Maximator Air Actuated Hydrogen Needle Valve

Maximator H2 air actuated needle valves have been specially designed for hydrogen filling and testing applications and feature special dynamic sealing elements for a long service life.

The compact range for 1/4” tube is designed to conserve space whilst operating at 15,000 psi with low drive pressures. Both normally open and closed variants are available with the following specifications:

• Operating pressures of 15,200 psi (1,050 bar)
• Drive pressure of 4-8 bar
• Operating temperatures of -20℃ / +80℃
• Specially cleaned for use in hydrogen systems to avoid contamination.
• Designed with specific materials to avoid hydrogen embrittlement.

The intermediate range of hydrogen focused air actuated needle valves service both 1/4″ and 3/8″ tube, they are available in both normally open and normally closed variants with the option for an extended connection for low temperature applications ( -73℃).

• Operating pressures of 15,200 psi (1,050 bar)
• Drive pressures of 2-10bar
• Operating temperatures of -20℃ / +80℃ (-73℃ / +80℃)
• Specially cleaned for use in hydrogen systems to avoid contamination.
• Designed with specific materials to avoid hydrogen embrittlement.

The large range of hydrogen focused air actuated needle valves are designed for large tube applications from 9/16″ to 1″ in a normally closed configuration.

• Operating pressures of 15,200 psi (1,050 bar)
• Drive pressures of 5-10 bar
• Operating temperatures of -40℃ / +85℃
• Specially cleaned for use in hydrogen systems to avoid contamination.
• Designed with specific materials to avoid hydrogen embrittlement
