 Glandless
Piston Valve:
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.
ThePiston valve is the name for prevention of inline leakage
as well as leakage through glands, making for leakproof isolation
in the pipelines.
The Piston valve is a seat less & gland less Piston
Valve. At the heart of the 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

and other presses
- Attemperator application
----------------------------------------------------------------------------------------------------------------------------------------------
Steam Desuperheatering:
The most practical way of reducing the superheat value of
steam is by the direct addition of water. To achieve temperature
stability of the conditioned steam and prevent thermal shock
in downstream pipes, cooling water must be atomized. It is
also necessary to have a correct mix of superheated steam
and cooling water
