Detailed Description

Wafer type dual plate check valve: metal seated vs resilient seated

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.

According to the structure of the check valve, it can be divided into three types: lift check valve, swing check valve and butterfly check valve. Lift check valves can be divided into two types: vertical and horizontal. Swing check valves are divided into three types: single valve, double valve and multi valve. The butterfly check valve is a straight-through type. The above-mentioned check valves can be divided into three types in connection form: threaded connection, flange connection and welding. A check valve is a valve that can automatically prevent fluid from flowing back. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve flap is

gravity and other factors to prevent the fluid from flowing back.

Classification of wafer dual plate check valves: hard-seal wafer dual plate check valve and soft-seal wafer dual plate check valve; of which soft-seal wafer check valve is divided into full-lined soft-seal wafer check valve and Semi-lined/normal soft-seal wafer dual plate check valve.

Features of Wafer dual plate Check Valve:

  1. Simple structure and light weight, especially suitable for low-pressure large-diameter pipelines;
  2. The paired clamp connection mode, the production process is simple, and the disassembly and assembly are convenient;
  3. The check valve adopts the clamp type, the butterfly plate is two semicircles, and the spring is forced to reset. The sealing surface can be built-up welding wear-resistant material or rubber lining, with a wide range of use and reliable sealing.
