MRI51 - Slow start valve
Slow starter for progressive pressurization, prevents pressure shocks (Cmatic MV 50)
This fitting allows for a progressive pressurization of the installation and prevents the actuators from being hit hard in case of sudden pressure feeding of the previously vented circuit. The actuators return to their working position smoothly without being hit.
Pressure feeding speed is determined by the rotation of the spindle: if turned clockwise, a very smooth pressurization will be achieved. The valve opens fully once the pressure reaches approximately 2/3 of the inlet pressure.
