Dual Plate Wafer Check Valve Manufacturer in Africa

Product Introduction

Space-saving pipeline components are often preferred in systems where weight, installation length, and maintenance accessibility are important considerations. A Dual Plate Wafer Check Valve is engineered to prevent reverse flow while occupying significantly less face-to-face space than conventional swing check valves. Its wafer-style body fits directly between pipeline flanges, and the spring-assisted dual-disc mechanism closes rapidly when flow stops, reducing the possibility of reverse flow and hydraulic shock. African Valve is a Largest Dual Plate Wafer Check Valve Manufacturer in Africa, manufacturing and supplying Dual Plate Wafer Check Valves in various material grades, pressure classes, seat configurations, and wafer body designs for projects across Nigeria, Egypt, South Africa, Kenya, Ghana, and other African countries, along with international export destinations.

Flow Characteristics

The compact disc design helps ensure that the valve opens up at a fairly low cracking pressure level with little resistance to the forward flow. As the rate of flow falls, the twisting spring starts to shut both the plates before the reversal in the direction of the flow occurs, hence limiting the effects that are experienced in a conventional non-return valve.

Valve Construction

The valve Components include a body made of a wafer, two semi-circular plates, a hinge shaft, a torsion spring, a valve seat, and retaining devices. The two plates rotate individually along the axis and need just a small rotational motion to move into a completely open state. These characteristics allow for a smaller size that results in less inertia of the disc and rapid closure of the valve.
