   Piston Valve

Special Features:
Marck 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 Marck 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 427 oC 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, Marck Piston valve is the right solution for on-off operation not only for STEAM but also for THERMIC FLUIDS, AMMONIA, LPG, ACIDS, ALKALIS etc
