The A48Y type safety valve is specifically engineered for equipment or pipelines handling steam, air, and various other media, operating at temperatures ≤350°C. Serving as a paramount overpressure protection device, this valve springs into action whenever the pressure surpasses the permissible threshold. It opens up effortlessly to discharge the excess pressure entirely. Once the pressure dips to the designated safe level, the valve automatically seals shut, thereby safeguarding the integrity of both equipment and pipelines.
At Onn Valve Co., Ltd., we are committed to ensuring the longevity and optimal performance of your valves. Our comprehensive after-sales service encompasses routine maintenance, troubleshooting training, and both remote and on-site technical support for valve review, installation, and operation. We pledge to respond to all technical quality inquiries within 24 hours. Every product comes with an 18-month warranty as per national standards. Additionally, we provide a 24-hour technical support hotline, complimentary after-sale services during the warranty period, lifetime after-sales support, and a limited supply of free wearing parts for 18 months.
Q1: What is a safety valve?
1. The primary function of safety valves is to safeguard life, property, and the environment. They are ingeniously designed to open and release excess pressure from containers or devices, and to re-seal, preventing further fluid release once conditions normalize.
2. A safety valve acts as a critical safety mechanism, often serving as the final defensive barrier. It is imperative that safety valves remain operational under all scenarios. They are distinct from process valves or pressure regulators and should be exclusively used for overpressure protection.
Q2: How does a safety valve work?
The operation of a safety valve can be succinctly described as follows:
1. Open: When system pressure exceeds the pre-set threshold, the valve disc opens due to the combined effect of medium pressure and spring force, thereby releasing the excess pressure.
2. Keep Open: Once the system pressure stabilizes within the set limits, the spring steadies, and the valve remains open as the system remains under controlled stress.
3. Close: When the system pressure falls below the pre-set threshold, the spring loses its hold, allowing the valve disc to close under the influence of the medium pressure, thus ceasing any further pressure increase.
