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.
Normally closed gate valve.
Withstand extreme pressure temperature and high volume flow.
Used for high flow capacity.

Many types of valves are required in a process plant for flow regulation or on off purpose.
The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface.
Diverting 3 way valve.
Normally closed ball valve.
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.
Here is a list of symbols for various types of valves used in process industry.
Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere.
