product description

	product model：	VQ67
	product name：	Pneumatic v-type regulating ball valve
	product feature:	Cylindrical spring preloaded with compensatory movable metal seat structure, reliable sealing performance. Ball core and valve seat will not produce jam or detach, long service life. The v-shaped cut on the ball core and the metal valve seat have shear effect, especially suitable for controlling high viscosity, including fiber, solid particles and slurry and other media. The structure of the paper manufacturing industry pulp is particularly superior. The flow capacity of the valve is large, the pressure loss is small, and the medium will not be deposited in the body cavity, the valve not only has approximately the same proportion of flow characteristics, adjustable range is large, the maximum adjustable ratio is 100:1, also has the function of accurate regulation and reliable positioning.
