Three-way flow regulating valve
Overview
This three-way flow regulating valve is a
energy-saving type flow regulating valve that
has both the meter-in flow regulating
function and pressure regulating function.
By using this valve, only the flow rate
corresponding to the opening setting is
supplied to the load side and excess oil is
bled off. At that time, as the inlet side
pressure is kept slightly higher than the load
pressure, energy consumption is
substantially reduced.
Type indication
Features
1. As the restriction part is of sharp-edged
orifice structure, high-precision temperature
compensation can be obtained.
2. As the handle key is adopted for the adjusting
part, the flow rate does not change even if you
touch the handle by mistake other than during
adjustment.
3. The three-way flow regulating valve with a
relief valve for restricting the maximum
pressure or the valve with a port for vent
unloading is available.
