Applications
Flanged ball valve can be used in various situations, including water conveyance pipelines, heating distribution pipelines, high-temperature and high-pressure media conveyance pipelines in steel mills, and petroleum pipelines.
Basic Information
- Size Range
- DN15-DN200
- Temperature Range T
- 0-100℃
- Maximum Allowable Operating Pressure PN
- 1.0-2.5Mpa
- Pressure Rating
- 1.5-3.75Mpa (Shell)
1.1-2.75Mpa (Seal)
- Applicable Media
- Freshwater, seawater, air, weak acid-base, and so on.
Features
- Wear-resistant: The valve core is made of spray welding of alloy and the O-ring is made of overlay welding of alloy, permitting minimal wear during valve operation (with a hardness coefficient of 65-70).
- Excellent sealing performance: Flanged ball valves are manually ground to ensure a perfect fit between the valve core and the O-ring, providing reliable sealing performance.
- Light operation even when external forces exceed the pre-tension force of the spring.
