Pressure regulator FRU Circulation regulator DN 40  DN 100

Technical description

The DUNGS pressure regulator, type FRU, is a circulation regulator with ad-justable setpoint spring. The pressure regulator complies with EN 88-1. 

• Input pressures up to 150 mbar (15 kPa)
• High flow rate
• Sturdy, precise and sensitive regulation of regulator input pressure (response pressure)
• Inlet pressure compensation diaphragms
• Safety diaphragms
• External pulse as standard
• Rp 1/2 - Rp 2 threaded connection
• DN 40 - DN 100 flange connection

Application

The DUNGS pressure regulator, type FRU, limits the output pressure of a booster to the set value (response pres-sure) when consumption fluctuates. It does not contain any non-ferrous met-als and is suitable for gases up to max. 0.1 vol.% H2S, dry. Suitable for gases of families 1, 2, 3 and other neutral gaseous media.
