Overview
HLS small-caliber single-seat control valve can be used to control various pressure and temperature fluids. The valve body is S streamlined channel with small pressure drop loss, large flow, wide adjustable range, high flow characteristic accuracy, and multi-spring type. The film actuator is used together, with compact structure and large output force.
