PVC Non Return Check Valve / Wafer Check Valve DN40 - DN300 With EPDM Seals

PVC Wafer Swing Check Valve with EPDM Seals, PN 10 Bar , DN 40-DN 300

Check Valve PRODUCT INTRODUCTION

Description

A Wafer Check Valve, or dual plate check valve, offers ease of maintenance and exceptional flow characteristics with the dual plate valves that give maximum strength with minimum opening time. The one piece design is available in metal or plastic materials to provide appropriate corrosion resistance for your application needs.

Features

• 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 flanges

• Metal support for easy and precise centring of the valve during installation

• Can be installed in either a vertical or horizontal position

• Sealing system with O-ring for optimum sealing and installation without flat gaskets

Installation

During installatin, make sure that the following requirements are complied with:

Leave a straight section of pipe of length equal to 5 times the nominal diameter before and after the valve.
Do not install the valve directly on the pump flange. The use of flat gaskets is rec- ommended in order to guarantee a perfect seal between the valve and stubs with serrated face.
Do not use pipes of thickness more than that of PN10 pipes.
The CR valve can be used on vertical pipes only if the fluid flow is upwards.
After having aligned the valve with the stub, tighten the flange bolts in a diagonal sequence to the required torque.
