EcoPack valve technology reduces fugitive emissions for pulsejet valves

HOUSTON -- Reducing fugitive emissions is a leading concern in the fight against climate change. The EPA estimates that the production segment of the oil and natural gas industry is responsible for 45% of total methane emissions. Because valve leakage is responsible for more than 50% of total fugitive emissions, valves have been a considerable focus in the effort to reduce fugitive emissions.

To meet stringent fugitive emissions requirements, ValvTechnologies has introduced pulsejet valve with EcoPack™ technology: a superior stem packing solution for high-cycle, fast-acting valves. Pulsejet valves are designed to send a pulse of gas through a pipeline system. A trunnion-mounted ball valve, ValvTechnologies NexTech® pulsejet valve is 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.

A pulsejet valve with EcoPack™ technology was recently tested at high pressure and line temperature to 450°F for over 500,000 cycles: lab results verified the solution exceeded endurance testing standard performed while retaining a maximum leakage rate equivalent to ISO 15848-1 2006 Class BH for the entirety of the test, requiring zero adjustments or maintenance.


Emissions from non-OECD countries are increasing through 2040, while CO2 emissions from OECD member countries remain relatively flat.
