Type HRAB & HRAR Regulating Valves

GEA’s regulating valves type HRAR and HRAB are regulating and shut-off devices activated by a hand wheel.

At maximum stroke the cone releases the nozzle for regulating. The diameter of the nozzle is equivalent to the valve diameter. The valves are fitted with a back seal (flat sealing ring R). When the valve is fully open, the sealing elements (O-rings, A, B, PTFE ring) can be replaced at the stem by unscrewing the bushing.
