Valvesonly is a leading and reputed Check valve manufacturer in USA. These valves perform traditional functions in a more sophisticated manner regardless of where they are used. In the event of a brake failure, check valves are utilised to prevent the reverse flow of gas, fluid, and air. These self-activating relied valves are used to start and stop liquid flow. In the industrial and water service industries, check valves are commonly utilised. Check valves with a variety of attachments are available on our website.
Check valves are self-activating valves that only allow gases and liquids to flow in one direction. The purpose of a check valve is to prevent the flow of a process from reversing in the system, which could cause damage to equipment or cause the operation to be disrupted. They're known as one-way directional valves. Check valves are commonly employed to prevent backflow in liquid pumps and gas compressors, which could cause the pump or compressor to shut down. They're also employed in process systems that require multiple pressures to be kept separate. They don't require any external electricity to operate because they rely on the pressure drop created by the medium flow.

Applications of check valves:
With the use of check valves, backflow is prevented and pressure is maintained. They're commonly used as a backup if a pump fails, to aid compressors and reciprocating pumps, and when the system pressure exceeds the primary equipment's capabilities. Refining, petrochemical, chemical, and oilfield activities, as well as water, steam, refining petro, and viscous fluids, all use check valves. In waste-water management and manufacturing systems, check valves are also common.
Types:
• Swing check valve.
• Ball check valve.
• Lift check valve.
• Dual plate check valve.
• Silent check valve.
• Non slam swing check valve.
• Tilting disc check valve.
• Pressure seal check valve.
Advantages of check valves:
· Prevents backflow.
· Maintains pressure.
· Serves as backup system.

Dual Plate Check Valve Manufacturer in USA:
Valvesonly is a leading Dual Plate Check valve manufacturer in USA. Dual Plate check valves have a short-stroke, spring-assisted twin Disc action for increased dynamic behaviour that reacts fast to speed Rates. The valve has been enclosed for a fraction of a second, decreasing loud noise and lowering surge pressures to protect expensive pumping machinery from wind. Backward flow is not permitted through a Dual Plate Check valve. It is little and light in weight, but it has a powerful nature. It's made up of two spring-loaded plates that are joined by a hinge pin. When the flow changes, the plates close on their own, preventing the medium from flowing backwards.
Dual Plate Check Valve Uses:
· It inhibits backward flow of gas, fluid, and air in the case of a breakdown.
· It maintains a consistent pressure.
· It can also function as a backup system.
· It's often used in both horizontal and vertical application.
Dual Plate Check Valve Working:
Because there are two plates instead of one in a traditional swing check valve, the plates are smaller in area and lighter in weight. Plate opening is unique in that it first pulls up at the heel and then swings, ensuring no rubbing against the seat. As a result, the rate of seal wear and tear is reduced. Other designs are unable to include this functionality, resulting in a higher rate of seal wear. This is accomplished through the use of a unique spring action and hinge design.
STRUCTURALLY MORE SOUND DESIGN:
The valve's cylindrical body gives it the appearance of any other pipe fitting. When compared to a traditional swing check valve, a cylindrical body has a considerably more consistent stress distribution. The pressure-containing component of the Dual Plate Check Valve's cylindrical body can be constructed to sustain a large amount of weight (thickness). As a result, these valves have a notable advantage over traditional valves for severe/rugged loading situations, both in terms of safety and economies, as well as general versatility.

AWWA Check Valve Manufacturer in USA:
Valvesonly is the best AWWA Check Valve Manufacturer in USA. AWWA stands for American Water Works Association. AWWA Check Valves are used in wastewater, water, oil and gas and sewage applications. AWWA Check valves are used for preventing the reverse flow of gas, fluid, and air in the event of a brake failure. The flow of the medium is started and stopped using these self-activating relied valves.
These valves are self-activating check valves that allow just one direction of flow for gases and liquids. An AWWA check valve's job is to keep the flow of the process from reversing in the system, which could damage equipment or disrupt the operation. One-way directional valves are what they're called. These valves are often used to safeguard liquid pumps and gas compressors from backflow, which could cause the pump or compressor to shut down. They're also used in process systems with multiple pressures that need to be maintained separate. They work without the usage of external power since they rely on the pressure drop caused by the medium flow.
Material: Cast iron, Ductile iron
Size: 2” to 48”
Class: PN6 to PN25, ANSI 150
Ends: flanged, Wafer, Lug, Threaded, Buttweld, Socketweld
