Description
The Sleeve Type Soft Seat Plug Valve is a high-performance valve designed for reliable cutting and connection of pipeline media across industries such as petroleum, chemical, pharmaceutical, chemical fertilizer, and power. Featuring a bayonet-type tapered plug with self-lubricated PTFE bushings, this valve ensures superior sealing without metal-to-metal contact, minimizing friction and extending service life. Its double-channel groove seal design maintains zero leakage during operation, accommodates thermal expansion, and provides a self-cleaning function for viscous or scaling media. With a compact cavity-free structure, two-way flow capability, and customizable materials and end connections, the valve delivers durability, flexibility, and easy installation under nominal pressures of CLASS150~900LB and temperatures ranging from -29°C to 180°C.
Features
Sleeve type soft sealing plug valve. Bayonet type tapered plug valves are self lubricated PTFE bushing embedded in the body and are pressurized to prevent leakage between the bushing and the body.
Taper plug valves in use of cutting sleeve type has no sealing grease injection may cause pollution, two-way flow, adopting low torque, unique 360° metal lip protection and fixed card sets, make direct contact with no metal to metal seal parts, for taper plug valves of cutting sleeve type has the good seal performance.
Its applicable scope is wide, the friction factor is small, the service life is long, and is the non-metal metal seal, may reduce to the plug processing request, therefore to the small and medium caliber plug valve more generally uses the bush structure form.
- The valve body inlet and outlet end window is designed as a double-channel groove seal ring structure, the plug in the process of rotation, the sealing pressure between the sealing pair in the gradual change, until the full open or closed position, produce enough seal pressure, sealing pair to zero leakage.
- Double channel groove sealing ring can not only make PTFE bushing stable in the valve body does not produce displacement, but also can absorb the microdeformation caused by the change of temperature bushing, at the same time between the bushing and the plug has a strong wiping effect and improve the service life of the sealing surface.
- PTFE bushing, according to the use of temperature and working medium using different materials of filler, good lubrication, long life.
- The sealing of the valve is through the sealing surface around the jacket. Unique 360° metal lip protection fixed card sets.
- The valve has no cavity, the medium is not easy to accumulate.
- The metal lip can provide self-cleaning function when the plug rotates, which is suitable for viscous and easy scaling conditions.
- Two-way flow, more convenient to use and install.
- 8.Material and end connection dimensions of parts can be reasonably selected and matched according to actual working conditions or user requirements to meet various engineering requirements.
