Powell E-Pro® Electric Valve Closure System vs. Other Electric Shutdown Systems

Powell is the only valve closure manufacturer to offer both an electric system and a pneumatic system for small containers such as 150 lb gas cylinders and ton containers.

E-Pro Electric Valve Closure SystemThe Powell E-Pro® Electric Valve Closure System uses standard 120-volt AC power. It is ideal for plants or remote facilities that do not have compressed air or nitrogen required by pneumatic systems. Unlike battery-powered units, you do not have to worry about system failure when the batteries discharge. Designed for both 1-ton and 150-lb containers, the E-Pro's unique mounting bracket easily attaches and detaches from the valve stem in seconds, without tools.

Ten Reasons to Choose the E-Pro Valve Closure System Over Other Electric Systems

Feature E-Pro System Other Electric Systems
Actuator mounts on the valve, not on the yoke where activation can actually cause a leak. Y N
Plant power will operate the system if the batteries run down. Y N
No need to replace the batteries yearly. Y N
The power cord is easily removable from the actuator to facilitate easy storage. Y N
The valve can be opened electrically from the actuator, with no delicate clutch to engage or break. Y N
The actuator can be tested at full power on the valve. No need for a low torque test mode. Y N
The actuator uses 110 volt electrical power, not a 12 volt motorcycle battery. Y N
The control panel is listed by Underwriters Laboratory. Y N
The control panel is built using electrical components readily available at any electrical supply. Y N
The system is part of a family of valve closures designed to close valves on everything from 150 lb cylinders to 90 ton tank cars. Y N

 E-Pro® system components include the actuator, control panel and mounting bracket. Optional system components include the Remote Emergency Stop Pushbutton Panel (E-Stop Panel) and Uninterruptable Power Supply.  E-Pro Emergency Valve Closure System
