Q41N stainless steel forged steel high pressure ball valve

Q41N high-pressure forged steel balls and Q61N forged steel high-pressure ball valves are mainly used for long-distance pipeline transportation of oil and natural gas and city gas pipeline systems. Due to the unique characteristics of the long-distance pipeline valve, its ability to withstand pipeline stress, as well as safety, weather resistance, and long-term use of reliable sealing design structure have been fully considered in the design. The driving mode can be manual, worm gear, pneumatic, electric, the connection mode can be flange, welding, the structure is three-stage, the sealing structure can be soft seal, hard seal, pressure range PN1.0-32.0Mpa, nominal diameter It is DN10-200mm, and the material can be forged steel or forged stainless steel. Due to the wide range of use of valves, the same valve has different collocations in different occasions and working conditions. The high-pressure forged steel ball valve is a valve that uses a sphere with a circular channel as the opening and closing part. The sphere rotates with the stem to realize the opening and closing action. The valve is closed when it rotates 1/4 turn (90°) in the positive direction. When reverse rotation 1/4 turn (90°), the valve opens. . The opening and closing part of the ball valve is a holed sphere, which rotates around the axis perpendicular to the passage, so as to achieve the purpose of opening and closing the passage. Ball valves are mainly used to open and close pipelines and equipment media.

Features

1. All parts are forgings

2. The bottom-mounted valve stem is adopted, and the equipment is inverted and sealed.

3. The inlaid valve seat is adopted, and the O-ring is installed behind the valve seat to ensure that the medium does not leak

4. The sealing surface is made of nylon or polytetrafluoroethylene, and its friction coefficient is usually 1/3 of Babbitt alloy, so it is a natural slippery material. But the bending strength, impact strength and high ductility are on par with metals.
