## Summary description

Set of straight valves ARCO KCM14 comprising a supply (feed) valve and a return valve with a metal nut, designed for 1/2"F connections and branded Teide Plus. Intended for plumbing and heating installations where a paired feed-and-return control is required. Useful for radiator connections, maintenance isolation and flow control in residential and commercial systems.

## Long description

Set of ARCO straight valves KCM14 contains a supply (feed) valve and a return valve with metal nuts designed for 1/2" female threaded connections. Branded Teide Plus, this paired valve set is intended for plumbing and heating installations where independent feed-and-return shutoff and flow regulation are required. The straight design and metal connection nuts provide a compact, durable solution for radiator connections, underfloor manifolds or branch lines in residential and commercial systems.
Advantages
The paired supply and return valves allow independent isolation of each circuit without disturbing the rest of the system. Metal nuts increase mechanical strength and ensure consistent tightening and sealing at the 1/2" connection. The straight configuration provides a direct flow path with minimal space requirements, simplifying installation in confined locations. The components are compatible with standard plumbing fittings for typical heating and radiator installations.
Suitable for
 Radiator connections where feed and return isolation is needed
 Residential and commercial heating circuits
 Maintenance and replacement operations on branch lines
 Compact installations with limited clearance
Key specifications
 Connection type: straight 1/2" female threaded
 Set composition: supply (feed) valve and return valve
 Nut material: metal
 Application: plumbing and heating systems (radiators, branch lines)
 Design: straight configuration for compact installation
How to use
Install the supply valve on the feed pipe and the return valve on the return pipe using the 1/2"F threaded connections. Ensure pipe ends and fittings are clean and use appropriate sealing (such as PTFE tape or thread sealant) on male threads before tightening the metal nuts by hand and then with a wrench to the recommended torque for the piping material. Open and close each valve to check operation and verify leak-free connections under system pressure. For systems with thermostatic heads or actuators, fit those components after the valve installation as required.
Usage recommendations
Use compatible sealing materials and follow local plumbing codes. During installation, avoid overtightening the metal nuts to prevent thread or fitting damage. Periodically check valves for leaks and proper operation, and perform maintenance or replacement when signs of wear or leakage appear.
