Pressure Switch – Adjustable Deadband
Potter Flow
- The model PCS is an Adjustable Deadband Pressure Switch with independent set and reset points which are adjustable throughout the entire operating range of the switch
- The minimum deadband (minimum span between set and reset points) may be obtained at any point in the operating range of the switch
- A change in pressure greater than the high setting will reposition the switch mechanism to open or close a single snap-action electrical switch
- This control device is designed for use as an operating control in applications sensing air, water, or any fluid not harmful to the pressure connection, diaphragm or nitrile pressure-sealing o-ring.
- Where an operating control would result in personal injury and-or loss of property, it is the responsibility of the installer to add devices (safety, limit controls) that protect against, or systems (alarm, supervisory systems) that warn of control failure
- Not intended for applications in explosive environments or use with hazardous fluids
- Adjustable Pressure Switch
- Minimum deadband: 12 PSIG
- Proof pressure: 400 PSIG
- Factory setting: 90/60 PSIG

Switch – Flow, CPVC
- The Model VSR-SFT is a vane type waterflow switch for use on wet sprinkler systems that use 1”, 1-1/4”, 1-1/2” pip size
- It is equipped with a union to accommodate installation in confined spaces
- Contains two single pole double throw snap action switches and an adjustable, instantly recycling pneumatic retard
- The switches are actuated when a flow of 8-10 gallons per minute (30-38 liters per minute) or more occurs downstream of the device
- The flow condition must exist for a period of time necessary to overcome the selected retard period
- For 1” to 2” CPVC pipe sizes with NEMA 4 enclosure indoor & outdoor use, service pressure to 175 PSI
