意大利FIP手动隔膜阀，VM PVDF手动隔膜阀用于各种水处理系统
The VM type diaphragm valve is manually operated by a nonrising
hand-wheel. That means it does not change his height
during the rotation.
Metal spindle and sleeve ensure total reliability. The
compression bearing made of POM reduces friction and
consequent wear. The plastic spindle extension indicates the
valve position.
The valve design is compact and sturdy. The hand-wheel
has been designed without spokes, to provide
increased strength. Threaded inserts are moulded-in into the
bonnet, thus eliminating the need to drill holes, and also allowing
the body fixing bolts to be inserted from the bottom.
The above method allows a cavities- free bonnet, avoiding
dirt and impurities accumulation.
The diaphragm valve can be used with liquid and gaseous
fluids, and is particularly suitable for dirty or abrasive media.
It can be mounted in all positions. The hand-wheel operation,
and the diaphragm type sealing, allow a proper regulation and
reduce the water hammer.
