Product Focus: PulseJet Valves

ValvTechnologies’ Specialty Products - Reduce Fugitive EmissionsPulseJet
ValvTechnologies’ pulsejet valve is a fast-acting, high-cycle fugitive emissions valve designed to send a pulse of gas through a pipeline system. A trunnion-mounted ball valve, capable of 90° or 180° rotation
in speeds as low as 0.5 seconds or faster, this fast actuation speed is what creates the gas “pulse”
through the pipeline system. PulseJet systems can be used to clean system filters, spray chemicals in an
injection type system, or pulse debris/media through a pipeline to prevent clogging.

ValvTechnologies is the leader in fast-acting, high-cycle, fugitive emissions valves. This technology is
unmatched in the industry.

Key Design Features and Benefits 
These systems cycle many thousands of times per day. Conventional packing systems cannot handle the abuse of the fast cycle speed combined with the high cycle count. ValvTechnologies’ EcoPack® solution was designed to address this challenge. The EcoPack® seal has been lab-tested at high pressure and line temperature to 450°F for over 500,000 cycles, requiring zero adjustments or maintenance. This equals longer plant operation between maintenance intervals, improved site safety, and less emissions from the stem packing.

   • Guaranteed tight shut-off
   • True metal-to-metal sealing without using secondary elastomeric seals
   • Two piece, split-body design

   • Double block-and-bleed capability
   • High-cycling capability
   • Bi-directional sealing by design
   • Single-piece anti blow-out stem design
   • Impervious to high thermal cycling
   • Live-load stem packing (four-bolt design)
   • Stem fugitive emissions per ISO 15848-1 Class B
   • Fire safe certification: API-607
   • Meets ISO-15848-1 testing requirements for fugitive emissions
   • Packing requires zero adjustment or maintenance
   • Capable of 500,000+ cycles
   • Durable packing solution for extremely fast cycle speeds of less than 0.5 seconds
