MaxPro™ SG Pneumatic Valve Closure System
Avoid production slow downs, operator injury, or lengthy and expensive environmental
cleanups by stopping dangerous chemical leaks with the MaxPro™ SG Pneumatic Valve
Closure System. Designed for tube trailers and specialty gas cylinders, this patent-pending
emergency valve closure system prevents reportable releases of pressurized hazardous
gases commonly used in agricultural applications and electric, solar, and other
industries using specialty type gases. Add an additional layer of protection with
a pneumatic powered system that not only promises easy installation and low maintenance,
but also superior performance and reliability.
EASY TO INSTALL
Designed for tube trailers, cylinders, and ton containers. Unique mounting bracket
easily attaches and detaches from the valve stem in seconds, without tools.
Applicable to a variety of valve designs and specialty gases, the system has a unique
mounting bracket that can be mated to any of several available valve adapters. For
use on anhydrous hydrogen chloride, dichlorosaline, trichlorosaline, silicon tetrachloride,
and other pressurized hazardous gases.
Robust motor requires minimal lubrication and is completely encased by a steel cover
for protection and years of reliable service.
Automatically responds to any alarm input, instantly closing valves with 4.5 lb-ft
Mounts on the valve body using the valve specific adapter. Stops a reportable release
regardless of where the leak occurs downstream.
Fail-closed design operates even if AC power or air pressure is lost. Requires 50
MaxPro™ SG Pneumatic Valve Closure System is engineered, designed, and field-tested
to ensure reliable performance, while reducing installation time, maintenance, and
Every component of the MaxPro™ SG Pneumatic Valve Closure System is engineered
to be more versatile, efficient, and reliable than alternative units on the market.
The system includes the actuator, air control unit, control panel, mounting bracket,
and air supply hose.
Designed for Versatility
This patent-pending design consists of a pneumatic drive with a spring-loaded coupler
to accommodate valve stems of varying lengths and handwheel designs.
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.
The 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 length of the air supply hose assembly is custom made at time of order.
The MaxPro™ SG 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, power loss, or other monitored
conditions. By shutting down the flow of the product at the source, the release
is stopped regardless of where it occurs downstream. You can also manually activate
the system by depressing the emergency stop button on the panel.
