New stem packing system for high-cycle valves

ValvTechnologies introduced the EcoPack™: a stem packing solution for high-cycle, fast acting valves that meets stringent fugitive emissions requirements. ValvTechnologies NexTech® pulsejet valve with EcoPack™ was recently tested by an independent agency that verified the solution not only met but exceeded endurance testing standard performed 500,000 cycles while retaining a maximum leakage rate equivalent to ISO 15848-1 2006 Class BH for the entirety of the test.
Typical stem sealing technology requires packing adjustment. With high-cycle valves, these adjustments would have to occur very often, causing disruptions in plant operation, safety concerns and non-compliance with tightening emissions regulations. With the EcoPack™ solution, lab tested results show the seal is capable of 500,000+ cycles with the stem packing requiring zero maintenance or adjustment. This solution is perfect for customers requiring a quickly-rotating valve that completes many cycles annually (i.e. 250,000 per year or more) and must also meet fugitive emissions requirements.
