Product Q&A

Q:What materials are used for the valve parts?

The valve is constructed from robust materials such as carbon steel, stainless steel, or alloy steel. Specific parts include Body (Ht350, ZG1Cr18Ni9Ti), Nozzle (35, ZG1Cr18Ni9Ti), Adjusting ring (20Cr13, 1Cr18Ni9Ti), Disc (20Cr13, 1Cr18Ni9Ti), Spring (50CrVA), Stem (20Cr13), Adjusting bolt (45, 20Cr13), and Cap (ZG200-400). The sealing surface material is D507 Depositing stellite.

Q:What are the operational modes of the safety valve?

The valve features two configurable default states: normally open (NO) and normally closed (NC). Normally closed models remain sealed until triggered by overpressure, while normally open models maintain continuous flow or ventilation, closing only when pressure drops below a specified level or external actuation is applied.

Q:Is the pressure setting adjustable?

Yes, the valve is equipped with adjustable spring tension for precise pressure setting, enabling accurate matching to the system's maximum allowable working pressure (MAWP) to avoid under or over-actuation.

Q:What industries can use this valve?

The valve is ideal for chemical processing, power generation, water treatment, and pressure vessel systems. It is suitable for handling liquids, gases, and steam across diverse industrial applications.

Q:Does the valve require external power?

No, the valve is self-actuated and operates via spring force and system pressure. No external power is required, making it a fail-safe protection device.
