Ht4000 Series Cryogenic Control Valve For Petrochemical And Metallurgy Industry
Product Description
This series of products has two types: connecting plate installation type and floating sleeve installation type. The nominal pressure level is PN0.6MPa. The valve body diameter range is DN20~100. It is suitable for various grades of fluid temperatures in the range of -60℃~-250℃ and leakage levels. There are two types: IV and VI, and the flow characteristics are linear or equal percentage. A variety of varieties and specifications are available.
Features of pneumatic diaphragm low temperature angle control valve
The pneumatic diaphragm low-temperature angle control valve adopts
a long-neck valve cover for insulation and is equipped with a
multi-spring actuator. It has the advantages of compact overall
structure, light weight, and good stability.
The valve body adopts a precision-cast angular structure and is
made of aluminum alloy, which has good low-temperature resistance.
The bellows seal ensures that the regulating valve does not leak in
low temperature situations.
◆Bottom inlet and side outlet, simple flow path, small resistance,
large valve body capacity, double guide, and good valve working
stability.
◆Large adjustable range, inherent adjustable ratio 50, floating
sleeve connection, easy installation.
