scope:

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 in ASTM F8772F ³ for PEX tubing systems. Valves meeting these requirements are rated for a minimum 100 psi (0.69 MPa) at 180 °F (82 °C). This standard is supplemental to ASTM F877³ and identifies additional requirements specific for valves. This standard covers components intended for use in residential and commercial, hot and cold, potable water distribution systems; and sealed central heating, including underfloor heating systems. This standard excludes supply stops and fixture fittings (faucets).

Purpose

This standard establishes the minimum physical and performance requirements for in-line valves used with cross-linked polyethylene (PEX) systems. Establishment of these criteria provide for the protection of public health and the environment.
