Okaya FCVD Type Flow Control Valve
Manufacturer: Okaya Seiritsu Engineering Co., Ltd.
Model: FCVD Type
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.
