HTS single seat pneumatic control valveIt is a type of regulating valve with a top guiding structure. The fluid channel of the valve body is S-shaped, with low pressure drop loss, high flow rate, wide adjustable range, high accuracy of flow characteristic curve, large guiding area of the valve core, and good anti vibration performance. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force. Can be used to control fluids of various pressures and temperatures.
