Type 6481 - Servo-assisted 2/2-way piston valve up to 450 bar
Type Description
The valve type 6481 is a servo-controlled piston valve for hydrogen applications up to a nominal diameter of 50 mm. A minimum differential pressure of 1 bar is required 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 is 5x 10-5 mbar l/s. On request, the push-over coil can be provided as a Zone 1 or Category 2 explosion-proof version.
- Hydrogen-resistant screwed fluid housing
- Function test with forming gas at nominal pressure
- Piston system with mechanical seal bearings
- Explosion-proof design ATEX and IECEx
- Inspection holes for monitoring the process seal
