China Semi-ball Valve supplier Features and advantages

When fully open, the water loss is zero, the flow channel is completely unobstructed; the inner cavity is automatically cleaned, the valve core rotates 90 degrees, the inner cavity of the valve body is automatically flushed, the sundries in the medium are cleaned, and the medium can not be deposited in the valve cavity. The ball is hemispherical circulation has the highest CV value, and enhance the system efficiency of the pump, and the lowest degree of abrasion. Because the ball is hidden on one side of the valve cavity, the flow passage is formed without flow resistance, and the eccentric eccentric shaft is fixed firmly.
