Sun Hydraulics GBY 1GF2-AC Hydraulic Control Valve

Sun Hydraulics GBY 1GF2-AC is a GBY family ISO-03 sandwich-body hydraulic valve that provides flow control for two work ports (A and B) in a compact, modular manifold assembly. The GBY configuration supports meter-in and meter-out operation for precise flow control, with Sun's catalogs illustrating related models such as GBY and GBY/S to indicate different configurations. Standard material options include 6061-T651 aluminum with Buna-N seals or ductile iron with Viton seals, and a seal plate is included; the stack height is 1.75 in and the cavity is T-13A. The interface is ISO-03, and Sun notes that maximum system pressure is dependent on manifold material, with aluminum manifolds typically rated up to 3000 psi (210 bar) regardless of port sizing.
