Pressure reducing valve is an essential component of the pneumatic control valve, the main role is to reduce the pressure of the gas source and stable to a fixed value, in order to facilitate the control valve to obtain a stable gas source power for regulating control. According to the structure, it can be divided into film type, spring film type, piston type, lever type and bellows type. According to the number of seats, it can be single seat type and two seat type; according to the position of the valve, it can be divided into positive action type and reaction type.
HANGONG HTD series universal pressure reducing valve is mainly used in regulator / analyzer and semiconductor industry. Internal thread design to minimize cleaning time, reduce the amount of operation and calibration gas. The base material of HTD conforms to the requirement of medium corrosion and high temperature. Gas management systems, such as gas management (air, clean air and plant nitrogen), are used in process analyzers for petrochemical / refinery and semiconductor processes. HTD is a high pressure relief valve, which provides a variety of options according to the actual situation to meet the design requirements of the system.
