Small Bore Single Seat Control Valve 20mm 25mm ANSI 125 150 300 600
The HLS small-bore single-seat control valve can be used to control fluids with various pressures and temperatures. The valve body has an S-streamline channel, featuring small pressure drop loss, large flow capacity, wide adjustable range, and high flow characteristic accuracy. The control valve is equipped with a multi-spring diaphragm actuator, which has a compact structure and large output force.

Remarks:
1.The maximum allowable pressure difference shall not exceed the maximum working pressure specified in ANSI B16.34
or JIS B2201 standards.
2.In the same cell, the upper value is the allowable pressure difference when the valve is fully open, and the lower value
indicates the allowable pressure difference when the valve is fully closed.
3.For allowable pressure differences marked with *, when the valve controls liquid, the allowable pressure difference shall
be limited to 3 MPa. If it exceeds 3 MPa, please select HLC control valves.
