FAQ
Safety Valve FAQs for Selection and Specification
How do I choose the right safety valve for my application?
The right safety valve depends on your service medium, set pressure, temperature, back pressure, connection type, and applicable standard. For most projects, selection starts with the process conditions first, then moves to valve type, materials, and documentation review.
What is the difference between GB and ASME safety valve series?
GB and ASME safety valve series differ in standard framework, dimensional references, code systems, and project compliance requirements. The right choice depends on the market, project specification, and the standard your system must follow.
What operating range can your safety valves cover?
Zobai safety valves cover sizes from DN10 to DN600, pressure ratings from 0.6 to 42 MPa, and service temperatures from -196°C to 570°C, depending on the model and application. Specific selection should always be confirmed against the working conditions and product data.
Which industries and systems are your safety valves used in?
Zobai safety valves are used in oil and gas, petrochemical, chemical, technical gas, LNG/LPG, pharmaceutical, food and beverage, HVAC, shipbuilding, and other industrial process systems. Application suitability depends on the operating medium, temperature, pressure, and hygiene or compliance requirements.
What technical documents should I review before requesting a quotation?
Before RFQ, buyers usually review the datasheet, applicable standard, model or code reference, materials, dimensions, and key selection data such as set pressure and operating conditions. Having these documents ready helps speed up technical review and quotation accuracy.
