In the industrial field, the butterfly valve is a very practical valve, which can easily control and adjust the flow and pressure of various fluid media. However, when we face some special media, such as seawater, acid-base and chemical industries, we need a more powerful valve that can maintain stable and reliable performance in extreme environments. This valve is a stainless steel pneumatic butterfly valve with PTFE seat.

stainless steel pneumatic butterfly valve with PTFE seat

PTFE seat pneumatic butterfly valve is composed of a butterfly plate made of stainless steel and a pneumatic actuator. It uses air pressure to drive the butterfly plate to rotate 90 degrees to realize the switching or adjustment of the medium. There are two types of pneumatic actuators: single-acting and double-acting. Single-acting has an automatic return function and only needs to apply pressure to one air chamber to open or close the valve. Double-acting requires applying pressure to two air chambers to control it. Valve switch. The biggest feature of the PTFE seat stainless steel pneumatic butterfly valve is the use of PTFE (polytetrafluoroethylene) as the valve seat and sealing material, which gives it the following advantages:

  • Corrosion resistance: PTFE is an extremely stable compound, which is hardly attacked by any acid, alkali or organic solvent. This means that the PTFE seated stainless steel pneumatic butterfly valve can adapt to various harsh media such as seawater, acid and alkali, and chemicals without corrosion or leakage.
  • Wear resistance: PTFE has an extremely low coefficient of friction and is one of the solid materials with the smallest friction coefficient known so far. This means that the PTFE seat stainless steel pneumatic butterfly valve has very low wear and torque during the switching process, thus extending the service life and reducing maintenance costs.
  • High temperature resistance: PTFE has excellent high temperature resistance, and its service temperature range can reach -62°F to 500°F (-52°C to 260°C). This means that the PTFE seat stainless steel pneumatic butterfly valve can work normally in high temperature environment without affecting its performance and sealing effect.
  • Self-lubrication: PTFE has good self-lubrication and anti-adhesion properties, which can effectively prevent the medium from scaling or clogging inside the valve. This means that the PTFE Seat Stainless Steel Pneumatic Butterfly Valve can maintain a smooth and clean flow passage, improving flow efficiency and safety.
  • Electrical insulation: PTFE has excellent electrical insulation properties and anti-aging properties, which can ensure long-term stable work. This means that the PTFE seated stainless steel pneumatic butterfly valve can resist electromagnetic interference and environmental changes, keeping the valve precise and reliable.

These advantages make the PTFE seat stainless steel pneumatic butterfly valve the best valve solution for extreme environments such as seawater, acid-base and chemical industries. It can provide zero leakage, high efficiency, safety and reliability, energy saving and environmental protection and many other advantages. If you are looking for such a valve, then VALTECCN is your best choice.
