Electric Control Valve Manufacturer & Supplier in India
Speciality Valve is a specialized Electric Control Valve Manufacturer and Supplier in India, offering precision-engineered solutions for automated flow regulation. Our electric control valves are designed for accuracy, durability, and easy integration into modern process systems across industries.
Function & Working
Electric control valves regulate flow, pressure, or temperature by adjusting valve position through an electric actuator. The actuator receives a control signal (4–20 mA, 0–10 V, or digital protocols) and positions the valve with high accuracy. This enables precise process control without manual intervention, making them essential for safe, efficient, and automated operations.
Advantages of Electric Control Valves
High-precision flow and pressure regulation
Seamless integration with PLC, DCS, and automation systems
Compact and noise-free operation
Low maintenance with long service life
Flexible actuation: modulating, on-off, or fail-safe options
