The RAF 70 flow rate control valve is line pressure hydraulically actuated, 2-W pilot. Normally the valve is partly open to allow a constant flow rate. The head loss across the orifice is proportional to the flow rate.
The RAF 70 maintains a constant preset flow rate, as set on the 2-W flow rate pilot, regardless of pressure changes.
The 2-W pilot configuration together with Raphael’s patented diaphragm enable smooth and precise flow rate control.
Maximal Nominal Pressure: 16 bar
Setting Range: 0.6 to 6 bar
