3Way Pressure Reducing & Sustaining Control Valve: RAF 683B
I.T.G. Innovative Technologies Group Ltd is the exclusive distributor of Raphael Valves Industries Ltd products on the territory of the Republic of Azerbaijan and Georgia.
The RAF 683B pressure reducing & sustaining valve is a line pressure hydraulically actuated.
The RAF 683B maintains a minimum upstream pressure, as set on the 3-W pressure sustaining pilot and a maximum downstream as set on the 3-W pressure reducing pilot, regardless of flow changes.
The 3-way pilot configuration together with Raphael’s patented diaphragm enables smooth and precise pressure control.
Typical Applications:
* for water supply systems with medium pressure rating.
* to define two pressure zones along a supply line
* for irrigation water distribution and field control
