Ductile Iron Check Valve – PN16 Lever & Weight – WRAS Approved

This lever‑and‑weight assisted ductile iron check valve is engineered for potable water systems where the risk of back‑flow must be strictly controlled and compliance with regulatory standards is essential. With WRAS approval and a repair‑friendly design, it’s well suited for utility mains and pumping stations.

Technical Data:

• Body material: Ductile iron (EN GJS‑450‑10 or similar) epoxy‑coated for corrosion resistance.

• Seat material: Metal seating ring for durability under repeated cycles.

• End connection: Flanged ends rated PN16 (16 bar nominal) conforming to BS EN 1092‑2 flange standard.

• Operating temperature range: -10 °C up to approx. +70 °C

• Pressure Rating: PN16 ( 16 bar )

• Mechanism: Swing disc with externally mounted lever and adjustable weight for improved closure under low‑flow or reverse‑flow conditions.

• Sizes available: DN50 (2″) up to DN300 or more in standard range.

Key Features:

• WRAS‑approved construction makes it suitable for drinking water systems.

• Lever and weight addition supports more reliable closure under conditions where flow reversals or pump shutdowns might cause water‑hammer or back‑flow.

• Full‑face flanged body offers full‑bore flow, minimal pressure drop, and ease of maintenance.

• Ductile iron body adds strength and durability compared to standard cast iron in demanding installations.

Typical Applications:

• Pump discharge or return lines in municipal water supply networks.

• Booster stations and high‑rise building main supply risers where compliance is mandated.

• Industrial water systems requiring certified back‑flow prevention under moderate pressure.

Summary:
For installations where potable water, compliance and robust performance are non‑negotiable, this ductile iron check valve with lever & weight offers a dependable solution. Its design targets serious back‑flow prevention, long service life and straightforward installation in flanged systems.
