Daniel Measurement and Control Inc. Aircraft Refueling Control Valves Series 600

Daniel offers a complete line of valves specifically designed for safe and economical control when fueling all jet aircraft, including supersonic transports. These 600 Series valves are hydraulically operated and suitable for fueling trucks, hydrants and service carts. They control at maximum peak surge with slower closure and lower maximum pressure on its inlet side than any other types of valves. These 600 Series Control Valves are fast, rugged and economical, and accurately control flow rates up to 1,200 gallons per minute. They are used in conjunction with pilot controls and venturies to accurately control flow and maintain pressure throughout the loading process. Model 601 bottom loading valve This Model contains the necessary tubing and sensitivity adjustment needle valve to function as an on-off or regulating valve when controlled by the appropriate pilot valve. The tank truck bottom loading Model 601 is regulated by a Model 410 float pilot mounted in the tank and set to automatically close at a predetermined fuel level. Model 610 closed valve Model 611 open electrical fuel shut-off valve These solenoid operated valves are designed for remote shut-off of fuel on refueler trucks or loading racks. They are available with any standard AC or DC coil. Model 620 closed valve Model 621 open hydraulic or pneumatic fuel shut-off valve These hydraulically or pneumatically pilot operated control valves are designed for remote shut-off of fuel. They are ideally suited for deadman and water slug control. A minimum pressure of 15 psi (103 kPa) is required to operate the pilot. Model 650 pressure reducing control valves These valves are installed in the main line and regulate maximum downstream pressure within ±2psi (13.8 kPa) regardless of variations in flow rate or upstream pressure.
