This Standard establishes the minimum physical and performance requirements for in-line valves used withcross-linked polyethylene (PEX) systems. Establishment of these criteria provide for the protection of publichealth and the environment.
This Standard applies to in line-valves for use in radiant heating systems, and hot and cold water crosslinked polyethylene (PEX) distribution systems which are compliant with the requirements identified inASTM F877 for PEX tubing systems. Valves meeting these requirements are rated for a minimum100 psi (0.69 MPa) at 180 F (82 C). This Standard is supplemental to ASTM F877 and identifies additionalrequirements specific for valves. This Standard covers components intended for use in residential andcommercial, hot and cold, potable water distribution systems; and sealed central heating, including underfloorheating systems. This Standard excludes supply stops and fixture fittings (faucets).
