Table of Contents

The Burkert Type 6221 Pistonvalves are based on a modular concept comprising three basic elements: Valve assembly, push-over coil and standard cable plug.

Burkert Type 6221 Piston valve is specificly designed for general purpose applications with air. The design principle of this valve allows high pulsed operations in air pipe runs, where other general purpose valves cannot be used, as they start to vibrate quickly. So life-time of this valve could be substantially increased, compared to other solutions.

A minimal pressure differential of 1bar is required for complete opening.

To simplify ordering, a wide selection of standard combinations of valve body, push-over coil and standard cable plug can be ordered with one order number. Cable plug options of Type 2508 are available to suit special electrical application requirements. – The modular concept provides flexibility to meet application requirements.
