Cartridge Valves - Flow Control Valves - Needle

GSU1

Description

The “B-A” flow is restricted by a calibrated orifice while flow “A-B” is always allowed through the incorporated check valve. Pressure compensation is not provided and flow depends from pressure drop and viscosity.

The GSU1 cartridge is available in different orifice sizes.
