shri nath traders has as one of the highly recognized manufacturer & wholesale trader in the industry dealing in products like cast iron fitting products, ductile iron fitting products and many more. The entire product series is highly appreciated by all our customers for their features like effective performance, high strength, sturdiness, and durability and corrosion resistance. Backed by the quality of our product range, these are largely demanded for their used in irrigation, sewage and water supply usages. Owing to our time bound delivery of consignment we have become a preferred choice of our customers and thus have gained huge clients’ base.

 a dual plate check valve is known as butterfly check valve, folding disc check valves, double-disc or split disc check valve. As the name suggests, two halves of the disk move towards centreline with the forward flow and with reverse flow two halves open and rest on the seat to close the flow (flapping action). use of dual plate check valve is popular in low-pressure liquid and gaseous services. Its lightweight and compact construction make it a preferable choice when space and convenience are important. It is 80 to 90% lighter than conventional full body check valve. Frequently used in systems that used butterfly valves. The cost of installation & maintenance is very low compared to other types. a double-disc or wafer check valve consists of two half-circle disks hinged together. The two disks fold together upon positive flow and retract to a full-circle to close against reverse flow. Wafer check valves were designed as a smaller, less expensive option from lift and swing check valves. Wafer check valves are designed to fit between a set of flanges. The disc in disc check valves moves in a plane at right angles to the flow of the fluid, resisted by the spring that is held in place by the retainer. As the upstream pressure increases and overcomes the force of the spring, and the weight of the disc, the disc lifts off its seat allowing flow through the valve. The spring allows the valve to be installed in any direction. These should not be confused with a double check valve, which is an assembly that contains two distinct check valves.

our products are available in isi marked as per your requirement. they are available in different sizes varying from 80mm to 500mm.
