High pressure differential - high-performance angle control valve

Pneumatic angle control valve with the top of the guide structure, equipped with multi-spring pneumatic actuator. The utility model has the advantages of compact structure, light weight, sensitive action, streamlined fluid channels, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient disassembly and assembly. Widely used in precise control of gas, liquid and other media, process parameters such as pressure, flow, temperature, liquid level at a given value. Especially suitable for small amount of leakage before the valve pressure difference is not large after the high viscosity, containing suspended solids and particulate matter regulation, to avoid coking, clogging, easy self-cleaning and cleaning occasions. This series of products are room temperature type, regulation cut off, bellows sealed, high temperature, thermal insulation jacket and other series. Nominal product pressure rating PN10, 16,25,64,100; body diameter range DN20-DN200. Leakage grade Ⅳ or Ⅵ level. Applicable fluid temperature from -200 ℃ - + 560 ℃ range of a variety of grades, the flow characteristics of linear or equal percentage. A variety of specifications to choose from. This series of control valve structure of new, fully functional, full range.

Note: Normal temperature type: room temperature type operating temperature -20 - +200 ℃, leak level is Ⅳ level. 
 High-temperature bonnet additional heat sink can be used for medium temperature -60- +450 ℃ occasions. 
 Bellows sealed type to move up and down the stem to form a complete seal, blocking fluid leakage. 
 Low-temperature type with extended valve cover and insulation board structure can be -196 ℃ cryogenic occasions.
