Product Description

TESCOM HV-3500 Series Two Stage Pressure Reducing Regulator is a reliable, low maintenance pressure control solution. This EC79-tested solution is specially designed for use onboard industrial and commercial medium and heavy-duty hydrogen fuel cell vehicles and allows manufacturers to maximize fuel efficiency and keep their fleet on the road for a longer distance. The HV-3500 also provides consistent pressure and continuous flow in a full range of operating conditions. It is suitable for nominal inlet pressures up to 35.0 MPa and can reach flow rates above 3.2 g H2/s.

Specifications

Nominal Inlet Service Pressure
5076 psi / 35.0 MPa / 350 Bar
Maximum Inlet Service Pressure
6345 psi / 43.8 MPa / 438 Bar
Minimum Inlet Pressure
290 psi / 2.0 MPa / 20.0 Bar
*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
Leakage
Bubble-tight
Operating Temperature
-40 °F TO +185 °F / -40 °C TO +85 °C
Flow Capacity
Cv 0.17
Decaying Inlet Characteristic
0.05 psi / 3.4 mbar per 100 psi / 6.9 bar 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.
