The JA42Y series safety valve is an advanced safety solution specifically designed for pressure equipment, containers, or pipelines that operate at working temperatures of ≤ 300 ºC. Perfect for media such as air and oil, these valves serve as essential overpressure protection devices.
Onn Valve Co., Ltd. ensures comprehensive valve maintenance and offers training services to resolve common faults. We provide both remote and on-site valve reviews, along with installation and operation technical guidance. Technical consultations are addressed within 24 hours, and products come with an 18-month warranty (national standard applies). Our 24-hour technical support hotline is always available. During the warranty period, we offer various free after-sales services, lifetime support, and a limited supply of free spare parts for 18 months.
Q1: What is a safety valve?
1. Safety valves are crucial for protecting life, property, and the environment.
A safety valve is engineered to open and release excess pressure from a container or device, then re-close to prevent further fluid release once normal conditions are restored.
2. Serving as a critical safety device, the safety valve often acts as the final line of defense.
It is vital that safety valves operate reliably at all times and under any circumstances.
Safety valves are distinct from process valves or pressure regulators and should be used solely for overpressure protection.
Their primary function is singular: to provide overpressure protection.
Q2: How does a safety valve work?
The working principle of a safety valve can be delineated as follows:
1. Open: When system pressure surpasses the valve's set pressure, the valve disc opens under the pressure from the medium and the spring force to release excess pressure.
2. Keep Open: Once system pressure stabilizes within the set range, the spring maintains equilibrium, ensuring the system remains under control and the valve stays open.
3. Close: When system pressure drops below the valve's set pressure, the spring cannot lock the valve, causing the valve disc to close under medium pressure, thus halting any further pressure increase.
