Throttle valves can be used where volume flows have to be infinitely controlled in both directions without taking pressure fluctuations into account. The line mounted design with BSP ports is ideal for installing in-line for power packs or hydraulics circuits.

A fine tread on the adjustable throttle reveals an annular gap. The adjusted throttle cross-section produces a pressure drop which determines the volume flow. The volume flow is zero when the throttle is screwed in (the metal sealing edge seals completely). The valve flow is bidirectional.

Hardened and ground spindles with machined and hardened seats give excellent flow characteristics with zero leakage. Installation is quick and easy due to the standard port sizes.
