ELECTRIC, PILOT OR MANUAL DOUBLE SELECTOR VALVE “DS” O-RING PORTS to eliminate leakage. PRECISION GROUND heat treated spool assures long life. IP69 COIL RATING provides protection against dust and long periods of immersion. SELECTOR SPOOL allows flow to two separate hydraulic circuits. SERIES/PARALLEL SPOOL allows for selection of either series or parallel motor operation. DIAMOND HONED spool bore provides consistent spool fit with low leakage. OIL GROOVES on spool (electric valve only) provide smooth spool motion. OPTIONAL DRAIN PORT for increased pressure rating. Coils: - 12 VDC, 3.5 ohms, 40 watts, and 3.5 amps Ductile cast iron body - 24 VDC, 14 ohms, 40 watts, and 1.75 amps Heat treated steel spool - 120 VAC, 300 ohms, 40 watts, and 0.40 amps Buna N O-rings (standard) Port Sizes: - #8 SAE (3/4-16) all ports - #10 SAE (7/8-14) all ports - #12 SAE (1-1/16-12) all ports - #4 SAE (7/16-20) drain port Weight: 10.0 lbs (4.55 kg). 10 Micron Filtration Recommended. Flow and pressure ratings for Pilot, Lever and Knob actuated valves - #8 SAE – 10 gpm (38 lpm) and 4500 psi (310 bar) - #10 SAE – 18 gpm (68 lpm) and 4500 psi (310 bar) - #12 SAE – 30 gpm (114 lpm) and 4500 psi (310 bar) Pressure and flow specifications for electric actuated found on next page

DS – GENERAL INFORMATION: The Brand Double Selector DS is a 6-way two position double selector valve. We offer this valve with four different operators: electric, pilot, manual lever and manual knob. This valve is typically used to divert flow between two separate circuits. The standard selector spool (open cross-over) allows operation of two double action cylinders or two reversible motors with one 4-way directional control valve. It also allows operation of four single action cylinders with one 4-way directional control valve. When the coil is de-energized top ports C and D are connected...

DS – COMMON DOUBLE SELECTOR APPLICATIONS: Selector spool – used to rotate two uni-directional motors individually Series/Parallel spool – used to rotate two bi-directional motors in series or parallel with one directional control DS – FLOW AND PRESSURE INFO: Series/Parallel spool – used to rotate two bi-directional motors in series or parallel with one bi-directional pump Pressure vs. Flow for Manual/Pilot DS Pressure vs. Flow for Electric DS This line represents the total pressure drop across valve. Total pressure drop equals (Pd-Pf) + (Pb-Pc) or (Pd-Pe) + (Pa-Pc) This line represents the...
