Valvesonly is a leading Dual Plate Check valve manufacturer in USA. The Dual Plate Check Valve is manufactured with unblemished trim for years of trouble-free use. The Dual Plate Check Valve is used in clean water or air pipelines that run horizontally or vertically. This valve isn't designed to hold fluids that contain particles, such as waste or raw waste. Dual Plate Check Valves come in wafer, flanged wafer, and extended designs with flanged ends that have the same face-to-face proportions as a swing check valve.
This valve should not be used with fluids that contain hazardous gases. It is designed to produce flow in the direction indicated by the arrow on the surface plate, and to close quickly when flow reversal is detected. The plate will list the valve size, model number, working pressure, and construction materials. When the fluid in the line is flowing in the opposite direction, the check valve enables flow in one direction but automatically prevents backflow. The clack valve or non-return valve is another name for a check valve.
Two spring-loaded plates are hinged on a central hinge pin in the Dual Plate Check Valve. Torsion springs seal the plates when the flow drops activity that does not necessitate reverse flow This design has a lot to offer. the benefits of not using a water hammer and not using a slam simultaneously.

VALVE OPERATION:
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.

The dual plate check valve has the following benefits:
• 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 is used in many industries like
• Gas and Liquid Pipelines Industry.
• Water and steam system.
• Cooling towers.
• Water Treatment.
• Mine Dewatering.

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.
