Piston Valve

Product Details:

Screwed End Piston Valve are glandless isolation valves which offer leak-proof sealing. A burnished piston seal 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 425 Deg. C.

Features:

• Larger effective sealing area, 480% more than a globe valve
• Self-cleaning and self-lubricating
• The absence of Gland & Seat. Does not need piston valve key
• Maintenance friendly - Uniform sealing rings on both the sides & maintenance can be done without removing the Piston Valve from the pipeline. (On-line Maintenance)
• Asbestos-free manufacturing

 

Benefits:

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

Product Details:

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. The Klinger Piston valve works on the principle of Resilient rings in conjunction with a Metallic Stainless Steel Piston, that moves vertically between the rings, giving a Seal that is both effective as well as Durable. This sealing system gives a bubble tight shut off, equivalent if not superior to Class VI leak standards.The Sealing rings are the heart of the valves, are available in Non-Asbestos, Tanged Graphite, and Graphited Asbestos varieties, to effectively handle more than 250 Industrial Media.

 

Features:

• Economic, easy to service
• Absolutely leak-tight across the ports and to the atmosphere
• No erosion of sealing surface
• Saves energy and does not contaminate the environment
• Maintenance free
• Regulating Piston/Lantern Bush; for coarse regulating/Throttling operation
• Extended Spindle: For Cryogenic application/Hot media to prevent heat transfer to H/W and aid handling of valve
• Heating Jacket: For Media that tends to solidify/crystallize at low temperature and needs constant heating by either steam/Thermic oils circulated through the Jacket.
• Pneumatic, Hydraulic or Electrical Actuator: For remote operating of the Valves
