Our Pressure and Vacuum Switches (PSW and VSW Series) provide a full range of in-line pressure sensing electrical switches. These switches, typically mounted near a hydropneumatic holding tank, automatically control the system pump and/or solenoid valve as required. They can also be used to enable hydraulic shut-off valves to operate reliably and positively. Aquatec’s Pressure and Vacuum Switches are normally closed and can be pre-set at various shut-off pressures. If necessary, they can be adapted to operate as normally open switches through minor modifications to the wire terminal connector. The PSW/VSW Series also includes a modular connector for plug-and-play integration with Aquatec’s other system components.
