Backflow preventer and Autofill Combination with Pressure Gauge (Commercial Applications)

The 5350 series AutoFill™ automatic filling valve is a pressure reducing valve which when installed on the water inlet piping in closed hydronic systems will maintain system pressure at a set value, automatically filling up with water as required. It fast fills the system to set pressure then automatically shuts off the water feed. This product is factory pre-set to 15 psi system pressure. To adjust the set pressure, simply turn the
adjustment knob while observing the integral downstream pressure gauge.

This product has the characteristic of being pre-adjustable, which means that it can be adjusted at the right pressure value before the system charging phase. After installation, the system pressure will automatically adjust itself to the set value and the water feed will stop when the set pressure is reached.

The internal cartridge containing all the controlling components is pre-assembled as a self-contained unit, to facilitate inspection and maintenance procedures.

The 5350 series is available with conventional union NPT and union sweat connections and the Presscon™ press copper tail-piece with union nut makes installation and maintenance fast, easy and efficient.

Special slots in the EPDM O-ring allows fluid to leak during system testing if unpressed and provide a perfect leak proof seal when completely pressed.

Complete with integral downstream pressure gauge and pressure setting adjustment knob.
