Description
RAF 60 & RAF 63 are piloted hydraulic valves activated by line pressure. The pilot valve has a spring-loaded membrane which is sensitive to downstream pressure.
The pilot's spring is preset to a desirable reducing pressure. The pilot valve maintains a constant downstream pressure by gradually opening & closing of the RAF,
at any flow rate

Applications
Use RAF 60 for general water supply systems with medium pressure rating. 2-way pilot configuration together with Raphael's patented diaphragm, enables smooth & precise pressure control. The plastic Pilot model, RAF 63, is best for irrigation & low pressure applications. Use for domestic, water treatment circulation & filtration networks. The plastic materials & simple design provide high corrosion resistance & cost- effective prices.

RAF 60 - Two-way pilot

RAF 63 - Three-way pilot
