U.S. Patent 6,840,503

Stop Dangerous Leaks of Extremely Hazardous Gases Where They Occur
Some valve closure systems are simply built. Ours are engineered.

​

PNEUMATIC

Ideal for applications where air or nitrogen is readily available. Fail-closed design operates even if AC power or air pressure is lost. Requires 90 psig.

​

EASY TO INSTALL

Applicable to a variety of valve designs and hazardous chemicals, the system has a unique mounting bracket that can be mated to any of several available valve adapters. For use on containers of chlorine*, sulfur dioxide, anhydrous ammonia, liquid hydrogen chloride, and other pressurized hazardous gases. Also accommodates vacuum regulators (chlorinators).

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

​

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, resulting in a dangerous leak.

​

POWERFUL

Automatically responds to any alarm input, instantly closing valves with 40 lb-ft of torque.

VERSATILE

Applicable to a variety of valve designs and hazardous chemicals, the system has a unique mounting bracket that can be mated to any of several available valve adapters. For use on containers of chlorine*, sulfur dioxide, anhydrous ammonia, liquid hydrogen chloride, and other pressurized hazardous gases. Also accommodates vacuum regulators (chlorinators).

​

LIGHTWEIGHT & COMPACT

Only 5.5 pounds. Exclusive “Right-Angle” (RA) design allows manual valve operation with a standard wrench. Also minimizes length when installed, extending no more than 4 inches beyond the rim of a 1-ton container.

LOW MAINTENANCE

​

Robust motor requires no lubrication and is completely encased by a steel cover for protection and years of reliable service.

​

MaxPro RA
The MaxPro™ RA Pneumatic Valve Closure System has been engineered, designed, and field-tested to ensure reliable performance, while reducing installation time, maintenance, and material cost.

That’s Reliable Engineering.

​

MaxPro ™ RA System Components

​

Every component of the MaxPro™ RA Pneumatic Closure System is engineered to be more versatile, efficient, and reliable than other units on the market. The system includes the following: actuator, air supply hose, mounting bracket, control panel, air control unit, air receiver tank, uninterruptible power supply, remote e-stop, and chlorine wrench.

​

Designed for Versatility

This patented design consists of a pneumatic drive with a spring-loaded coupler designed to accommodate valve stems of varying lengths.

​

Durability

The actuator is constructed of aircraft-quality aluminum and high-grade carbon and stainless steels for maximum service life. A two-step polyurethane coating provides additional corrosion protection.

UniPro Control Panel

 

Maximum Control

The MaxPro™ RA Control Panel automatically activates the actuator to close the valve in the event of an accidental release, 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. A single control panel can activate up to eight container-mounted actuators to close all eight valves — simultaneously.

The included 6-foot air supply hose has a safety swing coupling to ensure a secure connection between actuator and gas supply, while helping to prevent kinks or tangles in the hose.

The air control unit supplies the proper amount of clean, pressurized air to the system.
