Excavator Solenoid Valve
Versatile Hydraulic Control with the Excavator Solenoid Valve SV08-30 Hydraulic systems in construction machinery need reliable, fast-acting valves to control oil flow. The excavator solenoid valve from Flying Bull (Model SV08-30 / 246284 / DHF08-232) is a direct-acting, 3-way, spool-type directional valve designed for ordinary pressure hydraulic systems. It is widely used not only in excavators but also across steel, metallurgy, petrochemical, aerospace, shipbuilding, coal, cement, electric power, automotive, food, forestry, textile, leather, and paper industries. The SV08-30 solenoid valve is a hydraulic thread directional valve with an electromagnetic drive. It features a hard-treated spool and valve sleeve for long service life even under frequent operation. The valve uses an efficient wet armature structure, meaning the moving parts are bathed in hydraulic oil for lubrication and cooling. Key technical parameters: Maximum working pressure: 50 bar (for pilot/control circuits) – note the valve is rated for 210 bar internal pressure sealing. Internal leakage: less than 80 ml/min at 210 bar. Operating voltage options: 12VDC, 24VDC, 110VAC, 220VAC (minimum operating voltage 85% of rated voltage). Filtration requirement: 20μm or better. Standard cavity: T4-2. Standard valve block models: T4-21 / T4-23 / T4-24 / T4-26. Temperature range: -30°C to +100°C (nitrile rubber seals). Rated flow: 20 L/min. High pressure rating: 210 bar. How the SV08-30 valve works: In its normal (de-energized) state, the valve allows hydraulic oil to flow from port 1 to port 2, but blocks flow from port 2 to port 1 (one-way check). When the solenoid is energized, the spool shifts, allowing oil to flow from port 2 to port 1. This configuration is typical for controlling pilot circuits or transmission functions in hydraulic systems. At 210 bar and oil viscosity of 46 cSt, leakage from port 2 to port 1 is only 0.10 ml/min (about 2 drops per minute). Key features of this excavator solenoid valve: Rated solenoid suitable for continuous operation. Hard-treated spool and sleeve – resistant to wear. Multiple coil voltage and terminal options. Efficient wet armature design. Plug-in voltage coils are interchangeable. All oil ports can be fully pressurized. Emergency manual override option available. Optional IP69K waterproof E-coil for harsh environments. Integrated molded coil design. Full guide spool for stable operation. Compact structure fits tight machine compartments. Operating temperature range: -20°C to +90°C (standard seals), with -20°C to +120°C option. The SV08-30 excavator solenoid valve is 100% brand new, manufactured in Zhejiang, China, and backed by a 1‑year warranty. Delivery takes 5–7 working days. For equipment owners and repair shops, the SV08-30 offers a reliable, versatile solenoid valve for countless hydraulic applications. Choose Flying Bull for quality construction machinery parts.

Company Introduction
Frequently Asked Questions (FAQ)
1. What is the model number and basic specification of this excavator solenoid valve?
The valve is available under model numbers SV08-30, 246284, and DHF08-232. It is a direct-acting, 3-way, spool-type hydraulic thread directional valve. It operates with oil media under ordinary pressure.
2. What is the maximum working pressure and flow rate of the SV08-30?
The valve has a maximum working pressure of 50 bar for pilot/control circuits. However, it is rated to seal internal pressure up to 210 bar. Rated flow is 20 L/min at 210 bar.
3. What voltage options are available for this solenoid valve?
The coil is available in 12VDC, 24VDC, 110VAC, and 220VAC. The minimum operating voltage is 85% of the rated voltage. Plug-in voltage coils are interchangeable.
4. How does the SV08-30 valve work in normal (de-energized) vs. energized state?
Normal (de-energized): Oil can flow from port 1 to port 2, but flow from port 2 to port 1 is blocked (one-way check).
Energized: The spool shifts, allowing oil to flow from port 2 to port 1. This configuration is typical for controlling pilot circuits or transmission shift functions.
5. How much internal leakage does this valve have?
At 210 bar and oil viscosity of 46 cSt, internal leakage from port 2 to port 1 is only 0.10 ml/min – approximately 2 drops per minute. Maximum allowable leakage is less than 80 ml/min at 210 bar.
