Pressure-reducing valves (HS code(s): 8481.10)

Proyecto de Segunda Revisión del Reglamento Técnico Ecuatoriano PRTE 090 (2R) "Válvulas reductoras de presión" (Draft second revision (2R) of Ecuadorian Technical Regulation (PRTE) No. 090: Pressure-reducing valves); (12 pages, in Spanish)

The notified Regulation applies to the following products:

·        Water pressure-reducing valves and combination water pressure-reducing valves, with nominal diameters from DN 8 (1/4") to DN 100 (4"), for inlet pressures not exceeding 1.6 MPa (16 bars) (232 psi) and water temperatures not exceeding 30ºC for cold water application and 80ºC for hot water application (used in building and construction).

·        Water pressure-reducing valves used in or connected to above-ground or buried water supply pipelines that transport water intended for human consumption (for municipal drinking-water networks).

·        Water pressure-reducing valves intended for use in agricultural irrigation systems, with nominal diameters from DN 8 (1/4") to DN 100 (4"), for use with water at temperatures up to 60ºC.

·        Water pressure-reducing valves used in fire-fighting systems.

·        Direct-acting pressure-reducing and pressure-limiting valves for reducing water pressure in vertical pipeline systems or sprinkler system supply pipes.
