Servo-assisted 2/2-way piston valve up to 1,000 bar – Type 6480

The valve type 6480 is a servo-controlled piston valve for hydrogen applications with a nominal diameter of 8 mm.

A minimum differential pressure of at least 5 bar is required in the valve to support the opening and closing process.

To increase the pressure resistance in contact with hydrogen, the plunger guiding tube and stopper are screwed together.

Only certified 3.1 materials suitable for hydrogen are used.

Each valve is subject to a functional test at maximum nominal pressure.

On request, the push-over coil can be provided as a zone 1 or category 2 explosion-proof version.

Key Features

Mechanical line connection: Threaded G3/8, UNF 13/16-16

Nominal width: 8 mm

Versions: NC, 2-way

Pressure range: 5 to 1,000 bar (depending on version)

Leakage rate at nominal pressure: 5x 10^-5 mbar l/s.

Long service life of more than 80,000 switching operations

Medium temperature range: -40 to +80 °C

Protection class: IP65

Optional approvals/conformities: Hydrogen suitability, ISO 19880-3, Pressure Equipment Directive 2014/68/EU Category IV
