When specifying Emergency Valves for your vehicle the following points should be considered:
- Pneumatic equipment to operate the emergency valve.
- Inlet and outlet flange gaskets to suit the chosen valve.
- Quantity required per vehicle.
- Remember to specify the F0019 Bottom Operator and the F0028 Cable Assemblies to suit if selecting a Mechanical Valve.
- Consider how many compartments are being catered for, and which sealing material is required?
