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.
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
