What is the max pressure for a ball valve?
Maximum pressure range of ball valves
I. Conventional ball valve pressure range
Ordinary ball valves: The nominal pressure is usually 1.6-6.4MPa (such as PN16 corresponds to 16 bar/1.6MPa), which is suitable for conventional fluid control scenarios.
Medium and high pressure ball valves: Through enhanced material and structural design, some ball valves can withstand pressures of 16-50.0MPa, and are commonly used in industrial fields such as petroleum and chemical industry.
II. Ultra-high pressure ball valve performance
Customized products: Specially designed ultra-high pressure ball valves (such as gas or hydraulic special) have a maximum working pressure of 80-100MPa, and some models even support 700bar (70MPa) or higher pressure.
Extreme working conditions: In specific industrial scenarios, the ball valve can be extended to an upper pressure limit of 200MPa by optimizing sealing technology and material strength (need to be combined with specific design and certification standards). 3. Key influencing factors
Material: Stainless steel, alloy steel and other high-pressure resistant materials can improve pressure bearing capacity.
Sealing form: Metal hard seal or composite seal structure is more suitable for high-pressure environment.
Actuator: Pressure parameters need to be matched when paired with pneumatic or electric actuators.
4. Application scenario reference
Low-pressure scenario (≤1.6MPa): water treatment, HVAC system, etc.
High-pressure scenario (≥16MPa): oil pipeline, chemical reaction equipment, supercritical fluid control, etc.
Summary
The maximum pressure of ball valves varies significantly due to type and design:
Conventional ball valve: within 6.4MPa;
High-pressure ball valve: 50-100MPa (typical industrial grade);
Ultra-high-pressure custom valve: 200MPa (special working condition requirements).
When selecting, a comprehensive evaluation should be made based on the medium characteristics, temperature and certification standards.
