U.S. Solid Motorized Ball Valve USS-MSV00077 Instruction Manual

1. 서론

This manual provides essential information for the safe and effective installation, operation, and maintenance of your U.S. Solid Motorized Ball Valve, Model USS-MSV00077. This 1/4-inch stainless steel valve features a full port design, operates on 9-24V AC/DC power, and includes a 2-wire auto return mechanism, functioning as a normally open valve.

2. 안전 정보

Please read and understand all safety instructions before installing or operating the valve. Failure to follow these instructions may result in property damage, injury, or death.

• 전기 안전: Ensure power is disconnected before performing any wiring or maintenance. All electrical connections should be made by a qualified professional and comply with local electrical codes.
• 압력 안전: Verify that the system pressure does not exceed the maximum operating pressure specified for this valve. Depressurize the system before installation or removal.
• 온도: Do not operate the valve outside its specified temperature range.
• 화학적 호환성: Ensure the valve material (304 stainless steel) is compatible with the fluid being controlled to prevent corrosion or failure.
• 설치: 밸브는 적절한 환기가 가능하고 유지보수를 위한 접근성이 좋은 위치에 설치하십시오.

3. 제품 오버view 및 기능

The U.S. Solid Motorized Ball Valve is designed for reliable fluid control in various applications. Key features include:

• 내구성 있는 구조: Manufactured from 304 stainless steel for enhanced safety and reliability, offering an estimated life expectancy of 80,000 to 100,000 cycles.
• Full Port Design: Features a 1/4-inch full port bore, minimizing pressure loss through the valve.
• NPT Threading: Equipped with 1/4-inch quality brass NPT threads, manufactured to National Pipe Thread standards.
• 와이드볼tag전자 범위: Operates effectively on 9-24V AC/DC power.
• 빠른 작업: Opens or closes the valve within 3-5 seconds.
• 리미트 스위치 : Incorporates a limit switch to minimize power consumption once the valve is fully open or closed.
• 2-Wire Auto Return: Simple two-wire connection. The valve largely de-energizes after closing and automatically returns to the fully open position if power is removed.
• IP65 Enclosure Rating: 먼지 유입 및 모든 방향에서 분사되는 저압수로부터 보호해 줍니다.

5. 설정 및 설치

밸브의 성능과 수명을 위해서는 올바른 설치가 매우 중요합니다.

5.1 기계 설치

1. 파이프 끝 준비: Ensure pipe ends are clean and free of debris.
2. 실란트 바르기: For NPT threads, apply appropriate thread sealant (e.g., PTFE tape) to the male pipe threads to ensure a watertight seal.
3. Thread Valve: Carefully thread the valve onto the pipe. Tighten firmly but do not overtighten, which can damage threads or the valve body.
4. 정위: The valve can be installed in any orientation, but ensure the actuator is accessible for wiring and inspection.

5.2 Electrical Wiring (2-Wire Auto Return)

This valve features a 2-wire auto return setup. It is a normally open valve, meaning it is open when no power is applied. Applying power will close the valve, and removing power will cause it to return to the open position.

• 전원: Connect the valve to a 9-24V AC or DC power source.
• 배선: Connect the two wires from the valve to your power source. The valve will operate regardless of polarity for DC connections.
• 작업: When power is applied, the valve will move to the closed position. When power is removed, the valve will automatically return to the open position.

6. 사용 설명서

The U.S. Solid Motorized Ball Valve is designed for straightforward operation based on its 2-wire auto return, normally open configuration.

• Normally Open State: When no electrical power is supplied to the valve, it remains in the fully open position, allowing fluid to flow through.
• 밸브 닫기: To close the valve, apply 9-24V AC/DC power to the two wires. The internal motor will actuate the ball, moving it to the closed position within 3-5 seconds. Once fully closed, the internal limit switch will cut power to the motor, preventing overheating.
• Opening the Valve (Auto Return): To open the valve, simply remove the electrical power supply. The valve's auto return mechanism will automatically move the ball back to the fully open position.

7. 유지관리

The U.S. Solid Motorized Ball Valve is designed for minimal maintenance. However, periodic checks can help ensure optimal performance.

• 시각적 검사: Regularly inspect the valve for any signs of leaks, corrosion, or physical damage to the valve body or actuator housing.
• 전기 연결: 모든 전기 연결이 안전하고 부식되지 않았는지 확인하십시오.
• 액추에이터 기능: Periodically cycle the valve (open and close) to confirm smooth operation and proper response to power signals.
• 청소: Keep the exterior of the actuator clean and free of excessive dust or debris. The IP65 rating provides protection against dust and water jets, but harsh chemicals should be avoided.
• 사용자가 수리할 수 없는 부품: The actuator mechanism contains no user-serviceable parts. Do not attempt to disassemble the actuator, as this will void any warranty and may cause damage.
