8804 Plastic Electric Rotary Actuator
Brand: Burkert Fluid Control SystemsThe electric ball valve Type 8804 consists of an electrical rotary actuator and a 2/2 or 3/2-way ball valve made of plastic. Different housings and materials are available for various applications.
The rotary actuator is compactly built. It can be used also as single device for the operation of other control elements.
Features- The ball valves are equipped with the so called dual block technology. This system allows you to lock the union nuts in the preset position. It prevents them separating during operation
- Heat resistor and torque limiter are standard. The body is made of low inflammable material, classified according to UL 94 V0
