EP10W2A06N05 | Winner Solenoid Cartridge Valve 350bar 70L/min

Product Overview

The EP10W2A06N05 and EP16W2A05N05 are core models in the WINNER EP series of pilot-operated poppet-type 2/2 solenoid cartridge valves. Founded in 1993, Winner Hydraulics Corporation has become an internationally recognized manufacturer of hydraulic screw-in cartridge valves.

The EP series features pilot-operated poppet-type construction for direct manifold installation, delivering extremely low internal leakage (≤3 drops/min). With a maximum operating pressure of 350 bar (5000 psi) , the series is widely used in construction machinery, mobile vehicles, marine, wind power, offshore engineering, metallurgy, petroleum, machinery manufacturing, and rubber & plastics machinery.

EP10W2A06N05 (10W-2 Cavity, 70 L/min):

The EP10W2A06N05 fits the 10W-2 cavity and is a pilot-operated normally closed poppet-type solenoid valve. When de-energized, it operates like a check valve—allowing flow from port 1 to port 2 while blocking flow from port 2 to port 1; when energized, bidirectional flow is allowed. Rated flow: 70 L/min (18.49 gpm) , maximum operating pressure: 350 bar (5000 psi) .

EP16W2A05N05 (16W-2 Cavity, 150 L/min):

The EP16W2A05N05 fits the 16W-2 cavity and is a pilot-operated normally closed poppet-type solenoid valve. When de-energized, it operates like a check valve—allowing flow from port 1 to port 2 while blocking flow from port 2 to port 1; when energized, bidirectional flow is allowed. Rated flow: 150 L/min (39.63 gpm) , maximum operating pressure: 350 bar (5000 psi) .

As original WINNER screw-in cartridge valves, these products offer complete interchangeability within the same series and cavity, requiring no modifications to manifold designs.

Key Technical Advantages

1. Pilot-Operated Poppet-Type Leakage-Free Design — Extremely Low Internal Leakage

The EP series features pilot-operated poppet-type spool construction, achieving metal-to-metal sealing against the seat in the closed position. Maximum leakage is only 3 drops/min (0.15 cc/min) . Ideal for high-pressure hydraulic systems requiring long-term actuator position holding with minimal leakage.

2. Pilot-Operated Structure — High Flow with Precise Control

Features pilot-operated construction—the main stage is controlled by the pilot stage. Compared to direct-acting designs, pilot-operated structures enable high flow control with smaller solenoid drive force. Rated flow ranges from 70 L/min (EP10W2A06N05) to 150 L/min (EP16W2A05N05) .

3. Wet-Type Solenoid Design for Quiet, Long-Life Operation

Features wet-armature solenoid construction—the movable iron core operates fully submerged in hydraulic oil, providing lubrication to reduce wear and cushioning against switching impact and vibration. Coils are continuous-duty rated and can be replaced without opening the hydraulic system.

4. Heat-Treated and Precision-Ground Poppet for Superior Wear Resistance

Critical control elements are heat-treated and high-precision ground, significantly increasing surface hardness and reducing wear. This ensures long-term sealing performance with extremely low internal leakage.

5. WINNERcoat® Zinc-Nickel Plating for Superior Corrosion Resistance

All exposed surfaces feature WINNERcoat® Zinc-Nickel Plating, with salt spray testing per DIN EN ISO 9227 exceeding 1000 hours . Particularly suitable for offshore engineering, marine, mining, and other humid/corrosive environments.

6. International Standard Compliance with 100% Functional Testing

Winner cartridge valves are pressure-rated per NFPA T2.6.1 standards, with fatigue rating assurance/verification level of “90/90” . All products undergo 100% functional testing before shipment.

7. Coils Must Be Ordered Separately — Flexible Configuration

EP series coils must be ordered separately. Available with EC-04W 20W coils, supporting multiple voltage options for different control system requirements.

Expert Maintenance Tips

1. Installation Guidelines

• EP10W2A06N05 fits 10W-2 cavity. EP16W2A05N05 fits 16W-2 cavity.

• Thoroughly clean the cavity and valve exterior before installation to prevent foreign particles from entering and causing seal damage or spool sticking.

• Recommended installation torque: 10W-2 cavity 44–56 N·m (32–41 lbf·ft) ; 16W-2 cavity 80–100 N·m (59–74 lbf·ft) . Reduce torque for aluminum manifolds.

• No orientation restrictions.

2. Hydraulic Fluid Cleanliness

• Recommended filtration: 25 μm (nominal or better) .

• Fluid temperature range: -40°C to +120°C.

• Use standard mineral-based or synthetic hydraulic fluids.

3. Electrical Connection Specifications

• Both models use 24V DC supply with power consumption of 20 W.

• Minimum voltage required: 90% of nominal.

• Coils are continuous-duty rated.

• Coils must be ordered separately.

• Ensure electrical connector is fully locked to maintain IP65 protection.

4. Seal Material Selection

• WINNER offers multiple seal kit materials for different applications.

• Standard NBR seals for mineral oil systems; FKM seals optional for phosphate ester and other specialty fluids.

5. Periodic Maintenance Inspection

• Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.

• Check electrical connectors for looseness, oxidation, or moisture ingress.

• If response lag or unstable shifting is observed, first check system fluid cleanliness and poppet seal condition.

• The EP series poppet design features extremely low internal leakage—if abnormal leakage increase is observed, inspect the valve seat sealing surface for damage.
