Piston Valves - Stainless Steel Gland-less Isolation Design | Class Vi Leak-proof Sealing, Self-cleaning, On-line Maintenance

In sequence to cater customer demand on a proper time, we are indulged in exporting, manufacturing and supplying of Piston Valves in Pune Cantonment, Maharashtra, India. Energy Audits carried out by us at a large number of process plants reveal that in a typical 5 years old plant, over 30% of isolation valves leak. Valve glands and seats are the typical locations where leaking initiates. Forbes Marshall piston valves are gland-less isolation valves which offer leak-proof sealing. A burnished piston seals against SS reinforced graphite rings to achieve a leak proof class VI shutoff. This unique design ensures a long life even at high temperatures up to 427 Deg. C.

Features:
1. Larger effective sealing area, 480% more than a globe valve
2. Self-cleaning and self-lubricating
3. Absence of Gland and Seat. Does not need piston valve key
4. Maintenance friendly - Uniform sealing rings on both the sides and maintenance can be done without removing the Piston Valve from the pipe line. (On-line Maintenance)
5. Asbestos free manufacturing

Benefits:
1. Forbes Marshall piston valves use one type of sealing ring to suit all applications, which reduces the inventory of spares
2. Provide Class VI shut-off and ensure zero inline leakage.
3. Verstalie and can be used for multiple fluids without any special adaptations.
4. Long life and maintenance free for lowest cost of ownership.
