‑ Multiple end connections: flanged, BW butt‑weld
‑ Support manual, pneumatic, electric and hydraulic actuator assembly
‑ Compact and robust overall structure, long‑term stable operation
‑ Strict raw material inspection and full pressure test before delivery
‑ Support OEM, ODM and special working‑condition customization
‑ Complete test reports and technical documentation available
‑ Factory direct supply for refinery, energy and chemical projects
Applications
Mainly used in petroleum, natural gas, refinery, chemical plant, power plant and process pipeline system. Suitable for high‑pressure working occasions where valve online maintenance is required.
Forged Steel Top‑Entry Ball Valve completes opening and closing by 90‑degree rotation of ball core. When ball through‑hole aligns with pipeline channel, medium flows through; rotate 90 degrees to block passage and realize shut‑off. The top‑entry structure allows internal components to be disassembled and repaired from top of valve body without removing whole valve from piping.
