Cast Iron Check Valve – Flanged PN16 – Stainless Steel Seat – Lever & Weight

This model incorporates the same robust materials as above but adds the lever‑and‑weight mechanism to improve closure under low‑flow or reverse‑flow conditions, while maintaining a stainless‑steel seat for long‑term durability.

Technical Data

• Body Material: Cast iron

• Seat Material: Stainless steel for high‑duty use

• Connections: Flanged ends, PN16 rated

• Actuation Mechanism: Lever and weight assembly attached to swing disc to aid rapid closure

• Temperature Range: Up to +300°C

• Pressure Rating: PN16 ( 16 bar )

• Installation Orientation: Horizontal preferred

• Sizes: DN50‑DN300 typical

Key Features

• Lever and weight enhance closure in slow‑flow conditions where standard swing may not reliably seat.

• Stainless seat ensures robust performance across many cycles and variable media.

• Cast iron body offers strength while keeping overall cost down.

• Ideal for installation in utility systems where reliability under adverse conditions is required.

Typical Applications

• Large HVAC or chilled‑water systems with variable flow velocities.

• Industrial fill/return lines with mixed or variable flow conditions.

• Mechanical plantrooms or pumping stations where back‑flow risk must be minimized under all conditions.
