Low temperature pneumatic control valve

Product Overview

Low temperature pneumatic control valveModel DWZJHP-16P, neck elongation (low temperature -51 ℃~101 ℃) elongation of 130, ultra-low temperature -196 ℃ elongation of 170, diameter DN15-100, pressure PN16-40, material SS304/316, connection method: welding, flange, actuator: multi spring thin film pneumatic actuator.

ZJHPLow temperature pneumatic control valveIt is a top guide structure regulating valve with a compact valve body structure, S-shaped fluid channel, low pressure drop loss, high flow rate, and wide adjustable range. The flow characteristic curve has high accuracy and complies with the IEC534-1-1976 standard. The valve core has a large guiding area, good vibration resistance, and the valve seat leakage meets the ANSIB16.104 standard. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force. It can widely control fluids of various pressures and temperatures.
