Product Description

FM PISTON VALVE is a zero leak isolation Piston Valve, in which the seat & gland are replaced by Lower & Upper Sealing rings along with a Piston. This overcomes the difficulties usually associated with the replacement of conventional seats.

The FM Piston valve is the name for prevention of inline leakage as well as leakage through glands, making for leakproof isolation in the pipelines.

The FM Piston valve is a seat less & gland less Piston Valve. At the heart of the FM piston valve are Piston & sealing rings. A burnished piston seals against SS reinforced graphite rings to achieve a leak proof shutoff. This unique design ensures a long life even at high temperatures up to 427 deg C

A Burnished piston is connected to the Piston Valve stem & hand wheel. The piston passes through two sealing rings separated by a lantern bush. Each sealing ring is Stainless steel reinforced graphite, which has both features of sustaining compression exerted by Bonnet & providing soft seal against piston. The upper sealing ring acts as a conventional gland packing and prevents leakage towards atmosphere. The lower sealing ring acts as the seat which prevents in line leakage. The lantern bush is required to maintain separation between the upper & lower rings & to allow flow through the Piston Valve.


FEATURES :
Larger effective sealing area :
  • Leak proof isolation - Class 6 shut off achieved.
  • Durability - Piston unexposed to media
  • Absence of Gland & Seat
  • 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)
  • User Friendly - It does not need Piston Valve Key
  • The Only Scrap Free Piston Valve
  • Self Lubricating
  • Self Cleaning


RANGES :
  • FORGED CARBON STEEL (A105) WITH SS INTERNALS
  • 15 NB, 20 NB, 25 NB, 32 NB, 40 NB in socket weld ends as well as Screwed BSPT /NPT Ends
  • For socket weld ends,
  • Max Operating Pressure : 78 kg/cm2
  • Max Operating Temperature : 427 deg. C
  • Cold Hydraulic test pressure : 156 kg/cm2
  • For Screwed Ends,
  • Max Operating Pressure : 31.64 kg/cm2
  • Max Operating Temperature : 427 deg C
  • Cold Hydraulic test pressure : 63 kg/cm2

CAST CARBON STEEL (ASTM A 216 WCB ) WITH SS INTERNALS
50 NB, 65NB, 80 NB, 100 NB, 125 NB, 150 NB, 200 NB in Flanged ends with ANSI CL.300,
Body design conditions : 42 kg/cm2 at 427 deg C
Max working conditions :39.5 kg/cm3 at 300 deg C
Cold Hydraulic test pressure : 79 kg/cm2
PISTON VALVE STANDARD

ANSI B 16.34 , API 598, API 602 ,IBR / N IBR

APPLICATIONS

Thus FM Piston valve is the right solution for on-off duties not only for STEAM but also for LPG, AMMONIA, ACIDS, ALKALIES & THERMIC FLUIDS.

Advantages

FM PISTON VALVE is energy saving isolation valve, preventing above all types of valve leakages & increasing the life of the valve. It is gland less & Seat less, so it gives relief from the problems associated with seat & gland packings.

The Heart of the FM piston valve is Piston & sealing rings. A burnished piston against Stainless steel reinforced graphite rings gives leak proof shutoff , which ensures long life even at high temperatures up to 427oC

Piston valve is operative friendly, means with little amount of effort , valve can be operated. It eliminates the need for any valve key to tighten the valve.

Maintenance can be done easily & quickly i. e. internals can be removed without removing the valve body from the main line. This minimizes the plant downtime

In this way , FM Piston valve is the right solution for on-off operation not only for STEAM but also for THERMIC FLUIDS, AMMONIA, LPG, ACIDS, ALKALIS etc..
