Flow control
Self-operated valves
Self-operated control valves that operate by utilizing fluid pressure without the need for a power supply
Ratio control valve
Valve that keeps the pressure difference between two fluids constant
RCV series
Valve that uses a spring and bellows to adjust the fluid differential pressure between fluids on the reference and control sides to a constant level
Flow control valve
Valve for controlling the flow rate at a constant level even with pressure fluctuation
FCV series
Valve that uses bellows and diaphragm to adjust the flow rate to be constant even when the primary pressure (initial pressure) or the secondary pressure (service pressure) of the valve changes.
Motor-operated valves
Power-operated control valves that use an actuator to operate
Linear valve
Valve in which the valve opening is proportional to the flow rate
VOR series
Regulating valve for which Cv values can be easily adjusted in the field and in which the valve opening is proportional to the flow rate (linear).
