2/2 Way Low-Pressure Diaphragm Solenoid Valves | Concorde Valves & Automations

For precise, reliable fluid control in low-pressure systems (typically 0–5 bar; up to 6 bar on request), a 2/2 way low-pressure diaphragm solenoid valve is the industry workhorse. Concorde Valves & Automations is one of India’s leading manufacturers and suppliers of these specialized valves. Below, we explain how diaphragm solenoid valves work, why they excel in low-pressure applications, and the advantages they offer across industries.

What is a Diaphragm Type Solenoid Valve?

A diaphragm type solenoid valve is an electromechanical valve that uses a flexible diaphragm to start or stop the flow of liquids or gases. When the coil is energized, the diaphragm lifts to open the passage; when de-energized, it seals the port. This design is especially effective for low-pressure water and air services, making it a smart choice for HVAC, process utilities, and general automation.

Key Features of Solenoid Diaphragm Valves

  • 2/2 Way Functionality: Two ports (inlet and outlet) for straightforward on/off control. Energize to open; de-energize to close for dependable shutoff.
  • Optimized for Low Pressure: Engineered for pressures from 0 to 5 bar (up to 6 bar on request), ideal for water, air, and inert media.
  • Built for Longevity: Robust materials and quality construction deliver consistent performance and reduced maintenance.
