HTS single seat control valve is a top-guiding structure of the control valve. The valve body fluid channel is S-streamlined, with small pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow characteristic curve, large guide area of the valve core and good vibration resistance. The control valve is equipped with multi-spring film actuator, which has compact structure and large output force. It can be used to control fluids of various pressures and temperatures.
