As the name suggests these valves come with a drain port.
Angle seat valve symbol.
For each state of the valve a single square is drawn.
More ports and switching states are possible.
A 2 2 valve has two states open close and is therefore represented by two adjacent squares.
Needle valves are used as bleed valves or drain valves in the block and bleed assembly.

An angle seat piston valve is a pneumatically controlled valve with a piston actuator providing linear actuation to lift a seal off its seat.
To be used for pipes joining at an angle.
Working pressure pilot pressure diaphragm area springs.
Integrated block and bleed valve.
A 3 2 way valve has three ports and two switching states.
Angle seat piston valves are particularly suited to applications where high temperatures and large flow rates are required such as steam or water.
Many types of valves are required in a process plant for flow regulation or on off purpose.

The pipe lines are represented by lines connecting to each side of the valve symbol.
In each switching state a different port is closed off.
Valve symbols for p ids.
Various types of lines are used to represent different pipes tubes and hoses.
The seat is set at an angle to provide the maximum possible flow when unseated.
