Burkert Type 5282 (SKU 20068772) is a servo-assisted 2/2-way diaphragm valve designed to control, shut off, and meter neutral media. A minimum differential pressure is required for the valve to function. The solenoid coils are moulded with a chemically resistant epoxy, and the valve is equipped with a service-friendly manual override for start-up and testing.

This specific model features a stainless steel body, FKM seals, and an NPT 1/2 threaded connection. It operates at 120 V (60 Hz) and handles media temperatures from 0 °C to +90 °C and pressures from 0.2 to 12 bar. The 3/2-way pilot valve can be easily converted from NC to NO circuit function by rotating it on the armature.

Circuit Functions

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

• Circuit function A (CF A): 2/2-way solenoid valve, servo-controlled, normally closed.
• Circuit function B (CF B): 2/2-way solenoid valve, servo-controlled, normally open.

Installation and Operation

WARNING

Risk of injury from high pressure in the equipment. Before loosening the pipes and valves, turn off the pressure and vent the pipes.

Manual Emergency Actuation

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

Changing Valve Function

The 3/2-way pilot valve can be converted from NC to NO circuit function by rotating it on the armature.

DANGER

Discharge of medium due to leaking device. If the O-rings are forgotten or incorrectly inserted during installation of the pilot valve, the device will be damaged and medium will be discharged. Before screwing in the pilot valve, correctly insert O-rings into the depressions.

Setting the Switching Times

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

TIP

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.
