Description
The engine ball valve Type 8804 consists of an electric rotary drive and a 2/2- or 3/2-way ball valve made of stainless steel. As 2-way variants, two- or three-part housing designs are available for various applications. The 3-way ball cocks are available with L- and T-holes. The electric motor-driven rotary drive is built compactly. It can also be used as a single device for operating other actuators (see data sheet type 3003). Heating resistors and torque limiting are standard. The casing is made of flame-retardant material, classified according to UL94 V0.
