The Pilot Operated Safety Relief Valve is a groundbreaking structural safety valve, meticulously engineered for optimal performance. This cutting-edge valve is indispensable in critical sectors like petroleum, natural gas, chemical industry, electricity, metallurgy, and urban gas. It stands as the premier overpressure protection solution for pressure equipment, containers, and pipelines. Key advantages include transforming the direct spring action to the more sensitive indirect guide valve action, enhancing responsiveness significantly. The main valve, featuring a sleeve piston type, ensures high precision, exceptional repeatability, elevated reseating pressure, and superior sealing performance. It excels in discharging under high back pressure, operating stably and reliably, with the convenience of online adjustability. Moreover, its user-friendly design simplifies both operation and maintenance.
Onn Valve Co., Ltd. offers comprehensive valve maintenance and training services for troubleshooting common issues. We provide both remote and on-site valve reviews, along with installation and operational technical guidance. All technical inquiries will receive a response within 24 hours. Our products come with an 18-month warranty period, adhering to national standards. Additionally, we offer a 24-hour technical support hotline, various free after-sales services during the warranty period, lifetime after-sales service, and a limited supply of free wearing parts for the first 18 months.
Q1: What is a safety valve?
1. Safety valves are essential for safeguarding life, property, and the environment. Designed to open and alleviate overpressure in a container or device, a safety valve re-closes to halt further fluid release once normal conditions are restored.
2. Safety valves serve as a critical last line of defense in many systems. Ensuring their operation at all times and under all conditions is paramount. Unlike process valves or pressure regulators, safety valves are dedicated solely to overpressure protection and should not be misused.
Q2: How does a Safety Valve work?
The operation principle of a safety valve can be summarized as follows:
1. Open: When system pressure surpasses the safety valve's set pressure, the valve disc opens due to medium pressure and spring force, releasing excess pressure.
2. Keep open: Upon stabilization of system pressure within the set parameters, the spring achieves balance, maintaining an open state under system stress.
3. Close: When the system pressure falls below the set threshold, the spring fails to lock and seal, causing the valve disc to close under medium pressure, thereby ceasing pressure increase.
