Solenoid Valve Manufacturers

European Solenoid Valve & Sensor Manufacturer – Zhejiang Gongzheng Machinery

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.

Our European Solenoid Valve & Sensor Range

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.

Application Fit and Vehicle Compatibility

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:

• Mercedes-Benz: Actros, Arocs, Antos – ABS modulator, ECAS height sensor, suspension solenoid
• Volvo: FH, FM, FMX – EBS axle modulator, exhaust brake valve, gearbox solenoid
• Scania: G, R, S series – dual-channel solenoid, PTO valve, gearbox high/low valve set
• MAN: TGS, TGX – exhaust brake solenoid, height sensor, pressure sensor
• DAF: XF, CF – solenoid valve set, pilot-operated control valve
• Iveco/Renault: Stralis, Midlum, Kerax – height sensor, ELC valve block

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.

Critical Specifications and Configuration Options

When configuring a solenoid valve or sensor for your application, we evaluate the following parameters:

• Operating voltage: 12V or 24V DC, with optional suppression diode for transient protection
• Port configuration: VOSS, flange, push-in, or threaded – we match the original interface
• Valve function: 3/2, 2/2, 5/2, normally closed, normally open, proportional
• Flow capacity: Cv from 0.3 to 2.5 depending on valve size and application
• Pressure range: 0–12 bar for pneumatic valves; up to 10 bar for sensors
• Coil type: Standard or high-temperature (up to 120°C ambient) for exhaust brake use
• Connector: Deutsch, AMP, or custom pinout per customer specification
• Seal material: NBR, EPDM, or FKM based on media and temperature

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.

Quality Assurance and Testing

Every solenoid valve and sensor we produce undergoes functional testing on dedicated test benches. Our quality process includes:

• 100% coil resistance and insulation testing
• 100% pneumatic leakage test at 8 bar
• Response time measurement (opening and closing)
• Environmental cycling test (–40°C to +85°C) for sensors
• Salt spray corrosion test per ISO 9227

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.

Information We Use to Configure Your Solution

To prepare a precise quotation and technical proposal, we need the following project information:

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.

Installation, Maintenance, and Support

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.
