PVC Uniblock non-return valve with EPDM O-rings (glued) manufactured by Cepex.
Spring operated.
The non-return or check valves allow the fluid to flow in only one direction of the installation, making it possible to work without fluid in the other direction or to avoid situations of undesired emptying of the line.
Installation by means of connections with nut on one side, facilitating assembly and maintenance.
Glue connections (also available with female threaded connections).
