Relief valve, pressure reducing valve, and sequence valve. These pressure valves have similar schematic symbols, but the purpose and behaviour of each valve.
DIFFERENCE BETWEEN PRESSURE REDUCING VALVE AND PRESSURE RELIEF VALVE Mechanical Engineering
December 21, 2017. A piping and instrumentation diagram (P&ID) is a graphic representation of a process system that includes the piping, vessels, control valves, instrumentation, and other process components and equipment in the system. The P&ID is the primary schematic drawing used for laying out a process control system's installation.
Valve Sign Symbols The Engineering Concepts
There are dedicated symbols for a gate, globe, plug, and ball valves which I will explain to you in minutes. Similarly, the next two symbols are for three-way and four-way valves. It can be a plug or ball valve. The subsequent two symbols are a check valve and a stop check valve. These check valves can be swing check or lift check valves.

P&ID Symbols for Valves Many types of valves are required in a process plant for flow regulation or on/off purpose. Type of valve employed depends on nature of fluid, flow control required, operating pressure and temperatures as well as surround atmosphere. Here is a list of symbols for various types of valves used in process industry.

Here are the most common symbols used to identify this type of valves: >> The symbol commonly used to represent a pressure reducing valve in hydraulic systems is as follows: It's a general symbol. >> The hydraulic symbol for a one-way pressure reducing valve: >> Symbol of a differential reducing valve between the pressures of 1 and 2.

Pressure reducing valve symbol icon Royalty Free Vector
A pressure-reducing valve is a self-operating valve that is used to reduce any excess pressure in a system. Sometimes this valve is also known as pressure reducing regulator. The basic function of pressure-reducing valves is to reduce higher pressure into lower. They are commonly used in water, steam, and oil & gas industries.

Last updated: May 16, 2020 Pressure reduction valve is a control valve that lowers the inlet pressure of the fluid and gives the desired pressure at the output. The pressure reduction valve maintains a constant pressure in a part of the system that operates at a pressure lower than the normal system pressure.

The lower symbol indicates a remote pilot operated valves. This valve will still open if the supply pressure increases, via the same dashed line, but will also open due to pressure applied on the remote line X. Note also how the drain line Y can be refereneced to a more stable drain line pressure. Learn more about pressure relief valves

In Hydraulic Symbology 101 ( read it here first ), I covered the basic square used for pressure valves and also showed the most stripped-down versions of the two most commonly used pressure valve symbols, the relief valve and the pressure reducing valve.
Distinguishing Regulators and Reducing Valves
Symbols The air valve is called a regulator, but even though the name suggests that it can either increase or decrease the pressure, like the pressure reducing valve, it can only decrease the inlet pressure. In a pneumatic system, the regulator is the primary pressure control.

This device protects the pilot from over pressurization. It blocks the downstream pressure when it exceeds the adjustable limit and reopens when inlet pressure drops below the limit. The downstream pressure in the pilot tells the valve what to do next. With the set point at 150 PSI, this pilot will keep the valve open until 150 PSI is reached.
