Solenoid Valve Coil With Connectors
Reliable Electromagnetic Control for Hydraulic Systems A solenoid valve coil is the electrical heart of any hydraulic or pneumatic control system. When the coil fails, the valve cannot open or close – stopping fluid flow and halting equipment operation. The solenoid valve coil with connectors from Flying Bull provides a direct replacement solution for construction machinery, industrial equipment, and agricultural machines that use Deutsch-plug connections. This hydraulic solenoid valve coil converts electrical energy into magnetic force. When energized (AC220V in this configuration), the coil generates a magnetic field that pulls the moving iron core. That core opens the valve port, allowing oil or air to flow. When power is removed, a spring returns the core to its original position, closing the valve. This on-off action controls cylinders, motors, or other actuators in your machine. Flying Bull’s solenoid coil is constructed entirely of copper windings for efficient heat dissipation and consistent magnetic field strength. The body dimensions are φ20mm (diameter) by 52mm (height), making it suitable for compact valve assemblies. The key feature is the Deutsch plug connector – a rugged, weather-sealed interface commonly used on heavy equipment. Unlike bare-wire coils, the Deutsch connector provides reliable electrical contact even in dusty, wet, or vibration-heavy environments. Key specifications of this coil with connectors: Dimensions: φ20mm × H52mm. Operating voltage: AC220V. Material: all-copper windings. Connection type: Deutsch plug (2-pin, standard). Media compatibility: oil (hydraulic systems). 100% brand new with 1‑year warranty. Delivery: 5–7 working days from Zhejiang, China. For equipment maintenance teams, diagnosing a failed coil is straightforward. Use a multimeter to check resistance. A reading approaching zero ohms indicates a short circuit. An infinite reading means an open circuit (broken wire). Even if resistance appears normal, perform a magnetic test: place a small screwdriver near the metal rod inside the coil while energizing it. If the screwdriver is attracted, the coil works. No magnetic pull means the coil is faulty and needs replacement. Choose the solenoid valve coil with connectors from Flying Bull – a direct-fit, high-quality electromagnetic coil for construction machinery, loaders, excavators, and agricultural equipment.

Handling Short Circuits in Electromagnetic Coils of Solenoid Valves
A solenoid valve comprises a solenoid coil and a magnetic core, integrated within a valve body that features one or multiple holes. The activation of the coil, either by powering on or off, manipulates the magnetic core to allow or restrict fluid flow through the valve body, thereby altering the fluid's direction. The electromagnetic assembly of the valve consists of a fixed iron core, a moving iron core, the coil, and additional components. Meanwhile, the valve body assembly encompasses the spool, spool sleeve, spring base, and other parts. The solenoid is mounted directly onto the valve body, encapsulated within a sealed tube, creating a streamlined and compact design. Commonly manufactured solenoid valves include two-way three-port, two-way four-port, and two-way five-port variations, where "two-way" refers to the valve's powered and unpowered states, corresponding to the controlled valve's open and closed positions.
Addressing Short Circuits in Electromagnetic Coils
Detection Procedure:
● Resistance Measurement: Utilize a multimeter to check the continuity of the coil. If the measured resistance approaches zero, it signifies a short circuit. Conversely, an infinite resistance reading indicates a break in the coil. Note that a normal resistance value does not guarantee the coil's functionality; hence, proceed with further testing.
● Magnetic Test: Place a small screwdriver near the metal rod within the hydraulic solenoid coil. Subsequently, energize the solenoid valve. If the screwdriver is attracted by a magnetic force, it confirms that the solenoid coil is functional. A lack of magnetic attraction indicates a faulty coil.
Company Introduction
Frequently Asked Questions (FAQ)
1. What are the physical dimensions of this solenoid valve coil?
The coil has a diameter of 20mm and a height of 52mm (φ20mm × H52mm). These standard dimensions fit many common solenoid valve bodies used in construction and agricultural machinery.
2. What voltage and connection type does this coil use?
This coil operates on AC220V. It features a Deutsch plug connector (2-pin, weather-sealed), which provides reliable electrical contact in dusty, wet, or high-vibration environments commonly found on heavy equipment.
3. What materials is this coil made from?
The coil uses all-copper windings (enameled copper wire) for efficient heat dissipation and consistent magnetic field generation. The housing and connector are industrial-grade materials rated for oil media exposure.
4. How do I test if my existing solenoid coil is faulty?
Two quick tests:
Resistance test: Use a multimeter. Zero ohms = short circuit. Infinite ohms = open circuit (broken wire). A normal resistance value does not guarantee function – continue to the second test.
Magnetic test: Place a small screwdriver near the metal rod inside the coil while energizing it. If the screwdriver is attracted, the coil works. No attraction means a faulty coil.
5. What equipment is this solenoid valve coil compatible with?
This coil is designed for hydraulic systems using oil as the medium. It fits solenoid valve bodies that accept a φ20mm × 52mm coil with Deutsch plug connection. Common applications include construction machinery (excavators, loaders), agricultural equipment (tractors, harvesters), and industrial hydraulic systems.
6. What warranty and delivery terms are offered?
The coil is 100% brand new and comes with a 1‑year warranty against manufacturing defects. Delivery takes 5–7 working days from Zhejiang, China. Bulk orders and custom packaging options are available upon request.
