2. 안전 정보

Please read all safety warnings and instructions carefully before installing or operating this valve. Failure to do so may result in property damage, injury, or death.

  • Lead Exposure Warning: 이 제품은 캘리포니아 주에서 암과 선천적 결함 또는 기타 생식적 피해를 유발하는 것으로 알려진 납을 포함한 화학 물질에 노출될 수 있습니다. 자세한 내용은 다음을 방문하세요. www.P65Warnings.ca.gov.
  • Non-Potable Water Use: Due to the chemical composition of brass, this valve should NOT be used with projects involving drinking water or other potable water systems. It is not allowed to be installed in potable water pipelines.
  • 듀티 사이클: This valve is NOT a continuous duty valve. It should NOT be in continuous use for more than 8 hours in a single cycle. Exceeding this duration will shorten the valve's lifespan and may cause the coil to burn out. If continuous duty is required, consider U.S. Solid Motorized Ball Valves.
  • 전기 안전: Ensure all electrical connections are made by a qualified professional and comply with local electrical codes. Disconnect power before installation or maintenance.
  • 압력 한계: Do not exceed the maximum operating pressure of 101.52 PSI (7 Bar) for air/water or 72.5 PSI (5 Bar) for oil.
  • 온도 제한: Operate within the specified temperature range of -10°C to 120°C (14°F to 248°F).

3.4 Solenoid Valve Types

This valve operates on a direct-acting principle, which means it opens by lifting the plunger with electromagnetic force and closes with a spring. This design is suitable for low-pressure, small-flow, and vacuum applications, offering fast response.

5. 설치

Proper installation is crucial for the safe and efficient operation of the solenoid valve.

  1. 준비: Ensure the system is depressurized and drained before installation. Clean all pipe threads to remove debris.
  2. 나사산 밀봉제: Apply an appropriate thread sealant (e.g., PTFE tape or pipe dope) to the male pipe threads. Ensure the sealant is compatible with the media being controlled.
    3. Close-up image showing application of thread sealant tape to pipe threads

  3. 설치: Install the valve in the desired position, ensuring the flow direction matches the arrow on the valve body. The valve can be mounted in any orientation, but for optimal performance and lifespan, it is generally recommended to mount the coil vertically upwards.
  4. 조임: Hand-tighten the valve onto the pipe, then use a wrench to tighten an additional 1 to 2 turns. Do not overtighten, as this can damage the valve or threads.
  5. 여과법: It is recommended to install a filter upstream of the solenoid valve to prevent debris from entering and potentially obstructing the valve's operation. (Filter not included).

  6. 전기 연결: Connect the valve to a 24VAC power source. Ensure the power supply matches the valve's voltage rating. All electrical work should be performed by a qualified electrician and adhere to local codes.
  7. 누출 확인: After installation, slowly pressurize the system and check for any leaks at the connections.

6. 운영

This U.S. Solid solenoid valve is a Normally Closed (N.C.) type. Its operation is straightforward:

  • 비활성화 상태: When no electrical power is supplied to the coil, the valve remains closed, preventing fluid flow.
  • 활성화 상태: When 24VAC electrical power is applied to the coil, the electromagnetic force lifts the plunger, opening the valve and allowing fluid flow.
  • 응답: The valve opens and closes rapidly, typically in less than 1 second.

Important Operating Note: As stated in the safety section, this valve is not designed for continuous duty. Avoid keeping the valve energized for more than 8 hours in a single cycle to prevent overheating and premature failure of the coil.

7. 유지관리

Regular maintenance helps ensure the longevity and reliable performance of your solenoid valve.

  • 정기 검사: Periodically inspect the valve for any signs of leaks, corrosion, or damage to the wiring.
  • 청결: Ensure the area around the valve is kept clean and free of debris that could interfere with its operation.
  • Coil Condition: Check the solenoid coil for any signs of overheating (discoloration, melting). If detected, review operating conditions, especially the duty cycle.
  • 씰 무결성: While VITON seals are highly durable, extreme conditions or incompatible media can degrade them over time. If leaks occur, inspect the seal for damage.

Always disconnect power and depressurize the system before performing any maintenance.
