A holding brake is an electromechanical device used to hold the valve in position against the pressures of the fluid dynamics or the resiliency of the seat. Typical holding brakes include solenoid, cork, relay, and spring and are ordered as optional (all DC positioners have relay brakes standard.) A stopping brake is an electronic device used to stop the motor shaft instantly to prevent coasting and overshooting. Valvcon incorporates this electronic function in all positioner boards.
