A piston valve can also refer to a 2-way 2-position, pilot-operated spool valve. The term is extremely popular among spud gun enthusiasts who often build homemade piston valves for use in pneumatic cannon. Valves are typically constructed primarily from pipe fittings and machined plastics or metals. The inside of a piston valve contains a piston that blocks the output when the valve is pressurized, and a volume of air behind the piston. When the pressure behind the piston is released the piston is pushed back by the force of the pressure from the input.

Energy Audits carried out by us at a large number of process plants reveal that in a typical 5 years old plant, over 30% of isolation valves leak. Valve glands and seats are the typical locations where leaking initiates. Forbes Marshall piston valves are glandless isolation valves which offer leak-proof sealing. A burnished piston seals against SS reinforced graphite rings to achieve a leak proof class VI shutoff.


This unique design ensures a long life even at high temperatures up to 425 Deg. C.

Features :

  • Larger effective sealing area, 480% more than a globe valve
  • Self-cleaning and self-lubricating
  • Absence of Gland & Seat. Does not need piston valve key
  • Maintenance friendly - Uniform sealing rings on both the sides & maintenance can be done without removing the Piston Valve from the pipe line. (On-line Maintenance)
  • Asbestos free manufacturing
