Seat Material of Jacketed Valve

Seat Material of Jacketed Ball Valve

Jacketed Ball valves are used in a wide range of applications.

Various seat materials are available at Switzer Valves Engineering to meet these applications.

• PTFE (Polytetrafluoroethylene)

  PTFE Seats possess high chemical resistance and excellent sealing performance. The ball seats are used in Carbon Steel, Stainless Steel, Bronze, Brass, Cast Iron, Alloy 20 and Duplex Steel Material Jacketed Ball Valves.
  Service Temperature : -100 to +200 Deg. C.
  Working Pressure : 150lb to 300 lb

• GFT (Glass Filled Polytetrafluoroethylene)

  This ball valve seat is made of PTFE reinforced with glass.
  The seat has high mechanical strength, wear resistance, improved hardness, lower thermal expansion, lower deformation under load.
  Service Temperature : -100 to +220 Deg. C.
  Working Pressure : 150lb to 600 lb

• CFT (Carbon Filled Polytetrafluoroethylene)

  This ball valve seat is made of PTFE reinforced with carbon.
  The seat has excellent wear properties against soft metals; high load carrying capability in high speed contact application.
  Service Temperature : -100 to +220 Deg. C.
  Working Pressure : 150lb to 600 lb

• PEEK (polyether-ether-ketone-resin)

  PEEK seats have high mechanical strength at a wide range of temperatures. It also has an excellent resistance to the most critical pressure.
  The seats also have excellent heat and chemical resistance.
  Service Temperature : -100 to +250 Deg. C.
  Working Pressure : 150lb to 2500 lb

• Devlon Seat
  

  DEVLON V-API  is modification of Nylon which is trade name of Devol.
  Devlon Seat have lower water absorption than Nylon, high hardness and high pressure.
  Service Temperature : -100 to +150 Deg. C.
  Working Pressure : 150lb to 1500 lb

• Metal Seat (Hard Faced Metal Seat)

  The surface of the stainless steel seats in hard faced by thermal spraying with nickel and chrome alloys for above 300 Deg. temperature service.
  The seat has high abrasion resistance so that it can handle fluids including foreign particles.
  Service Temperature : -200 to +350 Deg. C.
  Working Pressure : 150lb to 2500 lb
