Flow control valve [FCVD type]

Diaphragm-type flow control valve using a diaphragm for the valve drive part.

Features

This valve is a flow control valve capable of controlling an extremely small amount of liquid, 2L per hour at minimum, to a constant amount.
The operating principle is the same as that of the piston type.
It is especially ideal for medium- and small-sized furnaces and combustion equipment that use kerosene.
