Diaphragm Actuated Safety Shutdown Valve

Diaphragm Actuated Safety Shutdown Valve Assembly

 

Quality and Dependable Diaphragm Actuated
Safety Shutdown Valve Assembly

 

Technically superior and affordable priced safety shutdown valve –

APPLICATIONS:

  • Surface wellheads
  • Flowlines
  • Headers
  • Pipeline Systems
  • Casing-relief blowdown valve applications

FEATURES:

Available Valve Sizes:

  • 2 – 1/6 in. 5,000 psi
  • 2 – 9/16 in. 5,000 psi
  • 3 – 1/8 in. 5,000 psi
  • 1 – 13/16 in. 10,000 psi
  • 2 – 1/16 in. 10,000 psi

BENEFITS:

  • Less Maintenance – A rolling nylon reinforced diaphragm design eliminates moving O-ring seals and leads to longer seal life.
  • Proven reliability – API 6A PR2 Appendix F qualified packing.
  • Lightweight – Easy to install and maintain. Can be redressed without special tools or external pressure sources.
  • Quick disconnect – Actuator can be removed from the valve without the use of special tools or an external pressure source.
  • Large diaphragm area – Allow the use of Low Pressure air or gas control systems. A relief valve on the cylinder acts to protect against damage to the diaphragm in case of excessive pressure increase.

Natural Gas for Our Future
Natural Gas an ideal fuel source for many reasons, including safety. Natural Gas is lighter than air. This means that it will not puddle (like gasoline) or sink to the ground like propane, which is heavier than air. Instead, Natural Gas will rise and dissipate in the atmosphere. Natural gas also has a higher ignition temperature. This means that it is much harder to ignite. Also the storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today.
