Bürkert Type 5282 (Model 364437) is a servo-assisted 2/2-way diaphragm solenoid valve designed for controlling, shutting off, and metering neutral and aggressive media. This specific model features a stainless steel flange body (DIN EN 1092-1), FKM (Fluor rubber) seals, and operates on 24V DC. It requires a minimum differential pressure of 0.2 bar to function and supports a pressure range up to 12 bar. The valve is equipped with a service-friendly manual override for start-up and testing, and its separating diaphragm makes it highly suitable for contaminated or aggressive fluids.

Installation and Operation

Risk of injury from high pressure

Before loosening the pipes and valves, turn off the pressure and vent the pipes.

Risk of injury due to electrical shock

Before reaching into the device or the equipment, switch off the power supply and secure to prevent reactivation. Observe applicable accident prevention and safety regulations for electrical equipment.

Manual emergency actuation

TIP

When the manual emergency actuation is locked, the valve can no longer be actuated electrically.

Changing valve function The delivery condition corresponds to the order key. Turning the pilot valve through 180° changes the circuit function of the valve. The circuit function can only be changed for variants up to 10 bar.
