65-45-12, Class B Ductile Iron coated and lined with an

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 opti­mum 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 seat­ing, even in applications with high solids. The seats are replace­able in the field without removing the valve from the pipeline.

The valve is constructed of Ductile Iron to provide greater dura­bility 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 sys­tem reverse flow conditions occur, the disc swings down to the
closed position, preventing reverse flow.

Closure Options

The disc shall be raised one-piece Stainless Steel construction
and equipped with a molded resilient seat mounted on the disc
with an integral )-Ring for drip tight sealing. Both seats shall be
secured with stainless steel fasteners and must be field
replaceable without removing the valve from the pipeline.
