HTS single-seat control valve is a kind of top-oriented structure of the control valve, the valve body fluid channel was S streamlined, the pressure drop loss is small, large flow, adjustable wide range of flow characteristics of high precision curve, the valve guide area, Good sex. Regulating valve with multi-spring film actuator, compact structure, the output force. Can be used to control a variety of different pressures and temperatures of the fluid.
