Product Description
Application
· Complying with GB, ANSI and other standards
· Control valves for process industry and equipment requiring high control accuracy and small leakage, and the applications of high pressure difference and flashing cavitation
· It is widely adopted in the automatic control system of highly toxic, highly corrosive, radioactive and rare precious media in the industries of chemical, petroleum, metallurgy, medicine, electric power, etc.
Features
· Multi-spring pneumatic diaphragm actuator available for selection, simple and firm structure, large output force and long service life
· Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials
· Suitable for various fluids with different pressures and temperatures. S-shaped streamlined channel of valve body, enabling small pressure drop loss, wide adjustable range, high accuracy of flow characteristics, large guide area of valve trim and good vibration resistance
· Optional bellows seal structure adopted for the upper bonnet, eliminating the possibility of medium leakage from the valve stem movement clearance
· For sleeve type, pressure balance structure of valve trim, using small actuator thrust to control the high pressure difference, and a sealing ring between the valve trim and the sleeve to reduce leakage
· For fluorine lined type, tetrafluoroethylene-hexafluoropropylene copolymer (F46), a corrosion-resistant and aging-resistant material, lining at the valve body inner cavity, valve trim, valve stem and other parts in contact with the medium, double seal with PTFE bellows and packing to ensure no leakage
