HAWE QR30 Throttle Valve

HAWE QR30 belongs to the narrow‑groove one‑way throttle valve, integrating flow regulation and one‑way conduction. It enables controllable flow adjustment in one direction while allowing free medium flow in the reverse direction, meeting the speed control requirements of various actuators.

HAWE QR series hydraulic valves adopt proven narrow‑groove throttling structure. Compared with conventional needle‑type throttles, they feature stronger resistance to minor oil contamination, stable performance under low‑flow conditions and favorable linearity of throttling‑area variation, facilitating precise on‑site fine‑tuning of circuit flow. Opening adjustment can be implemented with an Allen wrench. Equipped with a locking mechanism, it retains the set position after adjustment to prevent opening drift during operation.

Supporting multiple mounting options, HAWE QR30 throttle valve can be embedded into manifold blocks or connected to pipelines via pipe fittings. Its compact structure eases equipment layout. Internally functional components are precision‑machined after hardening, delivering high overall reliability and easy maintenance. Widely used in general hydraulic circuits of construction machinery and special‑purpose equipment, it controls cylinder moving speed, cushions reversing shocks and suppresses system oscillation, suitable for speed regulation of both single‑acting and double‑acting actuators.
