Description

Clapper check valve 

The clapper valve is a type of non-return valve but it incorporates a flapper that acts, with gravity, as a shutter. What this element does is to prevent the passage when the fluid moves in the undesired direction. They work by gravity so they have to be placed in a certain position. 

It is installed at the base of the suction pipe of a pump, between the pump and the tank, thus allowing the fluid to pass but preventing it from backing up into the tank. 

We have a wide range of dimensions and combinations to adapt the installation to your needs from 63 mm diameter up to 315 mm diameter and in a normal pressure of PN 6. 

Features PVC-U clapper valves

  • Small installation space required
  • Easy to install: mounted between standard flanges. No need for additional gaskets
  • Vertical and horizontal installation
  • Excellent flow characteristics

Important: Do not mount the valve at a distance of less than 5 x D from a pump outlet. Install with PN 10 pipe, if PN 16 is used, damage to the valve may occur. 

Specifications clapper valve

  • 0.1-3 bar: Minimum downstream pressure to keep the valve closed, depending on installation conditions.
  • PVC-U body
  • O-rings in EPDM
  • Blue marking: EPDM seals, to be chosen according to the fluid.

Note: It is important to choose the type of valve according to the fluid and therefore to choose between EPDM or FPM (Viton) seals.
