Designed for in-line mounting near the hydropneumatic product water tank
Automatically shuts off the booster pump when the tank is full
Normally closed switch – factory pre-set at various shut-off pressures
Ensures reliable operation of the hydraulic shut-off valve in typical under-counter RO systems
Compatible with 1/4" or 3/8" tubing via built-in John Guest half cartridges
For systems using both a permeate pump and a 6800 or 8800 series booster pump, or when shut-off pressure is above 40 PSI, an electronic shut-off valve (ESO) must be installed
Without an ESO at higher pressures, the system will not shut off properly and will continue running
Tip: Choose a shut-off switch based on your desired tank fill pressure.
Inexpensive and compact design
High reliability for consistent performance
100% factory tested
Integrated John Guest half cartridges for easy installation
