UPVC Wafer Check Valve Manufacturer & Supplier in India. As a safety filter, sediment strainers are meant to catch any solid pollutants that may sometimes occur in the line.
We are the valve exports and other equipment with tiny orifices, such as pumps or control valves, are protected by this. The filter screen is simply changeable and available in a variety of meshes.
An oscillating disc is used to open or close the valve. As a result of their design, they may be installed in exceedingly tight places, where a flanged check valve would be ineffective.
As the disc opens, these valves have a moulded body surrounding the opening. In contrast, UPVC Wafer Check Valves have moulded bodies that enable the disc to fully swing open, enabling full flow.
In the case of applications that demand full flow, this is a critical consideration, as you can understand. Therefore, wafer check valves are used in situations where flow isn’t a concern. Swing check Valves are used in applications where a full port valve is needed.
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

For water e non-hazardous fluids with regard to which the material is classified as CHEMICALLY RESIS-TANT. In other cases, a reduction of the nominal pressure PN is required (25 years with safety factor).
The Kv 100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20°C that will generate Δp= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely
