Diaphragm Operated Solenoid Valve.

Diaphragm Operated Solenoid Valves are among the most widely used flow control devices in industrial and commercial automation systems. These valves combine the precision of solenoid actuation with the reliability of diaphragm-based sealing, making them ideal for controlling the flow of air, water, oil, gas, and other compatible fluids. At Concorde Valves & Automations, we design and manufacture high-performance Diaphragm Operated Solenoid Valves engineered for efficiency, durability, and dependable operation across a wide range of industries.

What Is a Diaphragm Operated Solenoid Valve?

A Diaphragm Operated Solenoid Valve works using an electrically activated solenoid to control the movement of a flexible diaphragm. When the solenoid coil is energized, it lifts a plunger or pilot port, allowing fluid pressure to act on the diaphragm. This causes the diaphragm to move, opening or closing the main valve passage.

These valves are particularly well-suited for applications involving low-pressure drops and large flow capacities, as the diaphragm provides excellent sealing even with minimal actuation force. They are available in direct-acting, pilot-operated, and semi-direct-acting configurations to meet different system requirements.

Design and Construction

At Concorde Valves & Automations, our Diaphragm Operated Solenoid Valves are built from high-quality materials to ensure superior performance and long service life. The valve body is typically made from brass, stainless steel, or engineered plastic, depending on the medium and working environment.

The diaphragm is constructed from high-grade elastomers such as Nitrile (NBR), EPDM, or Viton, which offer excellent resistance to temperature variations, pressure fluctuations, and chemical corrosion. The solenoid coil is available in various voltage options (AC or DC) and is designed for low power consumption and high efficiency.

Each valve undergoes stringent quality checks to ensure precise operation, leak-proof performance, and consistent flow control.
