Eccentric Half Ball Valve

Description

The Eccentric Half Ball Valve uses a hemispherical (half-ball) plug mounted on an eccentric shaft. On opening, the plug swings clear of the seat in a cam-like motion, so the sealing surfaces do not rub, and the open valve offers an unobstructed, full-bore passage. This makes it particularly suited to sewage, slurry and fibrous media that would clog or wear conventional valves.

Technical Specifications:

• Pressure Class: PN10 / PN16
• Size Range: DN50 – DN1200
• Applicable Medium: Sewage, slurry, raw water, pulp, media with suspended solids
• Operating Temperature: -10°C to 120°C

Main Parts and Materials:

Key Product Features:

1. Eccentric Action: Plug lifts away from the seat on opening, eliminating friction and wear.
2. Self-Cleaning: Scraping action at closure removes deposits from the seat.
3. Full Unobstructed Bore: No cavity for solids to collect; resists clogging.
4. Tight Shut-Off: Wedge-type closing force increases sealing pressure.
5. Low Torque: Gear, electric or pneumatic operation with small actuators.

Applications:

Ideal for Wastewater Treatment Plants, Sludge Lines, Mining Slurry, and Pulp & Paper. Specifically suited for dirty or abrasive media where gate and butterfly valves suffer from clogging.
