Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere.
P id knife gate valve symbol.
Wey valve vl series 16 in.
P id symbols exist for all major components and lines such as valves vessels instruments pumps compressors and towers.
The isa s5 1 iso 10628 and bs 5070 cover the standardization of p id symbols and guide process engineers in their plant design activities.
So in addition to the valve design optimised for slurry media it is beneficial to have a knife made of acid.
Buttweld three way valve.
Used when a straight flow of fluid and minimum restriction is desired.
Excellent to be used as a control valve due to.
Many types of valves are required in a process plant for flow regulation or on off purpose.
These rugged gate valves can be used fully open or fully closed in high pressure applications.
Epoxy coated to help resist corrosion these blowoff valves feature a rugged stainless steel seat and disc hardened to 60 rockwell c for superior service in harsh environments.
Knife gate valves are designed to work in some of the most harsh environments typically having a sharpened blade to cut through heavy liquids.
