SLPV25

Piston Valve is basically Seat less and Glandless valve and by virtue of its design can replace both, the conventional type of Gate and Globe valves, with distinct advantages over them. SteamLok make Piston valve are designed with a unique solid nonmetallic hand wheel. This ensures hand wheel does not get hot and also ‘F’ key cannot be inserted. Piston valve have sealing stacks which are made of alternate Graphite and stainless steel mesh. This mesh helps in bonding both the top and bottom of graphite rings mechanically. This ensure that the stacks are much harder anddo notpeel off.This results in longer life of piston valve. Piston valve have internals, which are burnished to a very high surface finish (0.2 Ra). This ensures thevalves adhere to Class VI leakage.

• Heat resistant hand wheel.

• Wear and Erosion resistant for most of the fluids.

• Unique sealing arrangement for extended life of valve.

• Class VI leakage Valve.

• Use of Belleville washer to compensate thermal expansion.

• It is mainly used for steam and thermal oil isolation purpose.

• Soft Seated Valves Fall Under Class VI

• Does Not Get Affected By Foreign Matter.

• Unique Design Of Piston & Lantern Bush Can Provide Good Regulation With Linear Characteristics
