Fully welded turbine ball valve


The Q361F-25C fully welded turbine ball valve is a high-performance valve widely used in various fields such as petroleum, natural gas, chemical industry, power generation, metallurgy, and shipbuilding.

Key words:

Full Bore Welded Ball Valve


The QA61F-25C full-bore welded ball valve is a type of ball valve that has a full-bore passage, meaning the internal passage diameter of the valve is the same as the diameter of the pipeline, which does not create fluid resistance or pressure drop.

Common types of electric butterfly valves.


The electric butterfly valve is what is commonly referred to as a drainage valve in daily life, and this type of valve is often found in many steam systems.

Considerations for Selecting Special Valves


Most fluid media used in the processing industry involve oil and gas flows with different levels of corrosiveness.

What materials are used for butterfly valves?


Gray cast iron is suitable for nominal pressure PN ≤ 1.0 MPa, with a temperature range of -10℃ to 200℃ for media such as water, steam, air, gas, and oil products.

The instrument for measuring professional filters is a photometer.


The testing steps for professional filters need to be mastered step by step and applied.

Teach you how to calculate the pressure loss of a Y-type filter


Y-type filters are an essential device on the medium transport pipeline, usually installed at the inlet of pressure reducing valves, pressure relief valves, constant water level valves, or other equipment.

Y-type filters are easy to clean and maintain.


Y-type filters are suitable for the purification and filtration of gas media (natural gas, artificial gas, liquefied petroleum gas, and other non-corrosive gases).
