Comer Non Return Valve

Comer Non Return Valve

Comer Non Return Valves are made from the highest quality PVC (unplasticised polyvinyl chloride) and manufactured in Italy to European standards. Our valves are widely used throughout the United Kingdom.

We stock Standard and Industrial options in both metric and inch variants with EPDM rubber seals. Sizes provided are: 3/8″- 4″.

Use

A non return valve is used to limit the flow of fluid in a single direction by use of a PVC cone with stainless steel spring. Versions of this type of valve may be manually or automatically operated. Automatic valves are designed for a particular pressure. If the pressure exceeds that limit the valve opens allowing flow through it.
