Overview Download View Technical Specifications Download View

The throttles described here are designed as slot-type throttles and are therefore impervious to micro-contaminants (no edge filter effect). The check valve function of types CQR and CQV is performed by a shim that guarantees short response times. The double spindle seal enables leakage-free adjustment, even under pressure.

Features and benefits:
■ Leak-free adjustment under pressure
■ Operating pressure up to 700 bar


Intended applications:
■ Speed regulation in hydraulic lifting devices
