A solenoid controlled valve is one of the most widely used automation valves in modern industrial fluid control systems. It combines electrical control with mechanical valve operation, allowing precise, fast, and reliable control of liquids, gases, steam, air, and other compatible media. In Indian industries where efficiency, safety, and automation are becoming critical, solenoid controlled valves play a central role in improving process accuracy and reducing manual intervention.
A solenoid controlled valve works by using an electromagnetic solenoid coil to actuate the valve mechanism. When electrical power is applied, the solenoid generates a magnetic field that moves a plunger or pilot mechanism, opening or closing the valve. This simple yet robust principle makes solenoid valves ideal for automation applications across water treatment plants, chemical industries, pharmaceuticals, food and beverage units, textile processing, power plants, irrigation systems, and HVAC installations.
Solenoid controlled valves are closely related to automation valves, electrically operated valves, pneumatic solenoid valves, pilot operated solenoid valves, and direct acting solenoid valves. These related product categories are often searched together by Indian buyers looking to automate flow control with reliable and cost-effective solutions. In many industrial setups, solenoid controlled valves are integrated with PLC systems, control panels, timers, pressure switches, and sensors to ensure smooth and safe operation.

What is a Solenoid Controlled Valve
A solenoid controlled valve is an electrically actuated valve that uses a solenoid coil to control the flow of fluid. The valve can be normally closed, normally open, or bistable depending on the application. When power is supplied to the solenoid coil, it energizes and moves the internal plunger, changing the valve position. When power is removed, the valve returns to its default position using spring force or pressure differential.
Solenoid controlled valves are available in different configurations such as two-way, three-way, and four-way designs. Two-way solenoid valves control on-off flow, three-way valves are used for diverting or mixing flow, and four-way valves are commonly used in pneumatic systems to control double-acting actuators.
Depending on pressure and flow requirements, solenoid controlled valves can be direct acting or pilot operated. Direct acting solenoid valves operate without relying on line pressure, making them suitable for low pressure or vacuum applications. Pilot operated solenoid valves use line pressure to assist valve operation, making them ideal for higher flow rates and higher pressure systems commonly used in Indian industrial plants.
Types of Solenoid Controlled Valves Offered
Krishna Industries supplies a wide range of solenoid controlled valves to meet diverse Indian industrial requirements.
Direct Acting Solenoid Controlled Valve These valves are suitable for low flow and low pressure applications. They operate independently of line pressure and are commonly used in laboratory equipment, small machinery, medical devices, and low pressure water or air lines.
Pilot Operated Solenoid Controlled Valve Pilot operated solenoid valves are designed for higher pressure and larger flow applications. They are widely used in water supply lines, industrial pipelines, boilers, cooling systems, and chemical processing plants across India.
Normally Closed Solenoid Controlled Valve In this configuration, the valve remains closed when power is off and opens only when energized. This is the most commonly used type for safety-critical applications where flow must stop during power failure.
Normally Open Solenoid Controlled Valve These valves remain open when power is off and close when energized. They are used in applications where continuous flow is required unless interrupted by control signals.
Material Based Solenoid Controlled Valves Solenoid controlled valves are available in brass, stainless steel, cast iron, and special alloy constructions. Brass solenoid valves are widely used in water, air, and light oil applications. Stainless steel solenoid valves are preferred for corrosive fluids, food processing, pharmaceuticals, and chemical industries.
Working Principle of Solenoid Controlled Valve
The working principle of a solenoid controlled valve is based on electromagnetic attraction. When electric current flows through the solenoid coil, it generates a magnetic field. This magnetic field pulls the plunger into the coil, opening or closing the valve orifice. In pilot operated valves, the solenoid controls a small pilot orifice that uses system pressure to move the main valve diaphragm or piston.
This design ensures fast response time, reliable operation, and minimal power consumption. In Indian industrial environments where voltage fluctuations and continuous operation are common, properly designed solenoid controlled valves ensure stable performance and long service life.
