Hydraulic Needle & Speed Control Valves

HYDAC needle valves are manually actuated flow valves for influencing a flow rate by means of an adjustable cross-section using a throttle spindle. The flow rate is dependent on differential pressure and viscosity.

A pneumatic flow control valve, commonly known as a speed controller, is a hydraulic safety device that protects pneumatic components, such as a cylinder, from damage. A speed controller opens a valve when air flows from the left to the right, establishing a free flow of air inside the valve.
