API Soft sealing plug valves

API Soft sealing plug valves

Soft sealing plug valves are commonly used in the corrosive, toxic and high against the media, such as harsh environment, a strict ban on the leakage of occasions, as well as the valve material will not form a contaminated medium occasions. Body may be selected in accordance with the work of medium carbon steel, alloy steel and stainless steel materials.
1. It can be used in accordance with the work of medium temperature and the use of F4, F46, PVDF, PP, PO, PE, such as self-lubricating bushing materials, lubrication, and in the process of sealing the entire work of the friction coefficient, Vice small, plug and flexible operation, long service life .
2. Body-side window of import and export of dual-channel design and seal ring groove structure, the process of cocks in rotation, the seal between the sealing vice pressure gradually change, until it reaches the location of full-time or full-clearance, sealed to generate sufficient pressure, zero leakage sealing vice.
3. Dual-channel trench sealing ring can make a solid bushing in the valve body does not produce displacement, can be absorbed as a result of temperature changes in the deformation generated in trace quantities Bushing, Bushing and cocks at the same time have a strong friction between, with automatic cleaning role in enhancing the life of the sealing surface.
4. plunger at the top of a unique anti-lip seal design, the use of a soft sealing material and metal diaphragm and the diaphragm gasket combination of both adjustments can be adjusted between the sealing surface pressure seal so that a flexible plug rotation and to ensure that Progressive export terminal and the sealing flange end connections. 
5. suitable for high-erosion of the gas-solid. Liquid-solid medium. Such as PVC, urea, the anhydride, caustic soda production facilities, or external leakage of high dielectric, such as HF, such as phosgene.
F. may be two-way flow of media, the installation direction of unrestricted online maintenance, the use of more convenient
6. unique design to prevent static electricity, security, fire prevention, the use of safety.
