Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipeline, its strength, safety, resistance to harsh environments such as in the design of a special consideration, applicable to all kinds of corrosive and non corrosive media. It compared with the floating ball work force, fluid pressure before the valve resulting in the ball on all transferred to the bearing, not to move the ball to the seat, the seat would not put too much pressure, so the torque of the fixed ball valve, valve seat seal small deformation, stable performance, long service life, suitable for high voltage and large caliber situation. Advanced spring pre - seat assembly, with self - tightening characteristics, to achieve the upper seal. Each valve has two seats, each direction can be sealed, so the installation does not flow to the limit, is a two-way. General level installation of this valve.
Fixed ball valve has two type and three type two body structure, the flange bolts, sealed with PTFE inserts into the stainless steel ring, steel ring is arranged at the rear part of the spring to ensure the seat close to the ball, keep the seal. The upper and lower stem are provided with PTFE bearings, reducing friction, the operation is saved, the bottom of the small shaft is provided with an adjusting sheet to ensure the position of the ball and the sealing ring. Full bore valve flow aperture consistent with the pipeline diameter for pipeline cleaning.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
All kinds of pipe fixed ball valve suitable for Class150~Class1500, PN16~PN100, JIS 10K~JIS 20K, suitable temperature: -196~350 degrees, used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, widely used in petroleum refining long distance pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, steel etc.. The driving mode of the fixed ball valve is worm wheel and worm drive, manual, pneumatic or electric. Fixed ball valve with flange, butt welding can also be adopted.
