In many industrial systems, automated flow control is critical for safety, accuracy, and efficiency.
A common issue faced by engineers and procurement managers is choosing the correct control valve to avoid failures. such as leakage, slow response, or energy waste. One of the most widely used options is the solenoid valve.
This article explains what a solenoid valve is, how it works, its applications, and key specifications that matter for B2B engineering projects.
A solenoid valve is an electromechanically operated valve that uses an electric current (through a solenoid coil) to control the opening or closing of a valve seat.
It functions as an on/off control device for liquids or gases, enabling automated, remote, or timed operation.
Buyer tip: Always match seal material with process media (e.g., FKM for fuels, EPDM for water).
The principle is straightforward: when the solenoid coil is energized, it creates a magnetic field that pulls the plunger upward, opening the valve and allowing fluid to pass.
When the coil is de-energized, a spring pushes the plunger back to seal the orifice, stopping flow. This rapid switching mechanism allows precise control of flow in automated systems.
Engineer’s tip: For high-pressure systems (>10 bar), pilot-operated designs reduce coil power requirements.
Solenoid valves are used across multiple industries where fast, reliable, and automated shut-off is needed:
Case example: A water treatment plant replaced manual globe valves with automated solenoid valves, reducing operator intervention by 40% and improving dosing accuracy.
Procurement reminder: Always check IP protection (e.g., IP65/IP67) for coils in outdoor or wash-down environments.
Buyer tip: For modulating control, consider globe or pneumatic valves; solenoids are primarily on/off devices.
