What is Gate Valve?

A gate valve can be defined as a type of valve that used a gate or wedge type disk and the disk moves perpendicular to flow to start or stop the fluid flow in piping.

A gate valve is the most common type of valve used in any process plant. It is a linear motion valve used to start or stop fluid flow. In service, these valves are either in a fully open or fully closed position.

When the gate valve is fully open, the disk of a gate valve is completely removed from the flow. Therefore virtually no resistance to flow. Due to this very little pressure drops when fluid passes through a gate valve.

To achieve proper sealing, when the valve is fully closed, 360° surface contact is required between disk and seats.

Gate valves should not be used for regulation or throttling of flow because accurate control is not possible.

The high velocity of the flow in the partially open valve may cause erosion of the disc and seating surfaces and also creates vibration and noise.

Types of Gate Valves

There are three ways to classify the gate valve.

Types of Disk
1. Solid taper wedge
2. Flexible wedge
3. Split wedge or Parallel disks Valve
Types of Body Bonnet Joint
1. Screwed Bonnet
2. Bolted-Bonnet
3. Welded-Bonnet
4. Pressure-Seal Bonnet
Types of Stem movement
1. Rising Stem or OS & Y Type (Outside Stem and Screw Type)
2. Non-rising Stem type

Features:

● Flat-bottomed seat traditional gate valves are usually deposited in the bottom groove of the valve due to external objects

such as stone, wood, cement, paper, debris, etc., after flushing the pipe with water. Cause cannot close tightly and form slack

phenomenon, soft-sealing gate valve using the same as the pipe at the bottom of the flat design, not easy to cause debris deposition,

the fluid flow unimpeded, the whole package glue valve plate is made of high quality rubber, within the whole outsourcing, domestic

first-class rubber vulcanization technology make the valve plate after vulcanization can ensure accurate geometry size, and rubber

and nodular cast iron gate connecting firm, not easy to fall off and elastic memory preferred.

● The corrosion resistant valve body is painted with powder and epoxy resin to prevent corrosion and rust of the valve body, and can

be used in sewage system.

● Not easily broken into traditional cast iron.
