2/2 Solenoid Directional Valve Poppet Type, Pilot Operated Normally Open UNF Cartridge – 350 bar up to 150 l/min WS16Y-01 up to 350 bar The directional valve is a pilot operated valve in poppet style. When de-energized, there is free flow through the valve from port 2 to 1. Flow is not possible in the reverse direction. When the solenoid coil is energized, the valve is closed from port 2 to port 1. In the reverse direction the valve will allow flow from port 1 to 2 when the hydraulic force on the piston overcomes the solenoid force (approx. 9 to 20 bar). Please mind: In pilot operated solenoid valves, shift performance and response times depend i.a. very much on pressure drop and volume flow during actuation. FEATURES z Excellent switching performance by high power HYDAC solenoid z Wide variety of connectors available z Coil seals protect the solenoid system z Exposed surfaces zinc-nickel plated for increased corrosion protection (1.000 h Salt spray test) FUNCTION SPECIFICATIONS* Operating pressure: max. 350 bar Flow rate max. 150 l/min up to 280 bar max. 100 l/min, from 280 to 350 bar Leakage: Leakage-free max. 5 drops (0.25 cm³/min) at 350 bar Media operating temperature range: min. -20 °C to max. +100 °C Ambient temperature range: min. -20 °C to max. + 60 °C Operating fluid: Hydraulic oil to DIN 51524 Part 1, 2 and 3 Viscosity range: min. 7.4 mm²/s to 420 mm²/s Filtration: Class 21/19/16 according to ISO 4406 or cleaner MTTFd: 150 - 1200 years, according to DIN EN ISO 13849-1 Installation: No orientation restrictions Materials: Valve body: free-cutting steel Poppet: hardened and ground steel Seals: NBR (standard) FKM (optional, media temperature range -20 °C to +120 °C) Back-up rings: PTFE Coil: steel / polyamide Cavity: FC16-2 Weight: Valve complete: 0.65 kg Coil only: 0.19 kg Electrical data Current draw at 20 °C: 1.5 A at 12 V DC 0.8 A at 24 V DC Coil duty rating: Continuous up to max. 115 % of the nominal voltage at 60 °C ambient temperature Response time: (at pmax, Qmax, ν = 34 mm²/s) energized: approx. 150 ms de-energized: approx. 35 ms substantially extended response times possible at other operating conditions Coil type: Coil…-40-1836 * see "Conditions and instructions for valves" in brochure 53.000 EN 5.940.5/11.18 2 MODEL CODE WS16Y – 01 M – C – N – 24 DG Basic model Directional poppet valve, UNF Type 01 = standard Manual override No details = without manual override M = manual override Body and ports* C = cartridge only Seals N = NBR (standard) V = FKM Coil voltage DC voltages 12 = 12 V DC 24 = 24 V DC AC voltages (bridge rectifier built into the coil) 115 = 115 V AC 230 = 230 V AC Other voltages on request Coil connectors (type 40-1836) DC: DG = DIN connector type A to EN 175301-803 DK = KOSTAL threaded connection M27x1 DL = 2 flying leads, 457 mm long, 0.75 mm² DN = Deutsch connector, 2-pole, axial DT = AMP Junior Timer, 2-pole, radial AC: AG = DIN connector type A to EN 175301-803 Other connectors on request TYPICAL PERFORMANCE DIMENSIONS Pressure drop Flow rate millimeter (inch) subject to technical modifications CAVITY FC16-2 Form tools Tool Part No. Countersink 176218 Reamer 176219 Measured at ν = 34 mm²/s, Toil = 46 °C 2 → 1 de-energized Standard models Model code Part No. WS16Y-01-C-N-24DG 3049587 WS16Y-01-C-N-230AG 3049612 *Standard in-line bodies Code Part No. Material Ports Pressure FH162-SB8 3032496 Steel, zinc-plated G1" 350 bar FH162-AB8 3037193 Aluminium, anodized G1" 210 bar Other line bodies on request Seal kits Code Material Part No. FS UNF 16/N NBR 3651395 FS UNF 16/V FKM 3651396 hex. 1½" Torque * depending on operating pressure Manual override with HNBR-rubber cap After loosening knurled nut, coil can be rotated through 360° and removed.
