Product Description

This Dual Plate Check Valve that we are offering is extensively used in the fluid processing industry. It is easy to install on the pipeline system as it has a compact and user-friendly design. Owing to its transparent plates you can see the flow of fluids and its processing. Basically, it contains thin stainless steel rings that provide sturdy support to the product and keeps it immune to the abrasive chemical attacks. To meet the diverse requirements for the product, we are offering Dual Plate Check Valve in different sizes and technical specifications.

Valve Feature

The dual Plate Check Valve is an all-purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve. The Dual Plate Check Valve design is the result of attempts to solve the problems associated with swing check valve and lift check valve.The Dual Plate Check Valve employs two spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by torsion spring action without requiring reverse flow. This design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together make the Duals Plate Check Valve one of the most efficient design. It is also referred as SILENT CHECK VALVE. The valve design conforms to APS 594 as well as API 6D except face to face dimensions of ANSI 125 cast iron valves of sizes 65mm (2½”) to 300mm (12” Dual Plat Check Valves are available in wafer design, flanged wafer design and extended design with flanged ends having face to face dimensions as that of a swing check valve.



The valve has cylindrical body which makes the valve look like any other pipe fitting. A cylindrical body has much more uniform distribution of stress compared to a conventional swing check valve. A cylindrical body of the pressure containing part of the Dual Plate Check Valve can be designed to withstand extreme much to the weight (thickness) of valve. Thus for severe/rugged loading conditions, these valves have a distinct edge over the conventional valves both in terms of safety and economics besides general versatility.



The Dual Plate Check valve above 150mm (6”) NB are provided with two springs to avoid disparate forces acting on each plate as in the case of single spring design. This is to ensure even closing. This is achieved single legged or suitably designed double legged springs.



The plate are smaller in area and lighter in weight being two in number compared to one in a conventional swing check valve. The unique feature of plate opening (i.e., it first lifts up at heel and then swings) ensures no rubbing actions against seat. This results in lower rate of wear and tear of seals This feature is not feasible in other designs which results in a higher rate of seal wear. This is achieved

by the special spring action and hinge design.



The installed valve is more rigid than an equivalent length of heavy section pipe eliminating the need for any special support etc. The spring action (in place of gravity) enables the valve to be installed in any position - vertical or horizontal


Typical Applications

The Dual Plate Check Valve is a most versatile design available in specific materials constructions to suit particular Pressure, Temperature and Fluid / Flow Characteristics. Some of the Typical Applications are as follows:

Water :              Water Supply Systems, Fire Water Systems, Cooling Water, Chilled / Hot Water Systems, Boiler Feed Water, Sea Water, Potable Water, Raw Water etc.

Hydrocarbons : All Applications.

Oil & Gas :       Onshore/Offshore, Petroleum, Lubricating Oil, Edible Oils, LPG, LNG, Sour Gas Low Temperature, Cryogenic Applications etc.

Air & Gases :    All gases like Chlorine, Hydrogen, Nitrogen, Carbon Dioxide (Co ), Oxygen etc.

Metallurgical &: Sugar, Pharmaceutical, Paper, Cement, Steel, Aluminium, Copper, Zinc, Power

               and other industries. Chemical processes


There is a solution to almost all NON-Return (Check Valve) problems, varying from Fire Safe Services to Cryogenic conditions, with a suitably designed Dual Plate Check Valve.
