MaxPro™ SG Pneumatic Valve Closure System
Avoid production slowdowns, 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 speciality 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
speciality 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. |
VERSATILE
Applicable to a variety of
valve designs and speciality
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. |
LOW MAINTENANCE
Robust motor requires minimal lubrication and
is completely encased by a steel cover for
protection and years of reliable service. |
PRECISE
Automatically responds to any alarm
input, instantly closing valves with
4.5 lb-ft of torque. |
DEPENDABLE
Mounts on the valve body
using the valve specific
adapter. Stops a reportable
release regardless of where
the leak occurs downstream. |
FAIL SAFE
Fail-closed design operates even
if AC power or air pressure is lost.
Requires 50 psig. |
MaxPro™ SG Pneumatic Valve Closure System is engineered, designed,
and field-tested to ensure reliable performance, while reducing installation time,
maintenance, and material cost.
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.
Durability
The actuator is constructed of aircraft-quality aluminum and highgrade
carbon and stainless steels for maximum service life. A twostep
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.
Maximum Control
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.
