BURKERT 20016143 Type 7011 is a direct-acting and compact 2/2-way plunger valve designed for blocking, dosing, filling, and ventilating neutral gaseous and liquid media. The stopper and the core guide tube are welded together to increase pressure resistance and leak-tightness. This specific model features a 2.0 mm orifice, G1/8 internal thread, stainless steel body, EPDM seal, and operates on 24V DC. It utilizes a slipped-over coil system and provides a simple and fast mounting solution. When used in combination with a plug conforming to DIN EN 175301-803 shape B, the valve satisfies the IP65 degree of protection.

Installation and Operation

DANGER

Risk of injury due to high pressure in the system or device Before working on the system or device, switch off the pressure and ventilate and empty the lines.

Risk of injury from electric shock Before working on the system or device, switch off the power supply and secure against reactivation. Observe the applicable accident prevention and safety regulations for electrical devices.

Fluidic Connection

1. Check pipelines for soiling and clean if required.
2. Install a dirt trap to protect against disruptions (mesh width: 0.2...0.4 mm).
3. Note the flow direction. Letters on the body indicate the flow direction: CFB from 1(P) → 2(B).
4. Seal the pipeline with PTFE tape.
5. Hold the device on the body using an open-end wrench and screw into the pipeline. Do not use the solenoid as a lever arm.

Electrical Connection

WARNING

Risk of electric shock if protective conductor not connected Always connect the protective conductor. Check electrical continuity between the solenoid and the body.

1. Connect the protective conductor.
2. Attach seal and check that it fits properly.
3. Screw on the cable plug, observing maximum tightening torque of 0.3 Nm.
4. Check electrical passage.

Rotating the Coil

WARNING

Risk of injury due to overheating or fire hazard Connecting the coil without a pre-assembled armature will cause overheating and destroy the coil. Only connect the coil after the armature has been installed.

The solenoid can be rotated by 4 × 90° or 2 × 180° in case of a block installation.

1. Loosen the nut.
2. Rotate the solenoid.
3. Screw in the nut with an open-end wrench, observing maximum tightening torque of 2.8 Nm.
