Eccentric Half-Ball Valve

Product Features

● Eccentric Structure: The valve core and stem are offset, allowing the half-ball to disengage from the seat smoothly without friction.
● Self-Cleaning and Anti-Blocking: The eccentric motion minimizes sediment buildup and ensures smooth flow in dirty or viscous media.
● Metal or Soft Seal Options: Available in hard-faced metal sealing or resilient sealing for different process conditions.
● Low Operating Torque: Smooth rotation with minimal friction between sealing surfaces.
● High Pressure Capability: Supports multi-standard pressure classes, suitable for demanding service conditions.
● Tight Shut-off Performance: Ensures zero leakage in both flow directions when fully closed.

Product Overview

Product Overview

The Eccentric Half Ball Valve is a high-performance valve that combines the sealing advantages of a ball valve with the structural strength of a plug valve.

It features an eccentric half-ball design where the ball and valve seat separate without friction during opening and closing, ensuring low torque, wear resistance, and long service life.

This valve provides reliable metal-to-metal or soft sealing options, suitable for high-pressure, high-temperature, and slurry or particulate media applications in power, petrochemical, and water treatment industries.
