RAF/RAF-P 93
Pressure Rating PN-10
Nominal Diameter 1" - 6D"
The RAF/RAF-P 93 anti-burst control valve is a line pressure hydraulically actuated, 3-W plastic pilot. Normally the valve is open. Only in case of flow rate higher than a preset maximum, due to a burst or excessive demand downstream the 93 is automatically closed down and can reopen manually.
The 93 closes automatically whenever the upstream pressure drops below a preset point. The 93 features a plastic pilot valve and hydraulic relay to ensure precise and reliable response in general use.
Typical Applications
Use 93:
* with an all-plastic pilot for use in agriculture applications, features a cost effective, simple and reliable command loop
* to eliminate water loos and damage due to piping burst
* the valve is best in networks susceptible to burst due to vandalism or pressure surge
