Original parts
Hydrogen compliance to container and accessory inspections based on the High Pressure Gas Safety Law
■Simplified system with pressure reduction mechanism
■Domestically usable, compliance with KHK
■Specifications can be customized
■Domestic lightest-class 310g
Tank valves with pressure-reducing mechanism are compatible with hydrogen. It's largest input-pressure is 35MPa, output-pressure is 0.05～0.09MPa. It's weight 310g is as lightest as in Japan. It reduced weight by simplification of the system and conforms to the High Pressure Gas Safety Law. Flow rate switching, pressure gauge, safety valve, etc. are selectable as basic specifications and options. Trial production and sales have begun ahead of the launch.
Advantage of our valve system over conventional valve systems
System simplification
Conventional valve systems require several components like tank-tank-valve-steel pipe-pressure reducing valve-tube-FC stack. The valve system of NISSIN PREVO has a simple structure of tank-valves with pressure reducing-tube-FC stack. Integration of the pressure reducing mechanism into the valve eliminates the need to install a separate pressure reducing valve, and reduces the number of pipes and parts.
Realization of weight reduction
The simplified configuration of the entire system reduces weight and contributes to the reduction of vehicle and equipment weight. The valves themselves are also designed to be domestic lightest-class 310g, particularly suitable for mobility applications with hydrogen systems.
Hydrogen compatibility and legal compliance
It conforms to the Container Accessories Inspection based on the High Pressure Gas Safety Law, and the product design meets the safety standards.
This product conforms to KHK (The High Pressure Gas Safety Institute of Japan) and can be used domestically.
Customizable specifications
Output pressure can be selected when ordering within 0.05～0.09MPa.
Flow rate (20～50 L/min) can also be specified, and optimum setting can be made according to the application.
Flow rate switching function, pressure gauge and pressure relief valve can be added as options. It can meet a wide range of needs.
