Stop Dangerous Leaks of Extremely Hazardous Gases Where They Occur

E-Pro Electric Valve Closure System (shown on 1-Ton Container for Extremely Hazardous Gases) Avoid production slowdowns, operator injury, or lengthy and expensive environmental cleanups by preventing dangerous chemical leaks with the E-Pro^® Electric Valve Closure System. Designed for both 1-ton containers and 150-lb cylinders, this patent-pending emergency valve closure system prevents reportable releases of pressurized hazardous gases at the source. Improve your Risk Management Planning (RMP) scenarios with an electric-powered system that not only promises convenient and easy installation, but also superior performance and reliability.

Some valve closure systems are simply built.
Ours is engineered.

ELECTRIC

Uses standard 120-volt AC power. Ideal for smaller plants or remote facilities that don’t have compressed air or nitrogen required by pneumatic systems. Unlike battery-powered units, you don’t have to worry about system failure when the batteries discharge.

EASY TO INSTALL

Designed for both 1-ton and 150-lb containers. Unique mounting bracket easily attaches and detaches from the valve stem in seconds, without tools.

DEPENDABLE

Mounts on the valve body, not the yoke. This prevents any torque from being transferred to the yoke, which could cause the lead gasket between the yoke and container valve to fail, causing a leak.

POWERFUL

Automatically responds to any alarm input, closing valves with 40 lb-ft of torque in less than 5 seconds.

Patent Pending

VERSATILE

Applicable to a variety of valve designs and hazardous chemicals, including containers of chlorine*, sulfur dioxide, ammonia, and liquid hydrogen chloride. Also accommodates vacuum regulators (chlorinators).

*Designed in accordance with The Chlorine Institute’s guidelines for valve closure systems.

LIGHTWEIGHT

Only 8.5 pounds – makes handling the system safer and easier. Also reduces cantilever stresses when mounted horizontally on 1-ton containers.

ADAPTABLE

The unique, new mounting bracket can be mated to any of several available valve adapters - allowing the system to be used on valves for containers of chlorine, sulfur dioxide, anhydrous ammonia and liquid hydrogen chloride.

Designed and field-tested, the E-Pro^® Electric Valve Closure System was two years in the making.
The result: A unique system that delivers superior performance, durability and reliability.

That’s Reliable Engineering.

System Components

E-Pro Electric Valve Closure System - Actuator 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.

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.

Maximum Control

Control Panel for use with the Powell E-Pro Electric Valve Closure System

The E-Pro^® Control Panel automatically activates the actuator to close the valve in the event of a gas leak, 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. Control panels are available in single, double, and quad models for activating one, two, or four actuators.
