AAK is posting new Hydraulic Relief Valves equivalent to SUN RPEC8, RPGC8,

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.
