Worm Gear Operated Trunnion Mounted Ball Valve

The worm gear operated trunnion mounted ball valve is a pipeline ball-valve assembly with a worm gear operator and trunnion-mounted construction. It is intended for project-led valve selection where bore, end connection, materials, pressure class, sealing arrangement, and operating torque are confirmed against approved documentation.

Six Valve Categories From One Plant

Butterfly, ball, gate, globe, check and hydraulic control: six valve categories from one plant.

Valve Manufacturing Process
  1. 01Design each valve in CAD before it reaches the shop floor.
  2. 02Identify and mechanically test material before machining starts.
  3. 03Machine valve components on CNC lathes and boring machines.
  4. 04Spray-weld the seating surface with plasma equipment.
  5. 05Inspect welds and castings with non-destructive and ultrasonic testing.
  6. 06Pressure-test the shell and seat of every valve before dispatch.
