Solenoid Valve Cartridge

Product Specifications

Technical details and manufacturing context for Solenoid Valve Cartridge

Definition

A solenoid valve cartridge is a modular, self-contained valve assembly that houses the solenoid actuator, valve seat, and flow control elements. It is specifically engineered to be inserted into a manifold block, forming part of a larger control valve manifold system used for directing, regulating, or shutting off fluid flow in automated industrial processes. The cartridge design allows for quick replacement without disturbing the manifold piping, reducing downtime in maintenance operations. Typical applications include hydraulic and pneumatic systems in machinery, process control, and automation. The cartridge integrates a solenoid coil, a plunger or armature, a pilot orifice, and a main valve seat, all enclosed in a compact body. The body is commonly made of stainless steel or brass, with seals available in NBR, FKM, or EPDM to suit different media and temperature ranges. The solenoid coil is typically copper wound with a plastic housing. The cartridge operates on a pilot-operated principle: when the coil is energized, the magnetic field moves the armature, opening or closing the pilot orifice, which changes the pressure differential across the main valve diaphragm or piston, causing the main valve to open or close. This design allows for reliable switching of high-flow paths with low electrical power consumption. The cartridge is available in various configurations to meet specific flow, pressure, and response time requirements. For selection, the user must verify the operating pressure range, flow rate, response time, coil resistance, supply voltage, power consumption, operating temperature, IP rating, body and seal materials, leakage rate, and weight against the intended application. All values listed in the directory are reference ranges and must be confirmed with the legal manufacturer or supplier for the specific model. The cartridge should be installed and maintained according to the manufacturer's instructions to ensure proper function and safety.

Working Principle

When an electrical current is applied to the solenoid coil, it generates a magnetic field that moves a plunger or armature. This mechanical movement either opens or closes a small orifice (the pilot orifice), which in turn controls the pressure acting on the main valve diaphragm or piston. The pressure differential causes the main valve to open or close, allowing or blocking the main flow path through the manifold. The pilot-operated design enables the valve to control high flow rates with a relatively small solenoid, as the main valve is actuated by the pressure difference rather than directly by the solenoid force. The response time is typically 10 to 30 milliseconds at rated voltage, depending on the model and operating conditions. The cartridge is designed for integration into a manifold, where multiple cartridges can be combined to create complex control logic. The working principle is consistent across different models, but the specific dimensions and materials may vary. It is essential to verify the electrical and fluid parameters with the manufacturer to ensure compatibility with the intended system.

Frequently Asked Questions

What is the operating pressure range for this solenoid valve cartridge?

The directory lists a reference operating pressure range of 1.0 to 1.6 MPa. However, the actual allowable pressure range depends on the specific model and configuration. You must verify the exact pressure rating with the legal manufacturer or supplier before installation.

What materials are available for the body and seals?

The body can be made of stainless steel (typically 304 per ASTM A276) or brass. Seals are available in NBR, FKM, or EPDM, with FKM as a common option. The choice of materials affects chemical compatibility and temperature limits. Confirm the material options for your specific model with the manufacturer.

How does the pilot-operated principle work?

When the solenoid coil is energized, it moves the armature, which opens or closes a pilot orifice. This changes the pressure differential across the main valve diaphragm or piston, causing the main valve to open or close. This allows the valve to control high flow rates with a relatively small solenoid.

What are the electrical specifications?

The reference supply voltage is 24 V DC, with a range of 9-36 V DC. Coil resistance is 24 Ω ±10% at 20°C, and power consumption is 4-8 W (holding power). These values are typical and must be verified for the specific model with the manufacturer.
