Introducing our Pilot Operated Safety Relief Valve - a trailblazing innovation in safety valve technology. Perfect for industries such as petroleum, natural gas, chemical, electricity, metallurgy, and urban gas, this valve stands as the ultimate safeguard against overpressure for pressure equipment, containers, and pipelines. Distinguished by its switch from direct spring action to an indirect guide valve action, it boasts heightened sensitivity and precision. The main valve features a sleeve piston design, ensuring unparalleled action accuracy, repeatability, reseating pressure, and sealing performance. Capable of operating under high back pressure and delivering consistent, reliable performance, it is adjustable online and remarkably user-friendly in terms of both operation and maintenance.
Our commitment extends beyond the sale with comprehensive after-sales services. Onn Valve Co., Ltd. offers routine valve maintenance and training for common troubleshooting. We provide both remote and on-site technical guidance for valve review, installation, and operation. Responding to technical quality consultations within 24 hours, we guarantee an 18-month product warranty consistent with national standards. Our 24-hour technical support hotline ensures assistance whenever needed. During the warranty period, we offer various free after-sales services and lifetime support, including a limited supply of free wearing parts for 18 months.
Q1: What is a safety valve?
1. Safety valves play a crucial role in protecting life, property, and the environment. They are engineered to open and release excess pressure from a container or device and automatically reclose to prevent further fluid release once normal conditions are restored.
2. Serving as a critical safety measure, safety valves act as the last line of defense. They must be operational at all times and under all conditions. It's imperative to remember that safety valves are not process valves or pressure regulators and must only be used for overpressure protection.
Q2: How does a Safety Valve work?
The operational principle of a safety valve is summarized as follows:
1. Open: When the system pressure surpasses the valve's set pressure, the valve disc opens under the combined force of the medium pressure and spring force, thereby releasing excess pressure.
2. Keep open: Once the system pressure stabilizes within the set parameters, the spring maintains its position, and the safety valve remains open, allowing the system to stay under control.
3. Close: When the system pressure drops below the valve's set pressure, the spring no longer locks, causing the valve disc to close under medium pressure, halting any further increase in medium pressure.
