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

This model incorporates the same robust materials as above but adds the leverandweight mechanism to improve closure under lowflow or reverseflow conditions, while maintaining a stainlesssteel seat for longterm durability.

Technical Data

• Body Material: Cast iron
• Seat Material: Stainless steel for highduty 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: DN50DN300 typical

Key Features

• Lever and weight enhance closure in slowflow 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 chilledwater systems with variable flow velocities.
• Industrial fill/return lines with mixed or variable flow conditions.
• Mechanical plantrooms or pumping stations where backflow risk must be minimized under all conditions.
