As a European Solenoid Valve & Sensor manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Zhejiang Gongzheng Machinery Co., Ltd. is a professional Wholesale Solenoid Valve Manufacturers and supplier of European solenoid valves and pneumatic sensors for commercial vehicle air brake and control systems. Our product range covers 3/2-way solenoid valves, pilot-operated control valves, ABS modulator valves, EBS axle modulators, exhaust brake solenoids, gearbox solenoid sets, and height/pressure sensors designed for European truck and trailer platforms including Mercedes-Benz, Volvo, Scania, MAN, DAF, Iveco, and Renault.
We manufacture these components in our 30,000 m² factory with automated production lines and in-house testing. Over 70% of the parts are produced internally, giving us direct control over material quality, sealing integrity, and coil performance. Our quality management system is IATF 16949 certified, and our ABS/EBS components comply with ECE R13 standards. Whether you need a direct replacement for aftermarket distribution or a customized solenoid valve for an OEM project, we engineer the solution around your operating voltage, port configuration, and response time requirements.
We supply the following product types within this category. Each type is designed for a specific pneumatic or electronic control function in European commercial vehicles.
| Product Type | Typical Application | Key Specifications |
|---|---|---|
| 3/2-Way Solenoid Valve | Air suspension, door control, auxiliary pneumatics | 12V/24V, normally closed or normally open, IP65 |
| Pilot-Operated Solenoid Control Valve | Main air tank pressurization, clutch assist | High flow, integrated pilot stage, VOSS or flange ports |
| ABS Solenoid Modulator Valve | Anti-lock braking modulation per wheel end | Fast response ≤15 ms, dual-coil safety design |
| EBS Axle Modulator | Electronic braking pressure control on drive/trailer axles | Integrated pressure sensor, CAN communication |
| Exhaust Brake Solenoid Valve | Engine exhaust brake actuation (MAN, Scania, DAF) | High-temperature coil, VOSS interfaces, 24V |
| Gearbox Solenoid Valve Set | Range and splitter control for Scania/Volvo gearboxes | Multi-valve housing, integrated cover, 12V/24V |
| Pneumatic Pressure Sensor | Air tank pressure monitoring, EBS feedback | 0–12 bar, analog or digital output, M12 connector |
| Height Sensor (ECAS/ELC) | Suspension ride height control for Mercedes, MAN, Iveco | Angular displacement, 24V supply, IP67 |
| Dual-Channel Solenoid Valve | Trailer control, multi-circuit safety functions | Redundant coil, manual override option |
Our European solenoid valves and sensors are designed as direct-fit replacements for the original pneumatic and electronic systems used by major European OEMs. We cover the following platforms:
Each component is tested for pneumatic leakage, coil resistance, response time, and environmental endurance before shipment. We maintain a standing inventory of over 200,000 units, enabling fast dispatch for both sample orders and volume replenishment.
When configuring a solenoid valve or sensor for your application, we evaluate the following parameters:
We also offer customization of coil voltage, connector orientation, and mounting bracket geometry for OEM or aftermarket programs. Our R&D team can work from your sample or drawing to develop a matched solution within 4–6 weeks.
Every solenoid valve and sensor we produce undergoes functional testing on dedicated test benches. Our quality process includes:
We hold IATF 16949 certification, and our ABS/EBS components are designed to meet ECE R13 requirements. Test reports are available upon request for each production batch.
To prepare a precise quotation and technical proposal, we need the following project information:
| Data Point | Why We Need It |
|---|---|
| Vehicle make, model, year | Identifies original part number and port configuration |
| Original part number or sample | Ensures exact form, fit, and function match |
| Operating voltage (12V/24V) | Determines coil winding and connector pinout |
| Application (brake, suspension, gearbox, exhaust) | Defines flow, pressure, and temperature requirements |
| Quantity and delivery schedule | Affects production planning and packaging |
| Target market or OEM approval needed | Determines certification and documentation scope |
Submit these details through our inquiry form, and our engineering team will respond with a product datasheet, dimensional drawing, and commercial offer within 48 hours.
Our solenoid valves and sensors are designed for direct bolt-on replacement. Each unit includes a mounting instruction sheet with torque values and wiring diagram. For aftermarket distributors, we provide bulk packaging with individual barcode labels. For OEM customers, we support JIT delivery and kanban replenishment.
Maintenance recommendations include periodic coil resistance check and visual inspection of seal integrity. We stock spare coils, connector kits, and seal repair kits for all popular valve types. Our technical support team is available for remote troubleshooting and can provide on-site assistance for large-scale integration projects.
Our portfolio also includes Products, European Commercial Vehicles for applications with different operating ranges, interfaces or integration requirements.
