## Long description

The ARCO 191406 check valve is a metal-seat non-return valve engineered to prevent reverse flow in piping systems. It has female threaded connections sized 1¼" F and 1½" F designed for inline installation. Constructed from metal components, the valve offers mechanical strength and a tight shut-off suitable for protecting pumps, fixtures and piping from backflow. It is intended for use with water and other non-aggressive fluids in residential and light commercial plumbing systems.
Advantages
The metal seat provides durable sealing performance and resistance to wear under repeated cycling. Female threaded connections allow straightforward inline replacement or installation without additional adapters when matching threaded pipe fittings are used. The compact design and robust construction reduce the risk of leakage and require minimal maintenance under normal operating conditions.
Suitable for
Preventing backflow in domestic water supply lines
Protecting pumps and circulation equipment from reverse flow
Use in light commercial plumbing and service lines
Applications with non-corrosive liquids compatible with metal components
Key specifications
Valve type: non-return (check) valve with metal seat
Body material: metal construction for durability
Connection type: female (internal) threaded on both ends
Connection sizes: 1¼" F and 1½" F (female threads)
Flow orientation: inline, permits flow in one direction only
Recommended fluids: water and non-aggressive liquids
How to use
Install the check valve in-line with the flow direction indicated by the valve orientation; ensure the larger and smaller female threaded ends match the corresponding pipe fittings or adaptors. Use appropriate thread sealant or tape on threaded joints to ensure a leak-tight connection, and tighten with suitable tools without over-torquing to avoid damaging threads. Verify correct operation by pressurising the system and confirming there is no reverse flow when downstream pressure is applied.
Usage recommendations
For reliable performance, select installation locations free of heavy suspended debris and ensure the valve is accessible for inspection. Avoid use with aggressive chemicals that may attack metal surfaces. Periodically check seals and threaded joints for tightness and signs of wear, and replace the valve if leaks or impaired sealing occur.
