BURKERT 20068749 Type 5282 is a servo-assisted 2/2-way diaphragm solenoid valve. A minimum differential pressure is required for the valve to function. The standard brass body satisfies all European drinking water requirements. The 3/2-way pilot valve can be easily converted from NC to NO circuit function by rotating it on the armature. The solenoid coils are moulded with a chemically resistant epoxy. The 5282 is equipped with a manual override for start-up and testing.

Product Installation

Safety Instructions

• 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.

Mounting Options

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.

Setting the Switching Times

The closing and opening times of the valve can be changed if required with the side throttle screws.

Pressure Surges

If closing times are fairly short, liquid media cause higher pressure surges. These may reduce the service life of the diaphragm and destroy other devices and components in the system. Discharge of medium occurs if the throttle screws are unscrewed too far.

Maintenance and Troubleshooting

Malfunction	Possible Cause
Valve does not switch	Short-circuit or coil interrupted
	Medium pressure outside the permitted pressure range
	Manual emergency actuation locked
Valve does not close	Internal space of the valve is dirty
	Manual emergency actuation locked
