Typical Installation of the E-Pro® Electric Valve Closure System

EPro 
                    installation

Optional Uninterruptible Power Supply is available.

*The image above shows the E-Pro actuators mounted on chorine ton containers. The actuators may also be used on 150 lb gas cylinders.  The system can be used on gas cylinders and containers of numerous hazardous gases.

System Components

Every component of the E-Pro® Electric Valve Closure System is engineered to be more versatile, efficient, and reliable than alternative units on the market. The System includes the actuator, control panel and mounting bracket.

E-Pro Actuator

Reversible

A push button on the end of the actuator makes it easy to re-open any non-leaking valve.

Durable

The actuator is constructed of aircraft-quality aluminum and high-grade carbon and stainless steels for maximum service life. Its housing is sealed to prevent intrusion from wind and water in outdoor applications. While a two-step polyurethane coating provides corrosion protection.

The E-Pro® System’s unique mounting mechanism, coupled with its lightweight, compact design, make it especially suited for horizontal application on 1-ton containers.

El Panel de Control

The E-Pro® Control Panel automatically activates the actuator to close the valve in the event of a gas leak, car movement, fire alarm, seismic event, security breach, process shutdown, or other monitored condition. You can also manually activate the system by depressing the emergency stop button on the panel.
