Sprinkler system pressure relief valves are mostly installed in places where the terrain is steep and the water pressure of the pipeline changes direction etc which can easily rise sharply. Pressure relief valves are designed to relieve excess pressure from fire protection systems due to thermal expansion and are intended for installation downstream of the pressure reducing valves. AGFs Model 7000 Pressure Relief Valve. Pressure relief valves are designed to provide protection from over-pressure in steam gas air and liquid lines. Designed for Fire Protection applications. Approved pressure relief valves designed specifically for fire sprinkler systems.

The Nfpa 13 Ul Fm And Manufacturer Requirements For Pressure Relief Valves Downstream Of Installed Pressure Reducing Valves

Sprinkler system pressure relief valve. Relief valves and back pressure regulators are the same device only differing in application. Designed for Fire Protection applications. If that valve is not operating properly you might experience a significant change in water pressure.

To regulate the pressure of the drip zone on your sprinkler system you can install a pressure regulator like this one. For example excess heat can cause the water within the pipe to expand and possibly rupture the pipe fittings or sprinklers. The Model A is available factory-set at the following nominal operating pressures.

Pressures up to 350 psi 2413 kPa 24 bar. Ad Manufacturers of Safety relief Valves supplied worldwide. In accordance with NFPA 13 2010 edition Sec.

Approved pressure relief valves designed specifically for fire sprinkler systems. MALVERN PA August 5 th 2021 AGF Manufacturing is excited to introduce two new lockable pressure relief valves Model 7000L and Model 7200L specifically designed for the fire sprinkler industry. If the system has a higher working pressure the valves must perform in accordance with the requirements of the system.

175 psi 12 bar 185 psi 13 bar 210 psi 14 bar 260 psi 18 bar or 310 psi 21 bar. The purpose of the relief valve is to prevent excessive pressure build up within the automatic sprinkler system. Built using cast bronze and stainless steel this pressure control valve has standard adjustability from 20-200psi.

These models can be temporarily locked closed to allow for hydrostatic testing without removing the pressure relief valve from the system saving significant time. Pressure relief valves are designed to relieve excess pressure from fire protection systems due to thermal expansion and are intended for installation downstream of the pressure reducing valves. Pressure valve P4000A comes with 34 pressure relief valve which is designed for fire sprinkler system relief.

The Model A Relief Valve RV is UL Listed and FM Approved as a fire protection system pressure RV for installation in accordance with NFPA 13 NFPA 20 and FM Property Loss Prevention Data Sheets. Pressure regulating valves are typically used in high-rise nstallations where excess water pressure on lower floors must be reduced and regulated.
