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.
