PTFE Parts
As a Teflon washers manufacturer, Bueno Group provides various PTFE parts for ball valves, such as washers, gasket, machined parts, cavity filler seat, ball valve seats, convoluted hose, etc.
- PTFE seats, inserts, and sealing parts for ball valves, threaded valves, flange ball valves, clean valves, etc.
- Maximal outer dimension: 1300 mm.
Valve seats offer a tight seal when the valve closes. To endure the repetitive motion, the valve seat must be wear-resistant. The other function of the seat is to dampen the shock when the valve closes frequently. With the seat serving as the cushion, it mitigates the possible damage and prolongs the service life of the valve. Valve seats, washers, gaskets, etc. are an essential factor in the performance of the valve unit and fluid control systems yet their importance is often neglected. Bueno understands the importance of these components. We are a professional Manufacturer of Teflon® washers, Teflon® parts, and Teflon® gasket material.
What is PTFE?
PTFE stands for polytetrafluoroethylene. It’s a chemical term for the polymer (C2F4)n. PTFE is one of the thermoplastics from the fluoropolymer family and has a low friction coefficient, excellent antistick properties, and excellent insulating properties. It is chemically inert and can withstand high heat, which allows the material for a wide range of applications. Click here to learn more! It is crucial to choose the sealing part with the right material for your valve unit. Bueno provides OEM custom services. The PTFE materials Bueno processes are listed as follows:
