Check valves are self-activating valves that only let gases and liquids flow in one direction. The use of check valves prevents backflow and maintains pressure. When the system pressure is too high for the primary equipment, they are usually employed as a backup in case a pump fails, to support reciprocating pumps and compressors, and as a backup when a pump fails. In addition to working with water, steam, viscous fluids, and chemicals used in refineries, check valves are utilised in chemical, petrochemical, oilfield, and refining processes. In manufacturing and waste-water treatment systems, check valves are also extensively utilised.
They are referred to as one-way directional valves. In order to prevent backflow, which could result in the pump or compressor cutting off, check valves are widely employed in liquid pumps and gas compressors. They are also utilised in process systems where it is vital to keep various pressures apart. They are self-powered since they rely on the pressure decrease brought on by the medium flow.These valves perform common duties in a more complicated method wherever they are used. In the event of a brake failure, check valves are utilised to stop the flow of gas, fluid, and air. With the help of these self-activating reliant valves, the flow of liquid can be initiated and halted. The industrial and water service industries regularly employ check valves. Check valves are available on our website along with a variety of Valves.

• Dual Plate Check Valve Manufacturer in USA
Valvesonly is a leading Dual Plate Check valve manufacturer in USA. The short-stroke, double-Disc action of dual plate check valves is spring-assisted for more dynamic behaviour and quick reaction to speed Rates. The valve was temporarily closed, which reduced noise levels and surge pressures to protect expensive pumping machinery from the wind. Backward flow cannot be handled by a twin plate check valve. It is sturdy despite its small size and light weight. The object is made up of two spring-loaded plates that are joined by a hinge pin. As the flow alters, the plates automatically close to prevent the medium from going the wrong way.
Dual Plate Check Valve Uses:
• It can also act as a backup system and is widely used both horizontally and vertically.
• In the event of a breakdown, it inhibits the movement of gas, fluid, and air backward and maintains a steady pressure.
Dual Plate Check Valve Working:
They are smaller and lighter because there are two plates instead of one like in a typical swing check valve. By drawing up at the heel first before swinging, a unique design of the plate opening prevents friction on the seat. As a result, seal wear and tear is reduced. Seal wear occurs more frequently since other designs can't provide this capability. A special hinge layout and spring action are employed to achieve this.
STRUCTURALLY MORE SOUND DESIGN:
The valve's cylindrical body gives it the appearance of any other pipe fitting. In comparison to a traditional swing check valve, a cylindrical body's stress distribution is significantly more uniform. The pressure-containing section of the Dual Plate Check Valve's cylindrical body can be made to support a significant amount of weight (thickness). For challenging/rugged loading conditions, this gives these valves a major advantage over conventional valves in terms of safety, cost-savings, and all-around adaptability.
Dual Plate Check valve is used in many industries like
• Gas and Liquid Pipelines Industry
• Water and steam system
• Cooling towers
• Water Treatment
• Mine Dewatering
