What are the main differences between a relief valve and a pressure reducing valve?
1 Answers
The main differences between a relief valve and a pressure reducing valve are as follows: 1. Pressure difference. The pressure reducing valve maintains constant pressure at the outlet. The relief valve maintains constant pressure at the inlet. 2. Outlet difference. When not in operation, the inlet and outlet of the pressure reducing valve are interconnected. When not in operation, the inlet and outlet of the relief valve are not connected. 3. Valve opening difference. In the non-working state, the valve port of the pressure reducing valve remains open. In the non-working state, the relief valve is normally closed. Additional information: 1. A plug valve is a rotary valve with a plug-shaped or cylindrical closing element. By rotating 90 degrees, the channel port on the plug aligns or separates from the channel port on the valve body, achieving opening or closing. 2. The plug of a plug valve can be cylindrical or conical. In cylindrical plugs, the channel is generally rectangular; in conical plugs, the channel is trapezoidal.
