U.S. Solid 3/4" Motorized Ball Valve Instruction Manual

1. 서론

This manual provides essential information for the safe and efficient operation, installation, and maintenance of your U.S. Solid 3/4" Motorized Ball Valve. This electrical ball valve features NPT threading, operates on 85-265V AC, and includes a 2-wire auto-return setup. It is designed to minimize pressure loss and automatically cuts off power once fully open or closed, reducing the likelihood of overheating.

2. 안전 정보

경고:

• The valve is not explosion-proof and should not be used in environments with explosive or corrosive gases.
• Do not dismantle the actuator and valve when the power is on.
• It is recommended to install a filter to remove medium coarse impurities.
• Not for use underwater. Please enclose the valves in protective housing if permanently installed outside.
• Lead content: 3.05%. It cannot be used on drinking water.
• Ensure proper electrical connections are made to prevent short circuits or damage to the unit.
• 설치나 유지관리를 하기 전에는 반드시 전원을 분리하세요.

4. 설정 및 설치

4.1 Threading and Sealing

The valve features 3/4" Brass NPT threading, manufactured and measured according to National Pipe Thread standards. For a water-tight seal, it is recommended to apply PTFE (Teflon) tape to the male pipe threads before screwing the valve into place. Screw firmly to ensure a secure connection.

4.2 Electrical Wiring (2-Wire Auto Return)

This valve operates with a simple 2-wire auto-return setup. The valve largely de-energizes after opening and returns to a fully closed position if power is removed. It works effectively over an entire voltage 범위는 85-265V AC입니다.

Refer to the wiring diagram below for proper connection. The red wire can be connected to either the positive or negative pole, with the green wire connected to the opposite pole. Once energized, the valve will open and remain open. If power is disconnected, the valve will close.

5. 사용 설명서

The U.S. Solid Motorized Ball Valve is designed for straightforward operation. It will open or close the valve in 3-5 seconds.

• 밸브 열기: Apply power to the valve. The motor will actuate the ball to the open position. Once fully open, power consumption becomes nominal (near zero).
• 밸브 닫기: Disconnect power from the valve. The auto-return mechanism will automatically move the ball to the fully closed position. Once closed, power consumption is zero.

This auto-cut-off feature makes it a suitable alternative to solenoid valves for applications requiring the valve to remain open for extended periods without continuous power draw.

6. 유지관리

The U.S. Solid Motorized Ball Valve is designed for durability and minimal maintenance. Its lifespan is rated for 80,000-100,000 cycles.

• 정기 검사: Periodically check for any signs of leaks around the connections. Ensure the wiring remains secure and free from damage.
• 청소: Keep the exterior of the valve and actuator clean from dust and debris to prevent interference with moving parts or heat dissipation.
• 환경 보호: If installed outdoors, consider additional protective housing to shield the valve from harsh weather conditions, as it is rated IP65 (dust-tight and protected against water jets).

7. 문제 해결

• 밸브가 작동하지 않습니다:
  • Check power supply: Ensure the valve is receiving the correct voltage(85-265V AC).
  • Inspect wiring: Verify all connections are secure and correctly wired according to the diagram in Section 4.2.
  • Check for obstructions: Ensure there are no physical obstructions preventing the ball from turning.
• Valve Leaking:
  • Check threaded connections: Ensure PTFE (Teflon) tape was applied correctly and connections are tightened sufficiently.
  • Inspect for damage: Look for any visible cracks or damage to the valve body.
• 작동 중 비정상적인 소음:
  • This may indicate internal wear or an obstruction. If the noise persists or affects performance, contact customer support.
