About Glandless Piston Valve

Glandless Piston Valve, also called a zero leak isolation Piston Valve, has lower and upper sealing rings with a piston as a replacement of seat and gland. All difficulties linked to the conventional seats replacement are overcome. This valve is suitable option to prevent inline leakage and leakage through glands. It can make for leak-proof isolation in the pipelines.
As it is a seat less and gland less piston valve, there are piston and sealing rings as it's heart. A leak proof shutoff is achieved by sealing of a burnished piston seals against SS reinforced graphite rings. Its design ensures a long life even at temperatures up to 427 degrees Celsius.
There is a piston valve stem and hand wheel connected to a burnished piston. A lantern bush separates two sealing rings between which the piston passes through. These sealing rings are Stainless steel reinforced graphite, featuring sustaining compression exerted by Bonnet & giving soft seal against piston. The upper sealing ring is like a conventional gland packing that prevents the leakage towards atmosphere. The lower sealing ring is like a seat that prevents in line leakage. Both, upper and lower rings are separated with a lantern bush and also allows flow through the Piston Valve.

Features :

Larger and effective sealing area
Durability as the piston is not exposed to media
Self Lubricating and Self Cleaning
No Gland & Seat
Leak proof isolation - Class 6 shut off achieved
Maintenance friendly
Uniform sealing rings on both the sides
User Friendly
It does not need Piston Valve Key
Scrap Free Piston Valve
Process can be executed without removing the Piston Valve from pipeline.

PISTON VALVE STANDARD

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

Applications

The FM Piston valve is perfect for on-off duties for:

Alkalies
Steam
LPG
Acids
Thermic Fluids
Ammonia

Advantages

FM PISTON VALVE is energy saving isolation valve, that prevents all kinds of valve leakages and increases the life of the valve. The gland less & seat less valve is a solution to problems arising from seat & gland packing.
There are piston and sealing rings in the FM piston valve. A burnished piston against SS reinforced graphite rings provides leak proof shutoff, ensuring longer life even at temperatures up to 427 degrees Celsius.
Operation of this valve requires a little effort. There is no need for any valve key to tighten the valve.
Easy and quick maintenance, which minimizes the plant downtime.
