Pneumatic 3-way regulating valve There are two forms of confluence and diversion, which can be widely used instead of two two-way valves and one three-way connection in some occasions.
Pneumatic three-way regulating valve
Realize the adjustment of pressure, flow, temperature, liquid level and other parameters,
The actuator is a membrane type actuator, the valve core adopts a cylindrical thin-walled window, and is guided by the side of the valve core, which has good stability and low noise.
Body form: three-way control valve body; confirm the selected body and trim on the approved drawing
Spool form: three-way double-seat spool
Size: DN20-DN300 NPS 3/4″-12″
Pressure class: PN16-PN100 Class150-600
Connection: Flange, RF/RTJ
Flange distance: according to IEC 60534
Frequently Asked Questions
Do I need a mixing or a diverting configuration?
Show which streams enter and leave the valve and the required operating positions. Request the selected port diagram and flow direction; do not assume a mixing trim and a diverting trim are interchangeable.
What data do you need to select the three-way control valve?
Provide each stream's medium, flow and pressure-temperature conditions, together with the required control duty. Request model-specific sizing and trim confirmation rather than selecting solely from the pipe size.
Will the pneumatic assembly work with my control system?
Specify the available air supply, command and feedback interfaces and required failure response. Ask for the selected actuator, positioner and accessory scope and diagrams before ordering.
