The Series SAE Buttery Valve is an ideal low cost hydraulic reservoir shut off

valve. These valves are designed to meet the demanding needs of the uid power industry. Unique features include an O-ring ange face seal complying with S.A.E. J518 dimensional requirements. This design provides for bubble tight reservoir shut off up to 25 psi (1.72 bar) and a max temperature of 180°F (82.2°C). The compact envelope dimension reduces space requirements. Unit allows for adjustment by incorporating an open/close detent position lock which can be innitely positioned to achieve a desired ow rate. The unique design resists the vibrations associated with hydraulic pumps and pumping systems. Optional uoroelastomer seals and locking handle are available.

FEATURES/BENEFITS

• Flange face complies with S.A.E. J518 dimensional requirements

• Bubble tight shut-off

• Locking handles are available
