Product Description

 Stainless Steel 304/316 Single plate Thin Single Disc Swing Wafer Check Valve CF8 DN100 PN16

The working principle of a Thin Single Disc Plate Check Valve is as follows:

1. Normal Flow: When the medium flows in the designed direction, the disc (single plate) opens under the pressure of the medium, allowing it to pass through.

2. Reverse Flow: When the medium flows in the reverse direction or the flow rate decreases, the disc quickly closes under the action of a spring or its own weight, preventing backflow.

3. Key Features:

   • Compact structure, suitable for limited installation space.
   • Quick response to avoid water hammer.
   • Single disc design reduces flow resistance.

It is widely used for one-way flow control in pipelines carrying liquids, gases, and other media.

BALL VALVES BY BODY STRUCTURE

One Piece Ball Valve (1PC)

The body is formed from a single body piece in a one-piece ball valve. The ball is permanently fixed within the valve body, and the ends are threaded or welded. One-piece ball valves are compact and cost-effective, commonly used in applications with lower pressure and smaller sizes.

Two Piece Ball Valve (2PC)

This type of ball valve consists of two separate pieces connected with thread or bolts. The body is divided into two halves, allowing easy access to the internal components, including the ball and seats. Two-piece ball valves are commonly used in applications requiring regular maintenance or inspection.

 

Three Piece Ball Valve (3PC)

Three-piece ball valves are constructed with three separate pieces: a body and two end caps. The end caps are connected to the body using bolts, allowing easy disassembly and maintenance. This ball valve type offers greater flexibility for repairing or replacing internal components.
