Zjhp/m-Gw Pneumatic Control Valve

ZJHP/M-DW Pneumatic cryogenic control valve is one of the pneumatic control valve products developed by our company specifically for ultralow temperature conditions.Pneumatic cryogenic control valve has been widely used in the automatic control of industrial processes such as petroleum, chemical industry and metallurgy. Pneumatic cryogenic control valve is especially suitable for the regulation of medium (such as liquid oxygen, liquid nitrogen, etc.) at low temperature conditions of -60~-196 °C. To ensure adjustment accuracy, a valve positioner must be used. The ultra-low temperature pneumatic control valve is a deformation product of a single-seat control valve and a double-seat control valve. The difference between the ultra-low temperature pneumatic control valve and the normal temperature control valve is that the long neck type upper valve cover is used to make the packing work at normal temperature. Pneumatic cryogenic control valve is input by the valve positioner to the air pressure of the pneumatic diaphragm actuator to generate thrust. The valve core is driven by the connecting rod. The change of the position of the valve core changes the flow cross-sectional area of the valve to realize the adjustment of the medium flow.

The ZJHP/M pneumatic diaphragm regulating valve consists of a multi-spring pneumatic diaphragm actuator and a low flow resistance fine regulating valve body. The multi-spring actuator is low in height, light in weight and easy to install. The pneumatic diaphragm regulating valve body flow path is S streamlined, which has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, and convenient maintenance. It can be used in demanding working conditions. The pneumatic diaphragm regulating valve is equipped with an electric-gas valve positioning or a pneumatic valve locator, which can realize automatic adjustment control of the fluid medium of the process pipeline. Fine small pneumatic control valve is widely used in precise control of gas, liquid, steam and other media process parameters such as pressure, flow, temperature, liquid level and other parameters to maintain a given value. The precision small pneumatic control valve is especially suitable for occasions where the leakage is small, the pressure difference between the valve is small, and there is a certain viscosity and a small amount of fiber medium

ZJHP pneumatic film single-seat control valve is composed of multi-spring pneumatic diaphragm actuator and low-flow resistance small single-seat control valve body. Pneumatic single-seat control valve has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient maintenance. It can be used in demanding working conditions. The multi-spring actuator is low in height, light in weight and easy to install. The pneumatic single seat control valve is equipped with a valve positioner to convert the current signal into a corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve continuous adjustment of the process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline. Pneumatic film single seat control valve is widely used in precise control of gas, liquid, steam and other media, especially suitable for work situations that allow small pressure difference and allow small leakage. The pneumatic diaphragm single seat control valve is stable in operation with reliable operating characteristics, small valve seat leakage, precise flow characteristics, and wide adjustable range. It will surely achieve high quality control effects in a wide range of applications with its unique advantages
