  6. Description of content : 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.  
7. Objective and rationale, including the nature of urgent problems where 
applicable : Consumer information, labelling ; Prevention of deceptive practices and 
consumer protection ; Protection of human health or safety
