At ISIS Fluid Control, our check valves are engineered to deliver robust, one-way flow protection across a wide variety of systems. Also known as non-return valves (NRVs) or one-way valves, these components are essential for maintaining fluid direction, preventing reverse flow, and safeguarding sensitive equipment from potential backpressure damage.
We offer a carefully curated selection of check valve types to suit different industrial needs:
Swing Check Valves – Ideal for low-velocity, horizontal flow systems such as water, wastewater, and general industrial applications.
Wafer Check Valves – Slim-profile valves designed for compact spaces, commonly used in HVAC and high-efficiency fluid systems.
Poppet Check Valves – Precision-engineered for use in high-pressure and fast-reacting hydraulic or pneumatic circuits.
Threaded Check Valves – A reliable option for general plumbing, heating, and process installations where threaded connections are standard.
These valves are available in a range of high-performance materials, including brass, stainless steel, carbon steel, and bronze, making them suitable for both corrosive and non-corrosive media. End connection options such as threaded, flanged, and SAE ensure flexibility across installation types.
From hydraulic and pneumatic applications to chemical processing and water treatment systems, our check valves are trusted by engineers worldwide for their durability, responsiveness, and leak-tight reliability.
With technical support based in the UK and global distribution capabilities, ISIS Fluid Control ensures that each customer receives the right valve solution tailored to their industry and operational needs.
Trust ISIS Fluid Control for expertly specified check valves that protect your systems and support long-term performance.
