Product Description

TESCOM HV-7000 Series Two Stage Pressure Reducing Regulator is a reliable, low maintenance pressure control solution specially designed for use onboard industrial and commercial heavy-duty hydrogen-powered vehicles with storage tanks rated up to 700 bar (10,150 psi). The HV-7000 helps maximize vehicle fuel efficiency by consistently delivering flows up to 5 g/s of hydrogen fuel at the right pressure needed by the fuel cell or hydrogen combustion engine across the full range of operating conditions. The contamination-resistant design of the HV-7000 ensures reliability and long service life, minimizing the vehicle cost of ownership.

Specifications

Nominal Inlet Service Pressure
700 bar / 10,153 psi
Maximum Inlet Rated Pressure
875 bar / 12,691 psi
Minimum Inlet Pressure
At least 150% of outlet pressure
*Operating at pressures below this minimum pressure could limit the maximum flow rate
Design Proof Pressure
150% of nominal inlet service pressure
Pressure Rating
Per Criteria of ANSI/ASME B31.3
Outlet Pressure Range
10-30 bar / 145-435 psi
Leakage
Bubble-tight
Operating Temperature
-40°F to +185°F / -40°C to +85°C
Flow Capacity
Cv=0.17; 5 g H2/sec
Decaying Inlet Characteristic
6.2 mbar per 6.9 bar change in inlet pressure / 0.09 psi per 100 psi change in inlet pressure
Filter
10 µm
*The 10 µm filter is for initial system assembly protection. The product is designed to be used with particulate free hydrogen. Your system should be designed with proper filtration before the regulator to protect against contamination.
