the process media, diaphragm compatibility, operating pressure, temperature range and required flow characteristics. Important selection factors include valve size, port arrangement, flow capacity, pressure drop, diaphragm material, body construction and actuator requirements. Buyers should confirm whether the application requires mixing or diverting service, as the appropriate flow configuration depends on the valve’s internal design. For automated control, the actuator and control signal must be compatible with the plant’s process control system. Selecting the appropriate 3 way diaphragm type control valve helps provide accurate flow regulation, dependable fluid routing and reliable operation in compatible industrial processes.
