Transcription

1 2/2-way ball valve with electric rotary actuator, ball valve in stainless steel, Suitable for aggressive media High flow rate value -piece Actuator with adjustable limit switches 2-piece Visual position indicator Type 8804 can be combined with Type 2672 Metal butterfly valve Type 2675 Plastic butterfly valve Type 8804 Plastic ball valve The electric ball valve Type 8804 consists of an electrical rotary actuator and a 2/2-way or /2-way ball valve made of stainless steel. 2-way variants are available with a 2-piece or -piece ball valve for various applications. The -way version is offered with L or T bore holes (on request). The rotary actuator is compactly built. It can be used also as single device for the operation of other control members (see datasheet Type 00).
