The FA72W-10P/R vacuum negative pressure safety valve is a precision-engineered solution ideal for negative pressure systems operating at temperatures up to 200 ºC. When the internal negative pressure surpasses the permissible threshold, the valve automatically opens to allow air intake; conversely, it shuts when the negative pressure reaches the safe level, safeguarding your equipment and system. Typically installed in standard non-negative pressure systems, this valve activates to prevent potential damage when the container's release valve isn't operational and negative pressure builds up.
Our company offers comprehensive valve maintenance and troubleshooting training services. We provide both remote and on-site technical guidance for valve review, installation, and operation. Technical quality consultations are answered within 24 hours. Our products come with an 18-month warranty period (as per national standards). We offer a 24-hour technical support hotline and various free after-sale services during the warranty period. Additionally, lifelong after-sale service and limited free supply of spare parts are available for 18 months.
Q1: What is a safety valve?
1. Safety valves are crucial for protecting life, property, and the environment. Designed to release excessive pressure from a container or device, they automatically re-close to prevent further fluid release once normal conditions are restored.
2. Serving as the final safeguard, safety valves must function reliably under all conditions, ensuring overpressure protection. These are not to be confused with process valves or pressure regulators, as their sole purpose is to provide overpressure protection.
Q2: How does a safety valve work?
The operational mechanism of a safety valve is outlined below:
1. Open: When system pressure exceeds the valve's set pressure, the valve disc opens due to the medium pressure and spring force, releasing excess pressure.
2. Keep open: If the system pressure stabilizes within the set limit, the spring maintains this state, keeping the valve open and the system under control.
3. Close: When system pressure falls below the valve's set pressure, the spring's inability to lock causes the valve disc to close, halting further pressure increase.
