ZSH Shanghai Valve Manufzcturing Co.,LTD.

The compensatory movable metal seat structure cylindrical spring preload, reliable sealing performance. Ball - the seat will not generate the card resistance or detachment, long service life. The V shaped notch on the ball core has a shearing action with the metal base, and is especially suitable for high viscosity, containing fibers, solid particles and slurry and the like. Structure of the paper pulp industry is particularly superior. Valve flow rate, pressure loss is small, the media will not be deposited in the body cavity, the valve is not only similar to the surface area ratio of the flow characteristics, adjustable range, the maximum adjustable ratio of 100:1. It also has the function of precise adjustment and reliable positioning. The valve series can be configured with a variety of driving devices. V type adjusting ball valve, adjusting ball valve, ball valve.
