Breetec’s standard range consists of basic elements that are modularly combined. For example, the basic type of pressure relief valve 1411 is combined with the negative pressure valve 1412R to form a pressure relief/underpressure valve type 1413R. The 1111 series of pressure relief valves has a side outlet that allows the discharge of hazardous or noxious gases in a closed system. These models are often mounted on tanks and silos in an indoor setup. The 1111 Series is combined with a 1412R Series vacuum valve to form an 1113R Pressure Relief/Vacuum Valve.
Breetec’s standard range consists of six elements that can be mounted in combination for many possible overpressure and underpressure situations. They can be supplied with three options: a bird net, grounding and proximity switch. In extreme weather conditions, the breathing valves can also optionally be insulated and heated
