Brass Solenoid Valve Diaphragm Type 2/2 Way for Air / Water / Gas for Low Pressure 0-5 Kg/cm2 1/2″ to 2″

For industrial operations that demand consistent, automated flow control at low-to-medium pressures, the Brass 2/2 Way Solenoid Valve stands as a proven and reliable solution.

Engineered as a diaphragm type valve, this 2 way solenoid valve operates on a simple yet highly effective normally-closed (NC) or normally-open (NO) switching principle. The high-grade brass body ensures resistance to corrosion, mechanical stress, and long-term wear — making it suitable for demanding environments across multiple industries. With a pressure range of 0 to 5 Kg/cm² and sizes spanning 1/2″ to 2″, this valve adapts seamlessly to a wide range of pipeline and process configurations.

If you’re looking to buy brass solenoid valve 2/2 way for OEM integration, plant automation, or fluid distribution systems — this valve delivers performance and value in equal measure.

Working Principle:

The brass solenoid valve 2/2 way operates through electromagnetic actuation paired with a flexible diaphragm assembly. When electrical power is supplied to the coil, it generates a magnetic force that lifts the internal plunger. This movement allows the diaphragm to lift off the valve seat, opening the flow path between the inlet and outlet ports.

When the coil is de-energized, a return spring pushes the plunger back, pressing the diaphragm firmly onto the seat and creating a complete shut-off. This pilot-assisted diaphragm action requires minimal power consumption while delivering a tight, leak-free seal. The design keeps the media fully separated from the solenoid assembly — extending operational life and reducing maintenance frequency significantly.

Advantages:

• Competitive Brass Diaphragm Solenoid Valve Price — High-quality engineering at a cost-effective price point for bulk and project procurement
• Low Maintenance Requirements — Diaphragm isolation minimizes internal wear and reduces service intervals
• Fail-Safe Shut-Off — NC configuration closes automatically during power failure, enhancing system safety
• Versatile Media Handling — One standardized valve design covers air, water, and gas applications
• Fast Switching Response — Suitable for high-cycle automation requiring rapid open/close actuation
• Durable Under Continuous Duty — Brass construction and quality diaphragm materials support extended operational life
• Flexible Electrical Compatibility — Multiple coil voltage options reduce the need for additional transformers or converters

Installation Guidelines:

1. Check Flow Direction — Install in line with the directional arrow cast on the valve body to ensure correct media flow
2. Seal Threaded Connections — Apply PTFE tape or approved thread sealant on BSP/NPT joints to prevent leakage
3. Match Coil Voltage — Confirm your supply voltage matches the coil rating before making electrical connections
4. Preferred Mounting Orientation — Coil-up vertical mounting is recommended for optimal performance and heat dissipation
5. Install an Upstream Strainer — Use an 80–100 mesh inline strainer to protect the diaphragm from particulate contamination
6. Respect Pressure Limits — Ensure operating pressure does not exceed 5 Kg/cm² at any point in the system
7. Use Rated Cable Glands — For outdoor or wet environments, use IP65-rated glands and weatherproof wiring
8. Commission with a Test Cycle — Before full start-up, run a manual test cycle to verify open/close operation and check for leaks
