The FA72W-10P/R vacuum negative pressure safety valve is meticulously engineered for negative pressure systems operating at temperatures up to 200 ºC. Designed to maintain equilibrium within your system, this valve automatically activates to intake air when internal negative pressure surpasses permissible levels, ensuring the utmost safety. Conversely, when the internal pressure normalizes, the valve seals shut, safeguarding your equipment and system integrity. Typically, this product is deployed in standard non-negative pressure systems. In instances where the container’s release valve remains closed, generating negative pressure, the FA72W-10P/R safety valve promptly engages to avert any potential damage.
Our commitment to superior service extends beyond the sale. Onn Valve Co., Ltd. provides comprehensive valve maintenance and training for common fault troubleshooting. We offer both remote and on-site valve inspections, installation, and operational technical support. Technical quality consultations are responded to within 24 hours.

Additionally, lifetime after-sale service, along with a limited supply of free wear parts for the first 18 months, is guaranteed.
Q1: What is a safety valve?
1. Safety valves are critical components designed to preserve life, property, and the environment. They function by opening to relieve overpressure within a container or system and resealing once normal pressure levels are restored, preventing further fluid discharge.
2. Safety valves act as a vital last line of defense. Their operation must be reliable under all conditions, ensuring protection against overpressure. Unlike process valves or pressure regulators, they are engineered exclusively for overpressure protection and should be utilized accordingly.
Q2: How does a Safety Valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When the system pressure exceeds the safety valve's set limit, the valve disc lifts, discharging pressure due to the combined force of the medium pressure and spring force.
2. Keep Open: As the system pressure stabilizes within the set range, the spring maintains its position, keeping the valve open under consistent stress.
3. Close: When the system pressure drops below the valve's set threshold, the spring force prevails, sealing the valve disc under medium pressure, preventing any further pressure increase.
