The SUN SXEALBN is a solenoid‑operated relief valve that provides on/off pressure limiting function, ideal for safety shut‑off or dual‑pressure systems. When energised, the solenoid opens a pilot passage to set the relief pressure; when de‑energised, the valve acts as a standard relief. This flexibility simplifies circuit design and enables remote activation of different pressure levels.

The SXEALBN combines a conventional Relief valve with a direct‑acting solenoid pilot, offering a compact solution for electrically controlled pressure limiting. In its de‑energised state, the valve operates as a standard adjustable relief valve with a preset pressure. When the solenoid is energised, the pilot port is opened, reducing the effective relief setting to a lower value – perfect for systems requiring two distinct pressure thresholds, such as high‑pressure working mode and low‑pressure idle mode. The solenoid is designed for 12 V or 24 V DC operation, with optional manual override for emergency use. Maximum system pressure is 350 bar, with flow capacity up to 60 L/min. The valve body is constructed from ductile iron with a corrosion‑resistant coating, suitable for both mobile and stationary applications. Seals are available in various materials to match different hydraulic fluids. The SXEALBN also features a built‑in surge suppression diode to protect the electrical system. Typical applications include hydraulic shears, clamping units, and circuits requiring rapid pressure changeover. Its fail‑safe design ensures that in case of power loss, the valve reverts to the default relief setting, maintaining system safety.
