2" Surpass Stainless Ball Valve 24 VDC, Safe Return

Valworx 591166 safe return 2-piece stainless steel ball valve features the Surpass actuator, our most advanced actuator yet. Upon loss of power the actuator fails closed (factory setting). The unit can also be set to fail open or a to a user-defined position. Actuator will not operate until restoration of power and receipt of a new control signal. Used for on-off control of water, air, oil, and other media compatible with the materials of construction.

The Surpass actuator can be programmed to operate in continuous mode (a signal pulse triggers continuous operation until full open or close) or inch mode (a signal pulse runs the motor for the duration of the pulse). Default is continuous mode.

Separate motor and control circuits for easier wiring and improved safety. Programmable end-of-stroke speed control to reduce/eliminate water hammer. Local control, capacitor state of charge and operating status via digital display.

The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad. Rugged unique integral motor/housing design provides higher torque in a very small package. Actuators are tested to rigorous UL and CSA standards and certified by CSA. Anti-condensation heater is standard and will help protect actuator against damage caused by condensation.

High temperature valve mounting kit available for extended temperature range or wall mounting applications.

Note: Factory setting is fail closed. For fail open or fail to position (x°) operation, specify in the comment section when ordering

Note: The safe return option returns the valve to a fail-safe position in the event of a loss of electrical power. It is not intended and should not be used for normal operation
