One of the biggest and most rapidly expanding Check valve manufacturer in USA is Valvesonly. We provide our clients affordable valves without compromising on quality. We also produce check valves that are created to order. To make sure that our valves can resist tough situations, we put in extra time and effort. Our success in the valves sector is largely due to our harmonious workplace atmosphere.
Nearly every industrial application uses check valves as one-way or non-return valves. By limiting reverse flows, check valves, which are straightforward devices, prevent damage and ensure effective operations. Reverse flow may result in water hammer. In the event of a brake failure, check valves are utilised to stop the flow of gas, fluid, and air.
In order to prevent contaminated water from flowing back into pure water supply lines, check valves are installed in water systems. There are many different types of check valves that can be used in a wide range of applications and use a number of materials, including metal, polymers, and rubber.

Advantages of check valve:
• Prevent backflow damage to pumps and compressor equipment.
• It decreases production losses and downtime brought on by improper valve failure.
• Check valves significantly decrease water hammer.
• It requires little upkeep.
Different Types of check valves:
 Swing check valve
 Wafer check valve
 Ball check valve
 Lift check valve
 Dual plate check valve
 Silent check valve

• 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
