Types of Valve

The valves produced by our company mainly include the following types:

Ball Valve

Ball valve is a type of quarter-turn valve that controls flow through a pipe using a hollow, perforated ball.

Valve Actuator

Valve actuator is a device that automatically opens or closes a valve, often using an external energy source like electricity, compressed air, or hydraulic pressure.

Core Functions of Valve

Isolation: Start or stop fluid flow within a system (e.g., ball, gate valves).

Regulation: Throttle flow to control rate, pressure, or direction (e.g., globe, butterfly valves).

Non-return: Prevent backflow or reverse flow in pipelines (e.g., check valves).

Mixing/Diverting: Blend or reroute fluid paths (e.g., multi-port ball valves).

Applications of Valve

Power industry
Many power plants generate electric power in steam plants that use fossil-fuel and high-speed turbines. Gate valves are the top choice for power plant on/off applications. Although other valves like the Y-pattern globe valves are sometimes used.

Water works
Water distribution requires relatively low-pressure levels and ambient temperatures. For this reason, different valve design elements that wouldn’t be found somewhere like a power plant, can be used for water works.

Offshore industry

Offshore production facilities and oil rigs have piping systems which contain a plethora of valves. These are built to a variety of specifications in order to handle all the flow control challenges.

Wastewater

Wastewater lines collect all the waste solids and fluids and direct them to the sewage treatment plant. Treatment plants feature low pressure piping and valves to carry out their work, and in many cases, the requirements for wastewater valves are much more lenient than the clean water requirements.

Oil and gas production

Gas and oil wells and their production facilities use many heavy-duty valves. Oil gushing hundreds of feet in the air are no longer like to occur, it does illustrate well the pressure of underground gas and oil.

Valve Installation Steps

Preparation
Before installation, ensure that the valve specifications match the system requirements. Clean the valve components thoroughly and check for any damage or defects. This includes checking the sealing surfaces and ensuring there are no obstructions.

Pipe Cleaning
Clean the pipelines and equipment to remove oil, welding slag, and other debris. This prevents damage to the valve sealing surfaces and ensures smooth operation.

Handling
For valves larger than DN100mm, use lifting tools to handle the valves. Secure the ropes to the flange or bracket, not the stem or handwheel, to prevent damage. Lift and place the valves gently to avoid any impact or stress on the valve components.

Alignment and Welding

Align the valve flange with the pipeline flange carefully to avoid misalignment. Use appropriate gaskets and tighten bolts symmetrically to ensure a proper seal. For threaded valves, use suitable sealing materials like PTFE tape or sealant to prevent leaks.

Post-Welding
Inspect the welds thoroughly and conduct X-ray inspections for critical valves if necessary. After welding, flush the pipeline and valve to remove any remaining debris. This step is crucial to ensure the system is clean and ready for operation.

Final Checks
Perform a final check on the valve and pipeline system to ensure everything is installed correctly and functioning properly. This includes checking for leaks, verifying the flow direction, and ensuring all connections are secure.

FAQ

Q: What height should valve be installed at?

A: Valve handles should be about 1.2 meters above the ground for easy access. If they are higher, use platforms or extensions for frequent operations.

Q: How should valves on horizontal pipes be oriented?

A: Valve stems should point upwards to avoid corrosion and ease of operation. Downward stems are inconvenient and can cause maintenance issues.

Q: What should be done if a valve is installed over 1.8 meters high?

A: Use chain wheels, extension rods, platforms, or ladders for infrequent operation valves to ensure safe and easy access.

Q: How are flow directions determined if not marked on the valve?

A: Determine the flow direction based on the valve's structural principles and ensure it matches the intended flow of the system. Always refer to the product manual if available.

Q: What warranty do you provide for motorized valves?

A: We provide a standard 12–24 month warranty for our motorized valves, covering manufacturing defects.

Q: How should I choose the right size and type of motorized valve for my project?

A: You should consider pipe size, flow rate, working pressure, voltage, and application. Our engineering team can help you select the best motorized valve solution.
