QT450 Split Ball Valve Eccentric Half Ball Valve Against Pressure Manual 1Cr13

Equipped with eccentric half ball valve against pressure manual

Product Introduction

Mounted eccentric half ball valve using eccentric body, eccentric ball and seat, stem for rotation movement in the common track automatic centering, closing process is tighter, fully achieve good sealing purpose. The ball and seat of the valve are completely separated, eliminating the wear of the sealing ring and overcoming the problem that the traditional ball seat and the ball sealing surface are always worn. Non-metallic elastic materials are embedded in the metal seat, and the metal surface of the seat is well protected. This product is especially suitable for steel industry, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.

Mounted eccentric half ball valve product features

1, the structure adopts the eccentric tightening principle through the transmission mechanism to achieve the purpose of gate tightening, adjustment and closing, the sealing pair is the metal surface ring with hard surface contact seal, double eccentric structure in the opening of the valve spool is located in the ball room, the flow section is large, and the valve is not scoured, closed the valve spool is not scoured, open the valve spool spherical gradually along the seat, effectively remove the scale barrier, Achieve reliable sealing. It is especially effective for the mixed flow transportation of two-phase mixed flow with easy scaling and solid precipitation

2, the hemisphere of the valve with bimetal, base metal surfacing on different alloys, the valve seat is also made corresponding surfacing through special treatment, sealing surface combination into anti-corrosion, wear, high strength and other types, to meet the needs of different occasions

3, tight seal, conveying harmful gas can reach zero leakage

4. The spool of the sealing pair has a compensation amount. When the valve is worn, it can turn a little when closed to ensure reliable sealing and prolong the service life. In addition, the user will screw off the compression nut, adjust or replace the valve seat is still available to avoid the failure of the valve seal, the problem of the whole set scrap.

5, the mounted eccentric half ball valve structure is above a cover, can be repaired in the pipeline, convenient and labor-saving.
