Gate valve types

A Complete Range of Gate Valve s. Contact Our Company Today. What are different types of gate valves? What is the difference between gate valve and ball valve? How do you replace a gate valve?

Do ball valves seal better than gate valves? Types of Gate Valves Solid Wedge Gate Valve. Flexible Wedge Gate Valve. The flexible wedge is a one-piece solid disk with a cut around. Split wedge or Parallel disks Gate Valve.


Two basic types of gate valves are the manufactured-wedge type and the double-disc type , and there are several variations within each of these types. A third type of gate valve, called conduit valve, is shown in Fig.

The disc is free to adjust itself to the seating surface if one-half of the disc is slightly out of alignment due to some foreign matter lodged between the disc and the seat ring. Gate valves are usually divided into two types: parallel and wedge-shaped. The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream.


Shut-off is obtained by the free-floating seat or disk gate allow the upstream pressure to seal the seat and disk against any unwanted seat leakage. VALVE BY DESIGN GATE VALVE : This type is the most used in piping and pipeline applications. GLOBE VALVE : This type of valve is used to throttle (regulate) the fluid flow. CHECK VALVE : this type of valve is used to avoid backflow in the piping system or the pipeline. BALL VALVE : A Ball valve.


The body is generally connected to other equipment by means of flange screwed or welded connections. The bonnet , which containing the moving parts, is attached to the body, usually with bolts, to permit maintenance. At high pressures, friction can become a problem. As the gate is pushed against its guiding rail by the pressure of the medium, it becomes harder to operate the valve. Although these valves can be used for throttling – some include locking mechanisms on the handle to counteract the force of water on the disc – they are best utilized fully opened or closed.


Among the valve types , butterfly valves are compact, with relatively short bodies, making them significantly lighter than other types. Valves can be categorized into the following types , based on their operating mechanism.

Ideal for quick shut-off, since a 90° turn completely shuts-off, compared to multiple 360° turns for other manual valves. This valve is called a gate valve because it contains a closure element called a gate that stops flow. The gate acts like a shutter that separates the inside of a house from the outside or a door that separates two rooms. They are suitable for wastewater applications and neutral liquids.


Knife gate valves are used for slurries and powder media. Ball valves are perhaps the most reliable type of valve and are commonly used. Globe valves are used to regulate or throttle the flow. Detailed Explanation about a gate valve.


Valves are essential parts of any piping system used to control the flow and pressure of contents, whether that is oil, gas, liquid or vapors. A gate valve describes the mechanism by which the valve is opened and closed. To turn a gate valve on or off, a circular handle is turned to raise or lower a metal gate inside the valve body. When the valve is off, the gate blocks the flow of water. Resilient Wedge Gate Valves.
