Direct-operated solenoid valve SDBB series

NONClow power consumption

The 360° Ported Single-Coil Solenoid Valve utilizes a unique MultiSeal® design that provides 360° porting flexibility. In exchange, this valve has a slight reduction in flow capacity when compared with our standard piloting solenoid valve. The MultiSeal technology eliminates the use of O-rings, offering significant space and weight savings. The valve’s innovative coil design provides low power consumption and fast response times. - Lohm Rate: 3500 Lohms max - Operating Pressure: 3000 psid - Leakage: 1 cc / minute max - Weight: 0.14 lbs max - Unique MultiSeal® Configuration General Performance - Operating Pressure: 3000 psid - Operating Ambient Temperature: -65°F to 275°F - Operating Fluid Temperature: -65°F to 275°F - Internal Leakage: 1 cc / Minute Max at Rated Pressure - External Leakage: 0 cc - Lohm Rate: 3500 Lohms - Current Drain: 0.28 amps at 28 VDC at 70°F (7.8 Watts) - Max Operating Voltage: 32 VDC - Resistance: 92 - 108 Ohms at 70°F - Pull-In Voltage: 18 VDC Max at 275°F and 3000 psi - Dropout Voltage: 2 VDC Min at 70°F and 3000 psi - Pull-In Response Time (28 VDC at 70°F and Rated Pressure): 0.035 Seconds Max - Dropout Response Time (28 VDC at 70°F and Rated Pressure): 0.035 Seconds Max - Nominal Screen Hole Size: 0.004 inches - Weight: 0.14 lbs Max Materials Wetted Parts - Filter Screen: 304L CRES, ASTM A666, Passivated - MultiSeal: Polyamide-Imide, AMS 3670 - Body and Ball Seat: 15-5 PH CRES, AMS 5659, Passivated - Ball and Pin: 440C CRES, AMS 5630, Passivated - Shaft: 440C CRES, AMS-QQ-S-763, Passivated - Spring: 302 CRES, AMS 5688, Passivated - Plug and Pushrod: 303 CRES, QQ-S-763C, Passivated - Flanges and Plungers: Si Iron BFM, ASTM A867, Nickel Plate / AMS 2404 - Shunt: 22-13-5 CRES, AMS 5764, Nickel Plate / AMS 2404 - Shims and Spacers: 302 CRES, ASTM A666, Passivated - Braze: Silver Alloy, AMS 4774, Nickel Plate / AMS 2404 Non-wetted Parts - Cover: Si Iron BFM, ASTM A867, Nickel Plate / AMS 2404 - Retainer: 2024 T-351 AL, AMS-QQ-A-225 / 6, Anodize / MIL-PRF-8625 Type II - Retaining Ring: 302 CRES, ASTM A313 / A313M, Passivated - Coil: Copper Magnet Wire, NEMA MW1000 / MW16 - Shrink Tube: PVDF and PTFE, AMS-DTL-23053 / 8 & / 12 - Insulation Tape: Polyimide, ASTM D5213 - Solder: Sb05A, J-STD-006 - Potting Compound: Stycast 2762FT, Catalyst 17 - Lead Wire: 22 AWG, SAE AS22759 / 11 Part Numbers & Specifications - SDBB2531002A: 3000 psi, Skydrol, Normally Open, Lead Wire Front - SDBB2531003A: 3000 psi, Skydrol, Normally Closed, Lead Wire Front - SDBB2531012A: 3000 psi, MIL-PRF-5606 or MIL-PRF-83282, Normally Open, Lead Wire Front - SDBB2531013A: 3000 psi, MIL-PRF-5606 or MIL-PRF-83282, Normally Closed, Lead Wire Front Replacement Parts & Accessories - CUTA2500221B: MultiSeal Extraction Tool - SDBB2530108A: Replacement MultiSeal - CUTA2500021A: Test Fixture - Flow Curve, Cross Section View, Dimensional View, and Mounting Details available as images (see images section). - CAD Envelopes available for Normally-Closed and Normally-Open models (download requires gated access). - Handbook: Technical Hydraulic Handbook of Aerospace, Energy, and Motorsport Solutions (see documents section).
