Electric Actuator
HOKE ® actuated valves are available for use in a wide variety of applications including on-off switching, selecting, sampling, and metering of fl uids. Specifi c types of actuated valves include 90° Shut-Off Ball Valves, 3-way, 4-way and 5-way Ball Valves and Metering Valves. Electrically actuated valves are supplied in two standard voltages, 115 VAC and 24 VDC, designed to be weather-proof standards. The Application / Buyers Guide will help you select the actuator-valve combination best suited to your requirements. Depend on HOKE ® to supply the actuated valve for your automated instrument and process systems, or for applications where manual control is diffi cult or not possible.
90° Actuators
