Product Description

HLC Small-Bore Cage Single-Seated Control Valve is a high-performance single-seated control valve suitable for high-pressure difference applications where the liquid pressure difference exceeds 3 MPa. The robust valve plug guidance and cage prevent liquid flashing and cavitation. The valve body features an S-streamline channel, ensuring minimal pressure drop loss, large flow capacity, and a wide adjustable range.

The control valve is equipped with a multi-spring diaphragm actuator, which offers a compact structure and high output force.
