The RAF 80Q Quick pressure relief valve is line pressure hydraulically actuated by 2-W quick pressure relief pilot.
The 2-W relief pilot has an upstream sensitive spring-loaded membrane, that can be preset to maintain a desirable upstream pressure.
The RAF 80Q is quickly fully open when upstream pressure exceed the 2-W pilot set pressure. The 2-W pilot configuration together with Raphael’s patented diaphragm enable quick and high flow relief valve opening.
Maximal Nominal Pressure: 16 bar
Setting Range: 0.6 to 6 bar
