In any commercial HVAC system, maintaining unidirectional flow is critical for pump protection and system efficiency. Unlike isolation valves (Gate/Ball) or regulation valves (Globe/Balancing), HVAC Check Valves—commonly known as Non-Return Valves (NRVs)—operate automatically to prevent the reverse flow of fluids.
At FIFFCO GLOBAL LTD, we supply robust Check Valves engineered for the UK’s mechanical services sector. Whether you are managing a Low Temperature Hot Water (LTHW) network or a Chilled Water (CHW) riser, our valves ensure your fluid dynamics remain stable, compliant, and efficient.
Our range is manufactured to strict BS EN 12334 standards, ensuring durability under the variable loads of modern building services. We offer versatile material options to suit specific pipework requirements:
The primary function of our HVAC Check Valves is to protect critical equipment from damage caused by gravity circulation or back pressure. They are essential in:
We understand that downtime on a mechanical site costs money. Fiffco acts as your supply chain partner, not just a vendor.
The main purpose is to allow fluid to flow in only one direction. It automatically closes to prevent backflow, protecting pumps from reverse rotation and preventing water hammer in the pipework.
Selected models within our Check Valve range are WRAS Approved for use with potable (drinking) water. Please check the individual product specification tab or contact our technical team to confirm suitability for mains water supplies.
It depends on the mechanism. Swing Check Valves must be installed horizontally or vertically only if the flow is upwards. Spring Check Valves are more versatile and can generally be installed in any orientation, provided the pump pressure is sufficient to overcome the spring tension.
Ensure your mechanical systems are protected against backflow and reverse pressure. Trust Fiffco for industrial-grade valves that meet British Standards.
