The RAF 7R flow rate control valve is line pressure hydraulically actuated, 3-W plastic pilot. Normally the valve is partly open to allow constante flow rate. The head loss across the orifice is proportional to the flow rate.
The RAF 7R maintains a maximum preset flow rate, as set on the 3-W flow rate pilot, and calibrated orifice regardless of pressure changes.
The 3-W pilot configuration together with Raphael’s patented diaphragm enables smooth and precise flow rate control.
Maximal Nominal Pressure: 10 bar
