ValvTechnologies, Inc., manufacturer of zero-leakage severe service isolation valve solutions, has introduced a fast-acting, high-cycle NexTech® pulsejet valve with EcoPack™ stem packing solution for the reduction of fugitive emissions.
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.
ValvTechnologies’ pulsejet valve with EcoPack™ was tested at high pressure and line temperature to 450°F for over 500,000 cycles: lab results verified the solution not only met but 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. This equals longer plant operation between maintenance intervals, improved site safety, and less emissions from the stem packing.
