585 Series

Swing Check Valve

The Cla-Val 585 Swing Check Valve is designed for long service
life and maintenance free operation. It has a full-flow area body
and is equipped with a disc arm with dual precision pins for opti-
mum disc connection and protection against damage due to
vibration. The body is fitted with a raised 300 Series Stainless
Steel seat as well as a resilient seat to help ensure drip tight seat-
ing, even in applications with high solids. The seats are replace-
able in the field without removing the valve from the pipeline.

The valve is constructed of Ductile Iron to provide greater dura-
bility and protection in applications with high stresses and shock
loads. The body and cover are fusion bonded NSF-61 epoxy
coated in accordance with AWWA C550 for long service life in
potable and non-potable systems.

During system flowing conditions the disc swings up to the open
position allowing unrestricted flow through the valve. When sys-
tem reverse flow conditions occur, the disc swings down to the
closed position, preventing reverse flow.
