PVDF Wafer Check Valve is with sediment sieve as a safety filter to catch any solid contaminants that may sometimes be in the line. We export small hole valves and other equipment, such as pumps or control valves, protected by it. The filter screen is easily replaceable and is available in a variety of meshes.
An oscillating disc is used to open or close the valve. As a result of their design, they can be installed in extremely tight spaces where a flanged check valve would be ineffective. As the disc opens, the PVDF wafer check valve has a molded body surrounding the opening.
In contrast, PVDF wafer check valves have a molded body that allows the disc to open completely, enabling full flow. In the case of applications that demand full flow, this is an important consideration, as you can see.
Therefore, PVDF wafer check valves are used in situations where flow is not a concern. Swing checks are used in applications where a full port valve is required.
The CR wafer check valve is designed to be installed directly between stubs and flanges in accordance with ISO/DIN standards.
• Installed with FIP QPV (d50 – d160) stubs and QRV stubs using flat gasket
QHV/Y (d225 – d315), on PVC piping class PN10 or lower with type ODV
• Metal support for easy and precise centring of the valve during installa-
• Can be installed in either a vertical or horizontal position
• Sealing system with O-ring for optimum sealing and installation without
