Principle of Pressure regulating valve
- Kofloc Pressure regulating valve
- The pressure regulating valve (reducing valve) is used to control the pressure applied to the flow so that it will be constant during flow control.
Various types of valves are used according to application, as explained below.
1.
Pressure regulating valves are classified into general regulating valves and backpressure valves, and are represented by the symbols shown in the
figure.
The regulating valve controls the outlet side pressure so that it will be constant when the supply-side pressure changes. It is frequently used in the initial stage of a system.
Meanwhile, the back-pressure valve is a kind of continuous flow relief valve that removes gas to keep the primary-side pressure constant.

2.
The regulating valve controls the outlet-side pressure, and a pressure gauge is provided on the outlet side.
The KOFLOC 6600 is equipped with a pressure gauge port, and a pressure gauge is connected to the port in such a case.
The pressure at that port is practically equivalent to the outlet pressure; therefore, the pressure gauge can be connected to the outlet side.
