RAF 80Q
The RAF 80Q are piloted hydraulic valves 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.
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.
Typical Applications
Use RAF 80Q for general water supply systems with medium pressure rating. The elaborated two-way pilot with Raphael's patented diaghragm enables smooth and precise pressure control.
