Disc Check Valves from Forbes Marshall are spring loaded, non-return valves which allow flow only in one direction. When fitted at the outlet of traps discharging into closed systems, they prevent the back-flow of discharged condensate into the system. Forbes Marshall spring loaded disc check valves offer a tight shutoff and are available in a large range of sizes. These valves are compact in design as compared to the conventional swing and lift type of disc check valves. They can be easily mounted in between flanges in any direction. These valves are compatible with both PN and ANSI flanges.

Disc Check Valves feature a wafer type, compact and rugged Cast Carbon Steel or Stainless Steel design and are suitable for any process liquid, air, gas, steam etc. The Single Disc Check Valve (Wafer Type Disc Check Valve) consists of four main components: the body, a disc, a star guide and a spring. The Disc check valves are opened by the pressure of fluid and closed through compression spring as soon as flow stops thus preventing reverse flow.

The designing and manufacturing of FLOEC Check Valves Single Disc Spring Loaded Check Valves are done as per DIN 3230. The Valve is designed so as to mount between the Flanges of different standards and in whichever direction as needed. It is very perfect for instrumentation especially for Pneumatic and Vacuum applications as it is offered in both Metal-to-Metal and Soft Sealing alternatives.

R & D Multiple’s Dual Plate Check Valves combine the best features with top class workmanship making them unique for any kind of waterworks applications. The clamped resilient seat on Body is a feature which combines high seal integrity & assurance against seal wash-off. Independent spring action for each plate ensures that the spring twist is half compared to the conventional designs. This greatly enhances the life of the springs. Considering features as above & many others, R & D Multiple’s Dual Plate Check Valves will give you the best in areas of Features, Workmanship, Initial & running costs. This is the best choice. SALIENT FEATURES : Clamped Resilient seal on valve Body. This seal is replaceable on site. Independent spring action for each plate. The pins are precisely & permanently centered in the valve body. The shock dampers ensure that there is no undue load on the Stop Pin & that the spring twist also is maintained in limit. ‘Heeling effect’ for the plates provided to avoid rubbing of the seats near closure.

Spring check valve, This valves, when open, the annular area between the body & plunger available for flow, is equal to the nominal bore area. Therefore, unlike other spring loaded valves & conventional flapcheck valves, these valves offer lower head losses & maintains laminar flow. As the valve closes, due to return spring force, valve is “Quick Closing”. The valve gets closed before the start of back flow return velocity. Hence, water hammer is eliminated in most of the cases.Features: 1.Working principal Hydrodynamic guided closing. 2.The closing mechanism is guided & backed with return spring for quick closing, Opening and perfect sealing. 3.Due to Aerohydro dynamic effect water hammer is eliminated. 4.Very low pressure loss 5.Most suitable for clear liquids & air. 6.Silent operation.
