Pneumatic Pressure Switch
V-Flow Solutions is able to offer a new range of pneumatic pressure switches.
The new switches offer a high-quality build and performance, with features such as being shock and vibration resistant to EN 61373 (Class B) and Corrosion resistant in accordance with salt mist test ISO 9227.
Below we detail the switch and its features and specifications.
Pneumatic Pressure Switch
The new pressure switch is designed specifically for withstanding shock and vibration in critical duties, usually found in the rail, commercial vehicle and industrial sectors.
The compact and lightweight electro-mechanical design delivers accurate, repeatable and reliable performance for multiple applications including compressors and braking systems in ambient working temperatures ranging from -40° to +85°C (-40°F to +185°F).
You can view the full specification sheet, for the pressure switches above, on our website.
