Product Description:
ZXPD Pneumatic Membrane Cryogenic Angular Control Valve is a kind of control valve used in low temperature and cryogenic occasions. It adopts long neck valve cover insulation and is equipped with a multi-spring execution structure, which has the advantages of compact overall structure, light weight and good stability. The valve body adopts a precision cast angular structure, and the material is aluminum alloy, which has good low temperature resistance. The bellows seal ensures that the control valve does not leak out at low temperatures. Therefore, it is widely used in metallurgy, air separation, oxygen production, petroleum, chemical industry and other low-temperature and cryogenic occasions. It is especially suitable for precisely controlling the process parameters of cryogenic gases, fluids (such as liquid oxygen, liquid argon, etc.) to maintain the given value.
This series of products has two types of connecting plate mounted type and floating sleeve mounted type, the nominal pressure level is PN0.6MPa, the valve body diameter range is DN20~100, the applicable fluid temperature is -60°C~-250°C range of various grades, the leakage volume level is IV and VI two, and the flow characteristics are linear or equal percentage. A wide variety of varieties and specifications are available.
Product Features:
The bottom is in and out of the side, the flow path is simple, the resistance is small, and the valve body capacity is large
Double guide, good valve working stability
The adjustable range is large, and the intrinsic adjustable ratio is 50
Bellows seals form a complete seal on the moving stem and prevent fluid leakage
It is connected with a floating sleeve for easy installation
Floating sleeve mounted type
Warm jacket is used when the fluid is easy to crystallize and solidify after cooling, causing blockage.
