What Is Plumbing Valve?

Types of Valves in Plumbing

• Gate valve
• Globe valve
• Check the valve
• Plug valve
• Ball valve
• Butterfly valve
• Needle valve
• Pinch valve
• Pressure relief valve

1. Gate Valve

Types of Gate Valve

• Types of Gate Valve Based on Disk
  • Solid Taper Wedge
  • Flexible Wedge
  • Parallel Disk Valve or Split Wedge
• Type of Gate Valve Based on Body, Bonnet Connection:
  • Gate Valve: Screwed Bonnet Type
  • Gate Valve: Welded Bonnet
  • Gate Valve: Bolted Bonnet
  • Gate Valve: Pressure Seal Bonnet
• Types of Gate Valve Based on Stem Movement
  • Gate Valve: Os & Y Type Which Is Outside Stem and Screwed Type
  • Gate Valve: Non-Rising Stem Type

1.1. Gate Valve Based on Disk

1.1.1. Solid Wedge Gate Valve

1.1.2. Flexible Wedge Gate Valve

1.1.3. Parallel Disk Gate Valve or Split Wedge

1.2. Gate Valve Based on Body, Bonnet Connection

1.2.1. Gate Valve: Screwed Bonnet:

• It is used for inexpensive works and it is easy to design.

1.2.2. Gate Valve: Bolted Bonnet:

• It is one of the best designs and it is used in a maximum number of gate valves. It requires a seal at the joint.

1.2.3. Gate Valve: Welded Bonnet:

• It is one of the popular designs and it is lighter than bolted bonnet connection.

1.2.4. Gate Valve: Pressure-sealed Bonnet:

• This is very much useful for high pressure & high temperature. If the pressure of the body is greater then a greater force on the gasket will be there.

1.3. Gate Valve based on Stem Movement:

1.3.1. Gate Valve: OS and Y Gate Valve:

• It is a mounting stem valve and it starts the action by moving upward or downward movement. This type of valve totally controls by a hand wheel.

1.3.2. Gate Valve: Non-Stem Gate valve or External Gate valve:

• In this type of valve, there is no upward movement and a threaded portion is inside the valve. Here, no corrosion is observed and it is well known as Insider Screw Valve.

Gate Valve Applications:

1. Gate valves are generally used for all types of fluids like air, fuel gas, water, lubricating oil, drinking water, hydrocarbons, etc.
2. Sometimes gate valves are also used for transferring power and slurry.

Advantages of Gate Valve

• The main advantage of the gate valve is it's bilateral.
• The pressure drop in this system is very low.
• It is workable for high pressure and temperature.

Disadvantages of Gate Valve:

• The gate valve can not control the flow of the liquid.
• The operation time of the gate valve is very slow because it takes too much time to start the action.
• At the time of a partially open valve, it produces noise and vibration.
• Maintenance of this valve is very much difficult because it has only limited access.

2. Globe Valve:

2.1 Type of Globe Valve

• Z-type Globe Valve:
• Y-type Globe Valve:
• Angle-type Globe Valve:

2.1.1. Z-type Globe Valve:

2.1.2. Y-type Globe Valve:

2.1.3. Angle-type Globe Valve:

2.2. Globe Valve Types Based on Body Bonnet Connection:

2.2.1. Globe Valve: Screwed Bonnet

2.2.2. Globe Valve: Bolted Bonnet

2.2.3. Globe Valve: Welded Bonnet

2.2.4. Globe Valve: Pressure-sealed Bonnet

Application of Globe Valve:

1. This valve is generally used in high-point vents or low-point drums.
2. This type of valve is used in those places pressure drop is not a problem like feeding water, lubricating oil, chemical, air, etc.
3. This valve can be also automatic but in that case, the valve should be smooth instead of threaded.

Advantages of Globe Valve:

1. It has a better capacity to close the liquid.
2. The repair works are easy because it is accessible from the top.
3. It can be operated automatically.

Disadvantages of Globe Valve:

1. A huge amount of head loss will be there if there are two or more right-angle bends.
2. Obstructions and the discontinuity of the flow path can create a major amount of head loss.
3. In a high-pressure line, there is a major chance of internal damage.
4. When the valve is large then it requires power and it also creates noise.
5. It is costlier and heavier than any other valve of the same rating.

• Side Entry or Split Body type
• Three Piece Body type

5.1. Trunnion Mounted Ball Valve

5.2. Floating Ball Type

• In this type of valve system, two elastomeric systems.
• The stem of the ball is attached at the top of the slot and it allows the ball to start the quarter turn.
• A shaft is used to give access to lateral movement.
• This type of valve is difficult to control when the upstream pressure is too high.

5.3. Three-Way Ball Valve

• One inlet and two outlet
• An inlet and an outlet changing a flow
• Straight pass fluid  without inlet

Types of Valves in Piping

1. Ball Valve: The most common valve used for fluid flow, the ball valve, consists of a sphere with a hollow round hole in the center of the pipeline.
2. Gate Valve: Think of a gate valve (also known as a guillotine valve) like a medieval castle gate that moves straight up and down using a flat face, vertical disc or gate.
3. Check Valve: Most industrial facilities install check valves as a result of the hazard review process, as it allows fluid to flow through it in only one direction.
4. Butterfly Valve: Unlike some other valves, butterfly valves can limit or regulate the flow without completely restricting it. In a butterfly valve, a disk rotates clockwise or counter-clockwise to permit or restrict the flow (similar to the ball valve).
5. Diaphragm Valve: In this valve, a diaphragm lowers and raises to restrict or permit flow. These are excellent when the fluid being moved contains suspended solids.
6. Other types of valves may be used for applications other than those listed above. Most materials work with a variety of valves, and plants use them differently depending on their own experience.

What Are the Different Types of Valves and Their Uses?

1. Isolation Valves: Ball, butterfly, diaphragm, gate, pinch, piston, and plug valves.
2. Regulation Valves: Ball, butterfly, diaphragm, globe, needle, pinch, and plug valves.
3. Safety Relief Valves: Pressure release and vacuum relief valves.
4. Non-Return Valves: Swing check and lift check valves.
5. Special Purpose Valves: Multi-port, float, foot, knife gate, and line blind valves.
