Series 2/975

Valves for high-pressure storage tank technology, including for the peripherals for refuelling fuel cell vehicles. 2/2-way seat valve with pneumatic NC drive, closing with spring force. The field of application of the valve type 2/975 is versatile, as a refuelling/safety shut-off valve for gaseous H2 up to liquid methanol, to name just two of the most common media. With/without labelling for explosion-proof atmosphere. The valve is controlled with at least 6 bar control pressure. An electrical position indicator is possible on request and can be integrated into the control system.
