Description
.RAF 80Q is a piloted hydraulic valve activated by line pressure. The two-way pilot valve has a spring-loaded membrane which is sensitive to upstream pressure. The RAF 80Q is normally closed. As line pressure rises above the preset level, the valve opens quickly to relieve the excessive pressure.


Applications
Use RAF 80Q for general water supply systems with medium pressure rating. The elaborated two-way pilot with Raphael's patented diaphragm enables smooth & precise pressure control. Quick pressure relief valve protects water systems from quickly rising excessive pressure, due to water hammer surge. It is recommended to install RAF 80Q at the system head, right next to the main supply line or booster pump.
