Product Description

HTS Single-seat Control Valve

The HTS single-seat control valve is a control valve with a top-guided structure. The fluid passage of the valve body is in an S - streamline shape, with small pressure drop loss, large flow rate, wide adjustable range, high precision of the flow characteristic curve, large guide area of the valve core, and good anti - vibration performance.

The control valve is equipped with a multi - spring thin - film actuator structure, which is compact in structure and has a large output force. It can be used to control fluids with various different pressures and temperatures.
