Hydraulic controlled eccentric half ball valve,eccentric half ball valve

Product Features

1. Its structure adopts the eccentric clamping principle to achieve the purposes of locking, regulating and closing through the transmission mechanism. The sealing pair is a metal surface ring band hard surface contact seal. The double eccentric structure ensures that the valve core is located in the ball storage chamber when opening, with a large flow cross-section and the valve not being eroded. When closing, the valve core is not eroded. When opening, the valve core surface gradually progresses along the valve seat, effectively removing the scaling obstacles. Achieve reliable sealing. It is particularly effective for the mixed-flow transportation of two-phase mixed flow where solids prone to scaling precipitate.

2. The hemispheres of the valve are made of bimetallic materials, and different alloys are surfacing welded on the base material. The valve seats are also surfacing welded accordingly and undergo special treatment. The sealing surfaces are combined into various types such as anti-corrosion, wear-resistant, and high-strength to meet the requirements of different occasions.

3. It is tightly sealed and can achieve zero leakage when transporting harmful gases.

4. The valve core of the sealing pair has a compensation allowance. When the valve is worn, it can still be reliably sealed by turning it slightly when closed, thus extending its service life. In addition, users can unscrew the compression nut. After adjustment or replacement, the valve seat can still be used, avoiding the drawback of the entire machine being scrapped after the valve seal fails.

The manual eccentric half ball valve utilizes an eccentric valve body, eccentric ball and valve seat. When the valve stem rotates, it automatically centers along a common trajectory. During the closing process, it closes tighter and tighter to achieve a good sealing effect. The ball and the valve seat of the valve are separated, eliminating the wear of the sealing ring and overcoming the problem of constant wear between the traditional ball valve seat and the ball sealing surface. The non-metallic elastic material is embedded in the metal seat, and the metal surface of the valve seat is well protected. This product is particularly suitable for media such as the steel industry, aluminum industry, fibers, fine solid particles, pulp, coal ash, petroleum gas, etc.
