Dual Plate and Wafer Type Check Valve
Jul . 17, 2024
The main purpose of the Dual Plate Wafer Check valve is to perform the work of almost any conventional valve. However, being smaller makes it lighter and, therefore, is more cost efficient to purchase, install and maintain. It is also a silent check valve; because of it’s innovative design, it does not slam upon closing. The Dual Plate Wafer Check plate design and flat seat offer many advantages. The flat seat eliminates any possibility of board snaps in the seat, which snaps occur frequently in other valves. When suspended in a vertical pin, the two plates have a reduced weight which eliminates excessive wear on the plate lugs. This wear can cause the plate to collapse on the seat’s open surface, causing the valve to subsequently fail. An important feature of the Dual Plate Wafer Check valve is that it does not depend on the pressure or flow to center the plates in relation to the sealing surface in order to make the seal. Single plate conventional designs, even those having centering guides, require a backpressure and backflow to center the plate to the seat in order to get a non leakage adjustment. This feature becomes extremely risky in the event of reduced flow and the handling of gases at low pressure. Size Pressure by class according to ASME/ANSI B16.34 Ends 2″ a 60”

What are dual plate check valve?
Jul . 17, 2024
Dual Plate Check Valve is manufactured based on API 594 standard. To allow the installation of the stop-pin and hinge-pin of the check valve without having to drill through the valve body completely, the valve is designed to be retainerless. The valve plate acts as a door resting freely on the inclined valve seat surface. In order to ensure that the valve plate matches the correct position of the valve seat every time it is operated, the valve plate plays a vital role to ensure that it has enough swing space so that it is truly and completely accessible to the valve seat.

DUAL PLATE CHEC
Jul . 17, 2024
The Dual Plate Check Valve is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or lift check valve.The Dual Plate Check Valve design is the outcome of attempts to solve the problems associated with conventional swing check valve and lift check valve. The Dual Plate Check Valve employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. This design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together make the Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVEDual Plate Check Valve can be classified as Zero Velocity Valve . The design has everything which the other conventional valves miss. It is a valve most efficient in operation irrespective of fluid and service conditions and the easiest to handle and install in any piping system with no constraints.

Dual Plate vs. Swing Check Valve
Jul . 17, 2024
Check valves are automatic valves that open with forward flow and close against reverse flow. The different groups of check valves include swing check valves, lift check valves, dual plate check valves, etc. The main function of a check valve is to protect the mechanical equipment in a piping system by preventing fluid reversal.Additionally, the function of a check valve is to stop massive backflow when a pipe breaks and prevent backflow toward lower pressure. Generally speaking, a check valve has no requirement for operators and the valve is operated automatically through fluid flow or flow reversal. In a swing check valve, the closure member swings around the hinge, which is mounted in the seat. Figure 1 shows a swing check valve with the disk moving away from the seat by the force of the water to keep the valve open.

Wafer type dual plate check valve: metal seated vs resilient seated
Jul . 17, 2024
Wafer dual plate check valve is used for pure pipelines and industrial, environmental protection, water treatment, high-rise building water supply and drainage pipelines, to prevent the reverse flow of the medium. The check valve adopts a clamp type, the butterfly plate is two semicircles, and it adopts a spring for forced reset. The sealing surface can be built-up welding wear-resistant material or rubber lining, with a wide range of use and reliable sealing.The check valve opening and closing parts are opened or closed automatically by the flow and force of the medium to prevent the medium from flowing back. The valve is called the check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents.
