Coils for hydraulic solenoid valves

What are coils for hydraulic solenoid valves ? Coils for hydraulic solenoid valves are key components of control systems in power hydraulics. Their main task is to convert electrical energy into magnetic energy, which then enables control of the working fluid flow in the valve. In practice, this means that after applying voltage, the coil produces a magnetic field that attracts the valve core (plunger), causing it to open or close. This makes it possible to precisely and quickly control the movement of actuators, hydraulic motors or other receivers in the system. The coils for hydraulic solenoid valves available in our store are a combination of high quality workmanship, durability and compliance with international standards. We offer both standard and specialized models, adapted to work under conditions of increased load. Our products are used in many industrial sectors, and their reliability is confirmed by customer opinions and numerous quality certificates.

Construction and principle of operation of hydraulic coils

The coil for a solenoid valve is made of a copper wire winding, a ferromagnetic core and a housing that protects the components from mechanical damage and external factors. Depending on the type of solenoid valve and power supply parameters, coils can operate at 12V DC, 24V DC, 24V AC, 110V AC or 230V AC. Hydron offers a wide range of coils compatible with valves from various manufacturers, made of durable materials resistant to high temperatures and vibrations. Many models have protection class IP65, IP67 or higher, which guarantees safe operation even in difficult industrial conditions.

Application of coils in hydraulic systems

Solenoid valve coils are used in every modern hydraulic system where there is a need for precise flow control. They are used, among others, in:

• construction and agricultural machinery,

• presses and injection molding machines,

• production lines and industrial automation,

• mobile and stationary devices.

Thanks to different voltage ranges and mounting types, it is possible to easily match the appropriate coil to a specific valve or application.

How to choose the right coil for a solenoid valve?

When choosing a coil, pay attention to several important parameters: 

• supply voltage (DC/AC) – compliant with the control system,

• diameter and mounting type – adapted to a specific valve,

• power and current consumption,

• tightness class and operating temperature,

• electrical connector type (DIN, AMP, DEUTSCH, etc.).
  A well-chosen coil guarantees the correct operation of the valve and the entire hydraulic system.
