American standard worm gear stainless steel ball valve Q341F

Date:[2016-10-20]    hits: American standard worm gear stainless steel ball valve Q341F

Q347F manual turbine-fixed ball valve is a new generation of high-performance ball valve for long-distance pipelines and general industrial pipeline, its strength, safety, resistance to harsh environments in the design of a special consideration. Fixed ball valve for a variety of corrosive and non-corrosive media. Fixed ball valve and floating ball valve compared to work, the valve before the fluid pressure on the sphere of the force generated all passed to the bearing, will not move the ball to the valve seat, so the seat will not be too much pressure, so fixed Type ball valve torque, valve seat deformation is small, stable sealing performance, long life, suitable for high-pressure, large-caliber occasions.

Advanced spring pre-seat assembly with self-tightening feature for upstream sealing. Each valve has two seats, each direction can be sealed, so there is no flow limit installed, is two-way. Fixed ball valves are generally horizontally mounted.


Second, Q347F manual turbine fixed ball valve works:

   Q347F manual turbine fixed ball valve is a new generation of high-performance ball valve for long-distance pipelines and general industrial pipeline, its strength, security, resistance to harsh environmental design considerations, suitable for a variety of corrosive and non- Corrosive medium. It is compared with the floating ball valve, work, the valve before the fluid pressure generated in the sphere of all the forces transmitted to the bearing, will not move the ball to the seat, so the valve seat will not be too much pressure, so fixed ball Of the torque is small, small deformation of the valve seat, sealing performance and stability, long life, suitable for high-pressure, large-caliber occasions. Advanced spring pre-seat assembly with self-tightening feature for upstream sealing. Each valve has two seats, each direction can be sealed, so the installation does not flow restrictions, is two-way. The valve has two blocks and three blocks of two kinds of valve body structure, the flange with bolted, sealed with PTFE reinforced stainless steel ring embedded, there is no spring steel ring to ensure that the seat close to the ball, to maintain seal. The upper and lower stem are not PTFE bearings, reducing wear and tear, operation effort, there is no adjustment of small shaft at the bottom of the ball, to ensure that the ball and the ring at the location. Full Diameter: The valve flow aperture is the same as the inner diameter of the pipeline to allow the line to be cleaned. Applicable medium: water, gas, oil, natural gas and acid-base corrosive media.


Third, Q347F manual turbine fixed ball valve Features:

  1, long service life, the choice of self-lubricating PTFE ring seal material. Ball and seal ring micro-wear, effectively improve the service life;

  2, small size, light weight, easy to install and maintain;

  3, fixed ball valve structure can be installed in any direction and any part of the pipeline;

  4, V-type then stacked axial packing, to achieve anti-corrosion A-level seal.


Fifth, Q347F manual turbine fixed ball valve main parts Material:
