    Pneumatic single seat regulating valve
    Pneumatic single seat regulating valve

    HTS single seat control valve is a top-guided control valve. The fluid passage of the valve body is S streamlined, with small pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow characteristic curve, large valve guide area, and anti-vibration. Sex is good. The regulating valve is equipped with a multi-spring type diaphragm actuator, which has a compact structure and a large output force. Can be used to control a variety of fluids with different pressures and temperatures.
