DEVICE DESCRIPTION
2.1 General Description
The Booster Relay BR is a flow amplifier that allows to increase the actuator stroking time by increasing the
fluid mass flow to the actuator or from the actuator. Designed to meet high control applications, the BR
booster contains an integral stabilizing bypass valve controlled by a screwdriver adjustment. The bypass
valve screwdriver creates a pressure drop between the pilot and the actuator connection depending on its
adjustment and the working fluid flow rate.
