Servo-assisted 2/2-way piston valve up to 1000 bar

Model: Type 6480

Booth No: N/A

Characteristic

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. Certified 3.1 materials suitable for hydrogen and carbon-coated magnetic steels are used. Each valve is subject to a functional test at maximum nominal pressure. The external leakage at nominal pressure is 5 x 10-5 mbar l/s. On request, the push-over coil can be provided as a zone 1 or category 2 explosion-proof variant.

- Hydrogen-resistant screwed valve body
- Function test with forming gas at nominal pressure
- Piston system with mechanical seal bearings
- Explosion-proof variant ATEX and IECEx
- Inspection holes for monitoring the process seal
