Vehicle-Mounted Fuel Dispenser Solenoid Valve Assembly 12VDV1050-F-10CSCH2312
Technical Specifications & Operational Characteristics
| Key Technical Indicator | Specification / Data | Industrial Application Notes |
|---|---|---|
| Control Type | Dual-Flow Control (Open / High Flow / Low Flow / Closed) | Enables precise fuel delivery control. It automatically switches to a low flow rate (2 ~ 4.5 L/min) as the refueling process nears completion, preventing fuel overflow and ensuring microscopic metering accuracy. |
| Applicable Media | Gasoline, Diesel, Kerosene, etc. | The internal main valve diaphragm is made of imported, high-elasticity, corrosion-resistant specialized rubber. It resists swelling and cracking even when exposed to low-grade or harsh fuels. |
| Explosion-Proof Rating | Ex mb IIC T4 Gb (or equivalent) | Features an encapsulated type of maximum explosion-proof safety class. It fully complies with safety regulations for mobile fuel trucks operating in hazardous environments with static electricity and flammable gases. |
| Ambient Temperature Range | -40 C̊ to +55 C̊ | Meets the outdoor operating requirements of mobile refueling trucks in alpine or low-temperature regions. The valve actuation does not suffer from lagging or delays at low temperatures. |
| Operating Pressure Range | Maximum 0.35 MPa (approx. 3.5 bar) | Perfectly matches the fuel delivery pressure intervals of truck-mounted gear pumps or submersible pumps. |
Notes on On-Site Overhaul and Replacement (BOM Recommendations)
1. Solenoid Coil Section: Refers to the black, explosion-proof, encapsulated coil marked "12V" and "10CSCH2312." If the dispenser shows a count on the display but no fuel flows from the nozzle, or if the fuse blows frequently, the coil is likely burnt out; the dedicated DV1050-12V explosion-proof coil can be purchased and installed separately.
2. Main Valve Body and Main/Pilot Valve Diaphragms: If fuel continues to drip or leak after the nozzle is closed, or if the system fails to switch to low-flow mode, the issue is usually caused by debris obstructing the internal valve seat or by the wear and aging of the rubber diaphragms. In such cases, the diaphragm repair kit or the entire valve body assembly needs to be replaced.
3. Flange Seals: When replacing the assembly, the anti-static, oil-resistant O-rings or gaskets at the connecting flanges on both ends must also be replaced to strictly prevent fuel leakage.
Bill of Materials (BOM) for Solenoid Valve Assembly
| No. | Part Name | Function & Maintenance Recommendation |
|---|---|---|
| 1 | DV1050-12V Dual Explosion-Proof Coil | The core electrical actuator of the valve. If the valve fails to actuate due to coil burnout, short circuit, or loose connector plugs, remove the top nut and replace this coil directly. |
| 2 | Main Valve Rubber Diaphragm | Made of imported specialized fluororubber (FPM/Viton) to ensure low-temperature resistance and anti-swelling properties against fuel. If the fuel dispenser keeps creeping/metering after the nozzle is closed, this diaphragm usually needs replacement. |
| 3 | Auxiliary Valve Diaphragm & Pilot Springs | Precision diaphragm and return springs responsible for low-flow stage switching. Inspect and replace this kit if the system fails to enter the low-flow stage (e.g., shuts down completely or fails to decelerate). |
| 4 | Valve Seat & Metal Valve Body | Generally made of premium brass or aerospace-grade alloy. This part rarely gets damaged unless the fuel contains iron filings or debris that scratch and wear down the valve port. |
| 5 | Flange O-rings & Sealing Gaskets | Fuel-resistant gaskets located at both end-flange connections of the valve body. These must be replaced mandatory during any overhaul or disassembly to prevent external leaks caused by vehicle vibration. |
