100mm Swing Check Valve
Product Overview
The 100mm Swing Check Valve is designed to prevent reverse flow in pipeline systems and protect pumps and equipment from backflow and sudden fluid reversal.
The disc opens under forward flow and closes automatically when flow reverses, driven by gravity and back pressure. The structure is simple, stable, and suitable for continuous operation conditions.
It is widely used in water supply, HVAC systems, industrial pipelines, and pump discharge lines.
Product Parameter
Design and Connection Standards: Designed to BS EN 12334 / API 6D; Flange drilling complies with EN 1092-2 PN16 or ASME B16.1.

Core Advantages
The full-bore design allows the disc to clear the flow path entirely, which minimizes pressure drop and reduces long-term pumping energy costs.
Every unit undergoes hydrostatic testing-calibrated at 24 Bar for the shell and 17.6 Bar for the seat (on 1.6Mpa rated valves)-to confirm dependable shut-off before leaving the factory.
Covered inside and out with a fusion-bonded epoxy coating over 250 microns thick to protect the ductile iron body against corrosion in damp or buried environments.

An internal, enclosed stainless steel hinge pin design eliminates external body penetrations to eliminate potential joint leak paths.
