Product working principle and use:
\nZMAW pneumatic film regulating butterfly valve input control signal (4-20mADC or 1-5VDC) air source can control operation, especially suitable for large caliber, large flow, thick slurry or boiler kiln flue gas control. It is suitable for the adjustment of suspended particle fluid and thick and turbid-like slurry fluid. Clean media, can choose the valve plate and soft seal (rubber ring, PTFE ring) to reduce leakage (up to 0.01%), high temperature and high pressure conditions can choose the three-eccentric hard seal valve body.
\nProduct structure features:
\n1, the valve has a simple and compact structure, convenient processing, easy to make large caliber, with self-cleaning effect, small resistance coefficient, large flow capacity.
\n2, with small size, light weight, rated flow coefficient and other advantages,
\n3, this series of products have standard type, high temperature type and sealed type three
\n4, when the pneumatic switch to manual, use the side loading handwheel mechanism method: pull out the positioning pin, pull the handle upward, the worm wheel and the worm mesh, press the positioning pin, rotate the handwheel can change the flow section. Manual switch to pneumatic, by the phase to pull the handle.<\/p>\n
