First, the Selection and Setting of the Valve:

(1) The valves used on the water supply pipeline are generally selected according to the following principles:

1. When the pipe diameter is not more than 50mm, it is appropriate to use the globe valve. For pipe diameters over 50mm, gate valves and butterfly valves are preferred.

2. To adjust the flow or water pressure, regulating valves or stop valves should be used.

3. Areas requiring small water flow resistance (such as water pump suction pipes) should use gate valves.

4. For bidirectional water flow, gate valves and butterfly valves are recommended, while stop valves should be avoided.

5. Butterfly and ball valves are ideal for parts with limited installation space.

6. For sections frequently opened and closed, stop valves are suitable.

7. Multi-function valves should be used for large diameter water pumps.

Second: Valves in the Water Supply Pipeline:

1. At the junction of the municipal water supply pipeline to the residential area.

2. Nodes of the outdoor ring pipe network should have segmented valves based on separation requirements, especially if the pipe section is long.

3. Branch pipes from the main water supply or household pipes within residential areas.

4. Household pipes, water meters, and branch risers (bottom, vertical ring, upper and lower ends).

5. Main pipes of the ring network and connecting branch pipe networks.

6. Indoor pipes leading to households, public toilets, etc., with three or more distribution points on water distribution branches.

7. Water pump outlets and suction pipes of self-filling pumps.

8. Water tank inlets, outlet pipes, and drainage pipes.

9. Equipment water supply pipes (e.g., heaters, cooling towers).

10. Sanitary appliance distribution pipes (e.g., urinals, wash basins, showers).

11. Accessories such as automatic exhaust valves, pressure relief valves, water hammer eliminators, pressure gauges, sprinkler hydrants, and backflow preventers.

12. The lowest part of the water supply network should have a drain valve.

Third: Selection of Check Valves:

1. For low water pressure before the valve, swing, ball, and shuttle check valves are suitable.

2. For strict sealing after closing, choose a check valve with a closing spring.

3. For reduced water hammer, use quick-closing silencing check valves or slow-closing check valves with damping devices.

4. The valve break or spool of the check valve should be capable of closing automatically under gravity or spring force.

Fourth: Installation of Check Valves:

Check valves should be installed in the following sections of the water supply pipeline:

1. Lead-in pipes.

2. Inlet pipes of sealed water heaters or equipment.

3. Pump outlet pipes.

4. Inlet and outlet water pipes in tanks, water towers, and highland pools.

Note: Sections with pipe backflow preventers do not require additional check valves.

Fifth: Exhaust Devices in the Water Supply Pipeline:

1. For intermittently used water supply networks, place automatic exhaust valves at the network end and highest points.

2. In sections with air accumulation, install automatic exhaust valves or manual valves at peak points.

3. For pneumatic water supply devices with automatic air supply tanks, ensure automatic exhaust valves are at the highest point of the water distribution network.

Types of Industrial Valves - Applications, Advantages, and Disadvantages

Global industrial valves market is expected to surpass $77 billion by 2022, according to ‘Global Industrial Valves Market by Product Type, By Application, By Region, Competition Forecast & Opportunities, 2012 – 2022’. In the coming years, the demand for industrial valves is anticipated to rise due to their use in various commercial construction projects, automation projects, and ongoing industrialization. The expansion of existing facilities and technological innovations are fueling industry growth.

Industrial Valves Insights:

Industrial valves come in various types, including Gate Valves, Globe Valves, Ball Valves, Butterfly Valves, Check Valves, Pressure Valves, and Diaphragm Valves. Each valve performs distinct functions based on different working principles.

Ball Valves, which accounted for over 19% of the revenue share in 2014, are often used for flow control and tight shut-off applications.

Recently, butterfly valves have seen huge demand, especially in automation and oil & gas industries.

Check valves are projected to experience significant growth, with a CAGR of over 7% in the coming years. These unidirectional valves prevent process flow from returning to the system, thereby protecting equipment and preventing process disruptions.

Types of Industrial Valves - Applications, Advantages, and Disadvantages

Industrial valves regulate liquids, gases, and slurries by controlling the flow through pipes and other passageways via opening, closing, or partially obstructing them.

Different Types of Industrial Valves Include:

• Gate Valves
• Globe Valves
• Ball Valves
• Butterfly Valves
• Check Valves

1. Gate Valves

Gate Valves are designed to act as isolation valves and control the flow through pipes. These valves, commonly seen in homes and commercial centers, are made from materials like stainless steel, cast iron, alloy steel, and forged steel.

Advantages

• Very low friction loss
• Can be used bidirectionally
• Provide laminar flow with minimal pressure loss
• Help save energy and reduce ownership costs
• Low pressure drop and tight sealing when fully open

Disadvantages

• Cannot be opened and closed quickly
• Can cause vibrations
• Leakages may occur under irregular high-temperature changes
• Complex operation, maintenance, and repair of seating surfaces

Applications:

• Suitable for high temperature and pressure conditions
• Used for on-off applications

2. Globe Valves

Globe Valves are among the most popular valves used in various applications. These valves, similar to gate valves, use linear motion to throttle flow and control it in pipelines by positioning a movable disk or plug in relation to the stationary ring seat.

Advantages

• Good throttling and full-closing characteristics
• Short opening-closing time
• Easier body ring seating surface process
• Can be used as stop-check valves
• Contain positive shut-off

Disadvantages

• Higher pressure loss
• Require larger force or high-torque actuators to close under high pressure

Applications:

Globe valves are primarily used for throttling purposes and suitable for high-temperature applications.

3. Ball Valves

Ball Valves use a ball to control the flow. These valves are ideal for gases as they offer better sealing and support pressures up to 700 bars and temperatures up to 200°C. They are easy to operate and repair with simple structures.

Advantages

• Compact, low-maintenance design requiring no lubrication
• Cost-effective
• Provide leak-proof service
• Quick opening and closing
• Offer multi-way design flexibility

Disadvantages

• Not suitable for permanent throttling
• Residual fluid particles can cause leakage and other problems

Applications:

• Used for flow and pressure control and shut-off for corrosive fluids, slurries, normal liquids, and gases
• Common in the oil and natural gas industry, manufacturing sectors, chemical storage, and residential uses

4. Butterfly Valves

Butterfly Valves regulate flow but with limited control capacity. Operated by rotating a handle 90 degrees, these valves are used in water supply, wastewater treatment, fire protection, gas supply, chemical and oil industries, etc. They can be operated manually, electronically, or pneumatically.

Advantages

• Very accurate, advantageous in industrial applications
• Reliable and require minimal maintenance
• Throttling capability
• Easy installation and removal without pipe system dislocation

Disadvantages

• No tight shut-offs
• Portion of the disc always in the flow, causing pressure drop

Applications:

• Pharmaceutical, chemical, and food processing services
• Corrosive liquids at low temp and pressure

5. Check Valves

Check Valves, also known as Non-Return Valves (NRV), allow liquid flow in one direction only, preventing backflow. They protect pumps in liquid applications and compressors in gas systems. These valves operate automatically based on fluid flow velocity.

Advantages

• Prevent backflow
• Sustain pressure
• Serve as a backup system

Disadvantages

• Not suitable for pulsating systems
• Closing elements may cause damage and excessive wear

Applications:

• Used in various markets and applications with versatile material options
• Prevent backflow and maintain pressure
• Common in refining, petrochemical, chemical industries, wastewater management, and manufacturing

Industrial valves can be bought at affordable prices from global manufacturers.
