1SE90 Series Counterbalance Cartridge Valve, 2537-5075 PSI (Factory Setting At 3045.00), Screw with Locknut Adjustment, 4:1 Pilot Ratio

Intended uses include refuse haulers. This valve has a maximum relief pressure of 5000 psi. Just be sure your system is running within that range.

Factory set at 3045 PSI, the adjustment range runs from 2537 up to 5075 PSI. The screw and locknut design lets you dial it in without pulling the whole unit. Just loosen the locknut, turn the screw to where you need it, and lock it back down. Worth noting that any pressure above 3000 PSI requires a steel housing, so make sure your setup accounts for that before pushing it toward the top of the range.

Built for load control, the 1SE90 counterbalance (overcenter) cartridge meters flow out of the actuator so the load cannot overrun the pump flow. When it’s close-coupled to the actuator, it also helps stop runaway in a hose burst situation, giving load holding and hose failure safety.
