S220-2-U-1-2-C-B-H-P-12-3 Control Valve

Feature & Principle

It is a spring-diaphragm type pneumatic regulating valve. The air signal acts on the diaphragm to balance the spring force and drive the valve plug to change the flow area. It can stabilize downstream pressure or flow rate automatically when inlet pressure or flow fluctuates. This full model code defines body material, port size, action mode, seal type, mounting and pressure range. It can be matched with positioner for high-precision modulation control.
