(b) Expansion-control valves.
(c) Non-return valves.
(d) Temperature-relief valves.
(e) Combination high-pressure expansion non-return valves (HPNR).
(f) Leak-protection devices.
The valves specified in this Standard are primarily intended for use in warm and hot water systems that are required to operate at —
