Watts also offers a full line of actuation accessories, such assolenoid valves, valve positioners, position indicating switches, and speed control valves to meet a varietyof actuation requirements.Pneumatic ActuatorReversing Electric ActuatorElectric Actuator7

Butterfly Valve Actuation Data SheetIn order to provide properly sized butterfly valve and actuator units to meet specific applications, it is important that Watts beprovided as much of the following data as possible. Please note that Watts provides the following standard featureswith its actuators.1. A motor brake as standard with electric actuators to prevent hunting of the butterfly disc at the desired disc position.2. Pneumatic actuators sized at 80 psi air supply pressure. Consult Watts when using an air supply of less than 80 psi.3. Solenoid valves mounted directly to the pneumatic actuator housing when ordered with Watts pneumatic actuators.1. Valve Information:A.
