This series has a relatively high closing force and is therefore used in applications where control of high-pressure lines (up to 10 bar at both ends) is required.

The DISASTER 025 with the integrated accessory interface is also a good choice if simple system integration is important.

Available operating modes: FC, FO, and DA.

Advantages of DISASTER 025 pneumatic diaphragm valve:

● Extensive selection of materials

● A wide range of application fields

● Corrosion resistance

● Security

● Safe maintenance and short downtime

● Simple integration of multiple accessories

● Smaller inventory and faster turnaround

DISASTER 025 types pneumatic diaphragm valve optional:

Normally closed (FC mode)

closes the valve by spring force in the non-operating state. The valve opens when the actuator is pressurized by the control medium (lower connection). When the control medium is discharged, the valve is closed by spring force.

Normally Open (FO Mode)

In the non-operating state, the valve is opened by spring force. The valve closes when the actuator is pressurized by the control medium (upper connection). When the control medium is discharged, the valve is opened by the spring force.

Double-acting (DA mode)

valves do not have a defined base position. Valves are opened and closed by applying control pressure to the corresponding ports. (The upper part is turned on and off, and the lower part is turned on and off)
