GENERAL VALVE Aviation and
Military Fueling Solutions
High-integrity positive shut-off valves for the aviation and military fueling industry
GENERAL VALVE Solutions
INTRODUCTION
For more than 60 years, the GENERAL VALVE® Twin Seal™ valve has been the market
leader for double block-and-bleed plug valves. As the original pioneer, the design of the
valve established the standard specifications for high-integrity, positive shut-off valves. For
both in-line testing and simple field maintenance and repair, aviation fuel facility
managers, engineers and contractors rely on GENERAL VALVE Twin Seal valves for fuel
delivery with positive, provable segregation when leaks matter.
Our customers know that when they see the Cameron name, they can expect the highest
quality in engineering, manufacturing and customer support. That is why Cameron’s
GENERAL VALVE line can be found in airports and military installations around the world.
WHY GENERAL VALVE?
First, GENERAL VALVE Twin Seal and TruSeal™ valves hold a verifiable, bubble-tight,
fire-safe seal. Second, GENERAL VALVE valves offer more flexibility through the availability
of a broad range of sizes, materials, models and port configurations. The GENERAL VALVE
portfolio offers a wide range of products: the standard Twin Seal and TruSeal regular port,
Twin Seal full port, seat and reseat valves and the four-way diverter valve. Finally, all valves
within Cameron’s GENERAL VALVE product line have the important feature and
advantage of in-line repairability and are supported by Cameron’s global parts and service
network CAMSERV™ aftermarket services.
FEATURES
The original Twin Seal valve helped establish the
rigid requirements of double block-and-bleed
service and resulted in the market leading valve
we know today. The patented Twin Seal valve is a
non-lubricated, resilient seal, expanding plug-type
valve which has a mechanical means of freeing
the plug before it is rotated from the closed to
open position. The plug and seal slips rotate
freely, with no seal to body contact, eliminating
seal abrasion and wear. The unique, dove-tailed
design plug is operated inward between the slips,
mechanically wedging out the seal slips for a positive upstream and downstream shutoff.
This creates a positive, mechanical shutoff of each valve port independent of springs,
system pressure or flow. In addition, the primary seals are reinforced by a secondary
metal-to-metal seal, resulting in a superior, fire-safe design. Seals may be repaired with
common tools while the valve is in-line, after the line has been depressurized and drained.
Cameron’s GENERAL VALVE models can be easily adapted to accept electric or pneumatic
actuators. Actuators can be set to operate at various speeds with low torque
requirements. For high-speed applications, Cameron offers in-house designed and
manufactured hydraulic actuators and supporting power units.
TWIN SEAL – SEAT AND RESEAT VALVES
This is the GENERAL VALVE Twin Seal valve taken one step further. The seat and reseat
valve has all of the features of the Twin Seal with an additional capability – it can be
repaired or maintained using common hand tools without draining fuel out of the lines in
critical airside locations.
