Valve spring installation instructions

This information is by no means comprehensive. American Valve bears no responsibility for the improper installation or misuse of its plumbing valves. Please see our warranty and terms for more information. Cut tube straight and remove any burrs. Slip a standard crimp ring over the tube and then slip the tube over the valve. Pliers may be helpful. Position a calibrated crimp tool over the ring and compress it tightly. Turn on water and check for leaks.

Hose threads straight do not require any sealant. Do not disassemble the valve. Clean all the surfaces to be soldered with a fine sand cloth or steel wire brush to remove all traces of dirt and oil. Use a thin film of flux to cover the surfaces. Use flux sparingly, but be sure to cover the entire surface. Always use lead-free solder for plumbing parts. Open the valve fully and carefully to apply only as much heat as is needed to melt the solder. Message optional. Privacy Policy.

Our Disc Check Valve designed for a smooth action; the addition of a central guide offers further improved reliability when compared to traditional unguided disc check valves. Our Brass Spring Check Valves have an advantage in that they can be installed in an either horizontal or vertical position. As upstream pressure increases, the spring-loaded disc is forced open, lifting the disc from its seat to allow flow through the valve. Unpack and check that the valve is correct for its intended usage.

Check that the flow paths are clear and that the threads are free from debris. To ensure ease of operation, maintenance and repair, the location of the valve should be decided during the system design phase. Valves should be appropriately supported to prevent strain on the valve and the pipework. Spring Check Valves can be installed both vertically and horizontally and the valve needs to be closed during installation. Ensure that suitable pipe supports are used close to and either side of the valve to avoid bending the valve and remove any excessive stresses.
