BURKERT 352614 (Type 6026) is a direct-acting, media-separated 2/2-way plunger valve. The thermal and hermetic isolation of the coil and body by means of stainless steel bellows allows both extreme medium temperatures as well as aggressive media. This design avoids the build-up of condensation between the fluid part and coil or an unacceptable heating up or freezing of the coil. The coils are moulded with chemically resistant epoxy, making the valve particularly suitable for applications with critical media. The use of highly resistant body and seal materials such as stainless steel and PTFE make the valve suitable for critical chemical applications. To reduce power consumption in operation, coils with "Kick and Drop" (KD) electronics assembly (double coil technology) are available.

• Media-separated plunger valves up to DN12
• Suitable for high and low temperature ranges (-200 °C to +180 °C)
• Energy-saving double coil technology with Kick and Drop variant

Installation

Risk of injury from high pressure

Before loosening lines and valves, turn off the pressure and drain the lines.

Risk of injury from electric shock

Before reaching into the system, switch off the power supply and secure against reactivation. Observe any applicable accident prevention and safety regulations for electrical devices.

Fluidic Installation

• Installation position: any, preferably with solenoid or actuator facing upwards.
• Clean pipelines and flange connections.
• Install dirt trap at the valve inlet (0.2...0.4 mm).
• Note the flow direction of the valve. The arrow on the body indicates the flow direction.

Caution! Risk of breakage

Do not use the solenoid or actuator as a lever arm. Hold the valve body using a matching open-end wrench and screw into the pipeline.

Electrical Installation

• Observe the voltage and current type according to the type label.
• Check that the seal is properly fitted.
• Screw cable plug tightly onto the solenoid (max. 1 Nm).
• Always connect the protective conductor and check electrical continuity between solenoid and body.

Rotating the Solenoid

Risk of overheating and fire

Connecting the solenoid without a pre-installed valve will cause overheating and destroy the solenoid. Only connect the solenoid after the valve has been installed.

The solenoid can be rotated by 4 × 90°.

1. Loosen the nut.
2. Rotate the solenoid.
3. Use a matching open-end wrench to tighten the nut (max. 5 Nm).

Insulation

The device must not be insulated more than 2 cm from the body edge upwards to the actuator.
