Knife Gate Valve Symbol

Utilizing a sharp beveled edge a knife gate was ideally designed to cut through the stringy pulp encountered in the pulp and paper industries.

Knife gate valve symbol.

Knife gate valves were originally designed for use in the pulp and paper industry. Excellent to be used as a control valve due to. The first is for butt welding ends second is for flanged end valve and the third one is for socket end connection. Used when a straight flow of fluid and minimum restriction is desired.

Now see the p id symbol for the gate valve. It is a modification of a generic valve symbol by inserting a vertical line between two triangles. Used for high flow capacity. Three symbols shown below are the gate valve symbols used in isometric drawings.

Normally closed gate valve. Many types of valves are required in a process plant for flow regulation or on off purpose. Piping and instrument diagram standard symbols detailed documentation provides a standard set of shapes symbols for documenting p id and pfd. Normally closed ball valve.

Knife gate valves are designed to work in some of the most harsh environments typically having a sharpened blade to cut through heavy liquids. Here is a list of symbols for various types of valves used in process industry. The benefits of knife gates also include that they are easy to actuate and cheap to produce. They are especially useful in wastewater applications where corrosion is an important issue.

Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere. So in addition to the valve design optimised for slurry media it is beneficial to have a knife made of acid.
