Emerson has introduced the TESCOMTM HV-7000 Series, a groundbreaking two-stage pressure-reducing regulator engineered to enhance fuel efficiency and reliability in heavy-duty vehicles powered by hydrogen fuel cells or combustion engines. This new regulator offers stable pressure delivery, high reliability, and extended service life by featuring two-stage pressure reduction and a positive seal design that ensures optimal pressure delivery to fuel cells under various flow conditions. The HV-7000 Series minimizes decaying inlet characteristics, provides superior shut-off performance, and reduces fueling costs while lowering the risk of downstream component failure and operational downtime. One of the primary causes of regulator failure, contamination, is addressed by the HV-7000's contamination-resistant features such as tied valve stems, integrated filters, and patented redundant seals. These elements prevent leakage, vehicle downtime, and potential safety hazards. The redundant seal design extends the regulator's cycle life, the integrated filter catches solid particles during installation to safeguard soft goods, and the tied valve stem counteracts contamination and wear on the seat. Moreover, in addition to benefiting vehicle users, the HV-7000 Series is designed to streamline assembly processes for fuel cell system manufacturers and integrators. Its compact, lightweight design with a flat shape and specific mounting holes enables easy integration into existing systems, reducing manufacturing costs, procurement time, and facilitating scalability as production volumes increase. Overall, Emerson's innovative regulator technology aims to optimize fuel efficiency, reliability, and overall performance in hydrogen-powered vehicles.
