Hydrogen fuel cell pressure regulator - LW351

The LW351 is a piston-sensed pressure regulator, designed specifically for drone and lightweight hydrogen fuel cell applications

With a low 0.15% decaying pressure effect, it offers accurate control in a single-stage pressure reduction.

When weight is a critical consideration for your application, the LW351 is the perfect solution.

It's compact size and lightweight design (down to 0.2kg) fits the bill, and additionally offers direct mounting to the Hydrogen cylinder

Key components

Key components of the LW351 and its materials are listed as below:

Body and Bonnet: Material used is Aluminium T6511 (UNS AW6082). Suitable to use at approx. temperatures -196°C to 200°C

Main Valve Pin: Material used is ASTM A479 316/316L Stainless Steel (UNS S31600/S31603). Suitable to use at approx. temperatures -196°C to 538°C

Valve Spring: Material used is Inconel® X750 (UNS N07750). Suitable to use at approx. temperatures -196°C to 700°C

Piston: Material used is Aluminium T6511 (UNS AW6082)

O-Rings: Material used is FKM/FPM (Viton). Suitable to use at approx. temperatures -20°C to 200°C

Loading Spring: Material used is AISI 17-7 PH Stainless Steel (UNS S17700)

Filter: Filter is made up of 40 Microns

Seat: PCTFE (Kel-F). Suitable to use at approx. temperatures -196°C to 180°C

Benefits

Product features is correlated with the advantages of products as listed below:

Lightweight and Compact: Weighs as little as 200g- perfect if application would benefit from a lightweight solution..

Piston Sensing Element: Perfect for use in challenging conditions.

0.15% Decaying Pressure Effect: For stable pressure control, even under depleting gas supply conditions.

Direct Mounting to Cylinder: Quick and convenient design.
