3/8" Explosion Proof Brass Ball Valve 110 VAC, EPS Positioner

Description

Valworx 583203 explosion proof lead free brass ball valve is used for positioning control of water, air, oil, and other media compatible with the materials of construction. Ideal where lead free and NSF construction are required for potable drinking water as well as other industrial applications. The EPS- Electronic Positioning System provides an accurate valve positioning function whereby the movement of the actuator is controlled by a 4-20mA input control signal. Any change in the input signal results in a corresponding and proportional change in the position of the ball. The internal microprocessor and closed loop feedback system continuously monitors and maintains accurate valve position. Valve can be set to fail closed, in-place or open with loss of control signal. The valve will remain in the last known position with loss of electric power.

The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad. Valworx does not recommend the use of high temperature brackets with explosion proof actuators. Rugged unique integral motor/housing design provides higher torque in a very small package. Actuators certified for UL Class I Div I Groups C & D, and are tested to rigorous UL and CSA standards and certified by CSA.
