Cast Iron Check Valve – Flanged PN16 – EPDM Seat

This cast iron flanged check valve with an EPDM seat is tailored for utility water, chilled/hot water or general HVAC systems. The cast iron body delivers structural strength, the EPDM seat ensures reliable sealing, and the PN16 flanged configuration makes installation straightforward in standard pipelines.

Technical Data

• Body Material: Cast iron (EN GJL‑250 or equivalent) offering structural durability for industrial/utility service.

• Seat Material: EPDM (ethylene‑propylene-diene rubber) liner or ring, ideal for water, mild fluids, and resistance to heat/cold cycling.

• Connection Type: Flanged ends rated PN16, drilled to standard flange patterns for compatibility.

• Temperature Range: Approx. –10 °C to +120 °C under water service conditions with EPDM seat.

• Operation Type: Swing or lift disc depending on size; designed for horizontal installation.

• Size Range: Typically DN50 to DN300 (2″–12″) for this style of valve.

Key Features

• EPDM seat provides tight shut-off and long service life in water/utility systems.

• Cast iron body offers cost-effective strength for large-bore pipelines.

• Flanged PN16 design supports standard installation with minimal modification.

• Low-maintenance and suitable for building services or utility systems.

Typical Applications

• Water distribution mains in commercial/industrial buildings.

• HVAC chilled or hot water loops where non-return valves are needed.

• Pump discharge or return lines in utilities and mechanical plantrooms.

• General service fluid lines where cast iron and EPDM sealing are adequate.
