He paddle valve switch Allows users to control air inflation and deflation through the movement of a handle up o down, thus enabling the lifting, pressure regulation and position adjustment of pneumatic springs, air-cushioned seats or suspension systems.
1. How it works:
The pneumatic switch is built into the manual paddle valve, and moving the paddle up or down will controls opening and closing of the compressor relay.
This switch regulates the air flow from the air tank (or compressor) towards suspension bag or the pneumatic seat device. The average filling time of the bag is 8 to 12 seconds, which depends on the size of the air tank and the maximum pressure (PSI) that it contains.
2. Features:
- Valves for controlling truck seats with Pneumatic suspension y lumbar supports.
- Three-way function with spring return.
- Electro-pneumatic combination valve designed to operate pneumatic seats using an electric air compressor.
- Designed to replace seat valves manufactured by major manufacturers such as Bostrom, National y Sears.
