Manual Type

The answer to problems of: corrosion, abrasion, clogging, contamination, vacuum & gas handling

The most common and traditional type. The valves are large to accommodate the yoke and stem mechanism, but fully open the full bore design provides an uninterrupted flow path.
Generally either used fully open or closed, for on/off isolation, and not used for modulating flow control duties.
Variants include Solid and Flexible Wedge Gates, Double Disc Gates, Through Conduit Valves, Parallel Slide Valves and Knife Gate Valves.

PERFORMANCE FEATURES

• Valves with most advanced designing features provide the ultimate in dependable, economic flow control
• Surface protection for Carbon steel Valves, Chlorine free prime coat with modified alkyd resin unobjectionable in physiological and toxicological respects. Additional external coating: Silver Streak aluminum paint/varnish light blue

G&O SERIES PNEUMATIC ACTUATORS

Piston type air operators line offer a great solution to a wide range of actuation situations. They are exclusively designed to G&O series butterfly valves and can be mounted in any position. These actuators are built in aluminum and are available in three options:
• single effect acting – fail to close (air to open)
• single effect acting – fail to open (air to close)
• double effect acting – fail to open & fail to close
Single effect acting actuators are fitted by an extractable handwheel for security.
