U.S. Solid 3/4" Brass Electric Solenoid Valve

1. Product Overview

The U.S. Solid 3/4" Brass Electric Solenoid Valve is a high-quality, normally closed valve designed for various industrial applications. Its robust brass construction and VITON seal ensure durability and compatibility with a range of fluids including non-potable water, air, diesel, gasoline, kerosene oil, and natural gas.

This valve is engineered for rapid response, opening or closing in less than 1 second. It is important to note that this valve is not designed for continuous duty; prolonged use exceeding 8 hours in a single cycle may shorten its lifespan and cause damage.

5. Setup and Installation

1. Preparation: Ensure the power supply is disconnected before beginning installation. Verify that the fluid type is compatible with brass and VITON seals. This valve is not suitable for drinking water applications.
2. Thread Sealing: Apply appropriate thread sealant (e.g., PTFE tape) to the pipe threads before connecting the valve to prevent leaks.


Figure 5.1: Proper application of thread sealant is crucial for leak-free connections.

3. Flow Direction: Observe the flow arrow indicated on the valve body to ensure correct installation direction.

4. Mounting: Mount the valve securely in a position that allows for easy access for wiring and maintenance.
5. Electrical Connection: Connect the valve to a 110V AC power source. Ensure all electrical connections are secure and properly insulated. Refer to Figure 3.1 for wiring reference.

6. Operation

This is a normally closed solenoid valve. When electrical power (110V AC) is supplied to the coil, the valve will energize and open, allowing fluid to flow. When the power is removed, the valve will de-energize and close, stopping the fluid flow.

The valve is designed for quick actuation, opening or closing almost instantaneously. Avoid continuous operation for more than 8 hours in a single cycle to prevent overheating and potential damage to the coil.

7. Maintenance

• Regular Inspection: Periodically inspect the valve for any signs of leaks, corrosion, or damage to the wiring.
• Cleaning: Keep the exterior of the valve clean and free from debris. Do not use harsh chemicals that may damage the brass or rubber components.
• Coil Check: Ensure the coil is not excessively hot during operation. If it is, reduce the operating time or check for proper voltage supply.
• Seal Replacement: If leaks occur around the valve body, the internal VITON seal may need replacement. Consult a qualified technician for internal component servicing.
