Certified for use in potable water applications these full port valves act as a shutoff and can be used fully open or fully closed in water and compressed air applications.
Water gate valve symbol.
A gate valve also known as a sluice valve is a valve that opens by lifting a barrier gate out of the path of the fluid gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
Used when a straight flow of fluid and minimum restriction is desired.
Now when you look at the symbol on drawing it just gives you an indication that some kind of valve is used but it will not provide you with information about the type of valve whether it is a gate globe or plug type valve.
Many types of valves are required in a process plant for flow regulation or on off purpose.
There are dedicated symbols for a.
Gate valves are characterized by a gate figures 4 49 and 4 50 that closes in a plane perpendicular to the flow of fluid they are used primarily for on off nonthrottling service.
Standard detail created date.
Shearing of high velocity flow will cause a partially open disk to vibrate and chatter which will damage the seating surfaces and prevent a tight seal.

The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface.
Withstand extreme pressure temperature and high volume flow.

These symbols are generic in nature for example the first symbol of a valve.
Used for high flow capacity.
Normally closed ball valve.
Diverting 3 way valve.
Here is a list of symbols for various types of valves used in process industry.
Excellent to be used as a control valve due to.
Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere.
Normally closed gate valve.
