5. 설정 및 설치

Installation should only be performed by a qualified plumber or technician. Adhere to all local plumbing codes and regulations.

1. 시스템 감압: Before beginning installation, ensure the water system is completely shut off and depressurized. Drain any residual water from the system.
2. 위치 선택: Install the relief valve in an accessible location on the storage tank or water equipment, typically at the highest point or as specified by the tank manufacturer.
3. 스레드 준비: Apply appropriate thread sealant (e.g., PTFE tape or pipe dope) to the 3/4" male NPT inlet threads of the relief valve.
4. 연결: Carefully thread the valve into the designated port on the storage tank. Tighten securely using a wrench, but do not overtighten, which can damage the valve or tank.
5. 배출 배관: Connect appropriate discharge piping to the 3/4" female NPT outlet. The discharge pipe must be sized correctly, sloped for drainage, and terminate in a safe location where discharged water will not cause damage or injury. Do not cap or restrict the discharge pipe.
6. System Repressurization: Slowly repressurize the system and check for leaks at all connections.
7. 기능 확인: Verify that the valve is not leaking and that the system pressure is within acceptable limits for the valve's setting.

6. 운영

The Zurn RV 150 PSI CA# FWL-2 Water Equipment is an automatic pressure relief valve. It is designed to open and discharge water when the system pressure exceeds its factory-set limit (e.g., 150 PSI for this model). This action prevents excessive pressure buildup within the storage tank, protecting the tank and connected components from potential damage.

Under normal operating conditions, the valve remains closed. If the valve discharges water, it indicates an over-pressure condition in the system. Investigate the cause of the over-pressure immediately.

7. 유지관리

Regular inspection and maintenance are crucial for the continued safe operation of the relief valve. It is recommended to have the valve inspected annually by a qualified professional.

• 시각적 검사: Check the valve and discharge piping for any signs of corrosion, leaks, or damage.
• 수동 테스트: Periodically, and with caution, manually operate the relief valve by lifting the test lever (if present) to ensure it opens and closes freely. Allow a small amount of water to discharge, then release the lever. If the valve does not discharge or does not close completely, it may need replacement.
• 대사: Relief valves have a service life and may require replacement after several years of service, especially if signs of wear, leakage, or malfunction are observed. Consult a professional for replacement recommendations.

8. 문제 해결
