Q41 forged steel ball valve

Q41 forged steel ball valve

Q41 forged steel high-pressure ball valve is mainly used for long-distance pipeline transportation of petroleum and natural gas, as well as urban gas pipeline systems. Due to the unique characteristics of valves used in long-distance pipelines, their ability to withstand pipeline stress, as well as safety, weather resistance, and long-term reliability, were fully considered in the design; Sealing and structural design are also operated by some enterprises. The operation methods include manual worm gear drive, pneumatic, electric, pneumatic/hydraulic linkage, electric/hydraulic linkage, and various special control forms.

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
