NR-47 | Removable Cover Check Valves

PN 6 / 10 / 16

A check valve with a resilient disc, allows for one-directional flow and prevents liquid return to its source.

This valve has a removable upper cover which allows for the cleaning and maintenance of the valve without the need to remove it from the pipeline.

The valve disc is rubber-coated and attaches to a shaft, which is locked into the valve body.

Sealing is performed by the closing of the disc up against the valve seat, located at the inlet to the body.

Valve size range: 2" – 20"
Work pressure: 6/10/16 bar
Maximum working temperature: 60°C.
Valve coating: oven-cured blue epoxy
Cast body made to withstand surge
Internal parts are made of durable non-corrosive materials, allowing for long term operation under harsh conditions.
Minimal energy losses and smooth water flow, achieved by the complete elevation of the disc into the upper cover opening.
Vulcanized disc – for sealing at low pressure and preventing wear of the sealing area

The disc is reversible - doubling the life time for use
Soft sealing according to Standard EN 12334
Rubber stoppers restrain the movement of the disc at the maximum opening height; no contact between coated metal parts prevents damage to the coating.
