Deltrol Air Bleed Valves

The Pneu-Trol Air Bleed Valve is used to remove trapped air from a hydraulic system, allowing system pump to prime itself. The valve will pass air or a small amount of oil with pump pressure below 50 PSI. Trapped air in the system is bled off back to the reservoir until a solid stream of hydraulic fluid at +50 PSI closes the valve. This is automatic during every system start-up. The valve should be installed at the high point of the hydraulic system using a tee connection.
