Relief Valve, Body:316SS, Sealing:FKM, Max. Outlet Pressure:1,500psig, Conn.:1/4in. (M)NPT x 1/4in. (F)NPT, Set Pressure:4500~6000 psig. Orifice:3.6mm

◎ Set pressure: RV series: 7 color-coded springs available for a wide range of set pressure, 50 to 6000 psig @ 70°F (3.4 to 414 bar @ 20°C) RL series: 10 to 225 psig @ 70°F (0.68 to 15.5 bar @ 20°C) RM series: 3 color-coded springs available for a wide range of set pressure, 50 to 1500 psig @ 70°F (3.4 to 103 bar @ 20°C) ◎ Maximum outlet pressure: RV series: 1500 psig (103 bar) RL series: 225 psig (15.5 bar) RM series: 1500 psig (103 bar) ◎ Orifice size: RV series: 0.14" (3.6 mm) RL series: 0.19" (4.8 mm) and 0.25" (6.4 mm) RM series: 0.25" (6.4 mm) ◎ Back pressure Back pressure is the pressure of the outlet of valves. It increases the set pressure of proportional relief valves. RV and RM series: Balanced stem design to eliminate the effect of system back pressure RL series: Pre-set pressure = Desired pressure - 0.8 × Back pressure ◎ Working temperature: -10°F to 300°F (-23°C to 148°C) ◎ Variety of end connections ◎ Liquid or gas service ◎ Adjustable bonnet cap and adjustable set pressure ◎ Lead seal through lock wire holes to lock proportional relief valve so as to secure a set pressure effectively ◎ Variety of seal materials ◎ Label identifies the set pressure range
