The FA72W-10P/R vacuum negative pressure safety valve is a vital component designed for negative pressure systems operating at temperatures of up to 200ºC. When the internal pressure of the container surpasses the allowed negative pressure, this valve automatically opens to intake air. Conversely, when the internal pressure returns to acceptable levels, the FA72W-10P/R automatically closes, thereby safeguarding both equipment and systems. Typically installed in standard non-negative pressure setups, this valve activates to protect against damage if the system's release valve fails to open and negative pressure builds up.
Our company is committed to exceptional after-sales support, offering routine valve maintenance and training for common fault troubleshooting. We provide both remote and on-site valve inspections, installation, and operational guidance. Technical inquiries are addressed within 24 hours. We offer an 18-month product warranty (in accordance with national standards), and a 24-hour technical support hotline. Throughout the warranty period, we provide various free after-sales services and a limited supply of free replacement parts for 18 months. Lifetime after-sales service is also available.
Q1: What is a safety valve?
1. Safety valves serve the crucial purpose of protecting life, property, and the environment. Designed to release excess pressure from a container or device, these valves reopen to prevent further fluid release once normal conditions are restored.
2. As a critical safety device, safety valves often represent the last line of defense. Ensuring their reliability under all conditions is paramount. Unlike process valves or pressure regulators, safety valves should only be used for overpressure protection.
Q2: How does a safety valve work?
The operating principle of a safety valve is as follows:
1. Open: When system pressure exceeds the valve's set pressure, the valve disc opens due to medium pressure and spring force, releasing the excess pressure.
2. Keep open: As the system pressure stabilizes within the set limit, the spring maintains stability, keeping the valve open and managing the stress.
3. Close: When system pressure falls below the valve's set pressure, the spring fails to lock and seal. Consequently, the valve disc closes under the medium pressure, ceasing any further pressure increase.
