WP series pneumatic V type ball valve
New-generation WP series V type ball valve is one kind of high-class control valve of quarter-turn structure. Valve core is designed to be a notch with special shape V. It has accurate shutoff physical property and control function, big rated flow coefficient, great adjustability and small volume, which can be used to control turbid liquid with fibrous or tiny solid particles and solid state particles.
According to national valve standard series, WP series ball valve can be widely used in various industrial departments, such as paper making, petrifaction, metallurgy, sugaring, electric power, waterpower, environmental protection and pharmacy and so on, to meet user’s final technological requirements. The special “valve core, valve body and valve seat structure” of WP series can be used in occasions which need frequent working and can ensure rigorous close under minimum differential pressure.
There are diversity materials for WP series ball valves to select. So users can select best configuration according to their technological needs.
