WTO.厄瓜多尔通报第090号技术法规“减压阀”第二次修订草案（2R）

编号：G/TBT/N/ECU/413/Rev.2

厄瓜多尔技术法规规定了在销售国产和进口产品之前，减压阀应满足的要求，目的是保护人身安全和防止欺骗行为。
适用于以下产品：水减压阀：

1.公称直径为DN 8（1/4“）至DN 100（4“）的水减压阀和组合水减压阀，用于水输入压力不超过1.6 MPa（16bar），水温不超过30℃ºC和80ºC分别用于冷水和热水应用（用于建筑和施工）。

2.用于或连接到地下或地下供水管道系统的水减压阀，用于输送人类用水（用于市政饮用水网络）。

3.用于农业灌溉系统的水减压阀，公称直径为DN 8（1/4“）至DN 100（4“），用于温度高达60℃的水ºC。

4.消防系统中使用的水减压阀。

5.用于降低垂直管道系统或自动喷水灭火系统供水管道中水压的直接作用减压阀和限压阀。

英文原文：

The notified Ecuadorian Technical Regulation establishes the requirements to be met by pressure-reducing valves, prior to the marketing of domestic and imported products, with the aim of protecting human safety and preventing deceptive practices.

It applies to the following products: Water pressure-reducing valves:

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

2.Water pressure-reducing valves used in or connected to above- or below-ground water supply piping systems that transport water intended for human consumption (for municipal drinking-water networks).

3.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.

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

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