## Summary description

Spring check valve ARCO 3/4" F-F with a metal piston (MPN 191404, EAN 8428519077535). Designed for one-way flow control in fluid systems, this female-to-female valve uses a spring-loaded metal piston to prevent backflow. Suitable for plumbing and industrial fluid applications where compact, reliable non-return performance is required.

## Long description

Spring check valve ARCO 3/4" Female-Female with a metal piston is a compact one-way valve designed to prevent backflow in fluid systems. The valve features a spring-loaded metal piston that responds to differential pressure, opening to allow forward flow and closing reliably to block reverse flow. Its female-to-female threaded ends provide straightforward inline connection in piping systems commonly used in plumbing and light industrial installations.
Advantages
The metal piston and spring mechanism deliver consistent non-return performance and good resistance to wear in many water and non-corrosive fluid applications. The female threaded connections enable easy installation between standard pipe fittings without additional adapters. Its compact construction minimizes space requirements while offering a quick response to pressure changes, ensuring system protection against backflow.
Suitable for
 Domestic and commercial plumbing systems to prevent siphoning or backflow
 Boiler feed and condensate return lines
 Compressed air and pneumatic lines with non-corrosive media
 Cooling circuits and recirculation loops in industrial equipment
Key specifications
 Connection type: female-to-female threaded ends, nominal 3/4"
 Check mechanism: spring-loaded metal piston for one-way flow control
 Material: metal valve body and metal piston suitable for general fluid service
 Operating principle: pressure differential-actuated opening and spring-return closing
 Installation orientation: inline, horizontal or vertical depending on system layout (follow manufacturer guidance)
How to use
Install the valve inline with the flow direction indicated by the valve orientation so the piston opens toward the downstream side. Ensure pipe threads are clean and use appropriate thread sealant or tape compatible with the conveyed fluid and valve materials. Tighten to secure connection without over-torquing to avoid damaging threads. After installation, pressurize the system and check for leaks; verify that forward flow passes freely and that no reverse flow occurs when downstream pressure exceeds upstream pressure.
Usage recommendations
Use this spring check valve with water and non-corrosive fluids. Avoid use with highly abrasive, corrosive, or particulate-laden media that could impair piston movement. For systems with low differential pressure, confirm that the spring cracking pressure is suitable for your application; consult technical documentation or test in situ. Periodic inspection and maintenance are recommended to ensure reliable operation, especially in environments with potential contamination.
