| Message: | AAK is posting new Hydraulic Relief Valves equivalent to SUN RPEC8, RPGC8, RPIC8, RPKC8 series
Today, we’d like to introduce a series of hydraulic relief valve, equivalent to SUN RPEC8, RPGC8, RPIC8, RPKC8 series.
These valves are normally closed modulating elements that incorporate an integral pilot control cavity. They are balanced piston design.
The RPEC8, RPGC8, RPIC8, RPKC8 pilot control cavity will accept any T-8A pressure control cartridge. When the pressure at the inlet (port 1) reaches the pilot control cartridge’s setting, the modulating element starts to open to tank (port 2), throttling flow to regulate the pressure. The pilot cartridge’s setting determines the difference in pressure between port 1 and port 2. With the -8 control option, the main stage valve should first be installed to the correct torque value. The T-8A pilot control valve should then be installed into the main stage valve to its required torque value.
Technical parameters of AAK E-RPEC8, E-RPGC8, E-RPIC8, E-RPKC8 Hydraulic Relief Valves:
Max.Operating Pressue: 350 bar (5000 psi)
Capacity: 95 L/min (25 gpm); 200 L/min (50 gpm); 380 L/min (100 gpm); 760 L/min (200 gpm)
Control Pilot Flow:
0,11 - 0,16 L/min.; 0,16 - 0,25 L/min.; 0,25 - 0,33 L/min.; 0,25 - 0,33 L/min.,
Pilot Control Cavity: T-8A
Maximum Valve Leakage at 110 SUS (24 cSt):
32,8 cc/min.at 70 bar; 49,2 cc/min.at 70 bar; 65,5 cc/min.at 70 bar; 81,9 cc/min.at 70 bar;
Temperature: - 40°C ~ +120 °C
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus)
Cavity: T-10A; T-3A; T-16A; T-18A
AAK hydraulic Pilot-Operated, Balanced piston relief main stage with integral T-8A control cavity, benchmarking SUN RPEC8, RPGC8, RPIC8, RPKC8 series, the service life is 2 times of other hydraulic cartridge valve manufacturers in China. You are welcome to try it out.
