Top mounted pneumatic ball valve design standards and characteristics

top mounted pneumatic ball valve is widely used in the oil and gas pipeline, and oil production, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food and paper and other devices. Remove simple jacket type pneumatic valve in the pipeline ball fast, convenient and quick maintenance. When pneumatic valves on the pipeline failure needs to be repaired, don't need to remove the pneumatic valve from the line, just pull down the flange bolts and nuts, the pneumatic valve cover and pneumatic valve rod assembly from the aerodynamic body together, then take out the ball and pneumatic seat assembly. Online repair sphere and pneumatic seat. This saves time of maintenance, will produce to minimize the loss.

characteristics of top mounted pneumatic ball valve
mount type fixed pivot support integral aerodynamic body design, flange structure monolithic pivot fixation cue design the function of blocking the discharge high-strength integral structure of the cue.
to ensure the precise positioning of pivot sphere structure of blow-out proof protection group type O sealing ring, and a pneumatic valve stem fireproof packing structure.
effectively prevent leakage corrosion resistance, low coefficient of friction in the bearings because of ripple spring nylon seal can be nickel metal pneumatic seat to move the ball.
with functions of import and export of two-way sealing performance superior standard nylon and PEEK pneumatic seat, ensure the effective sealing sealants to live under a state of low pressure into the design, can live into the sealant under a state of emergency, the air valve stem or pneumatic seat sealing adopt unique pneumatic valve seat can retract technology.
online replaceable cue. Pneumatic valve stem seal metal pneumatic spring seat and ripple torque is reduced to minimum, is advantageous for the pneumatic valve operation, the club and pneumatic valve body effective contact superior performance of static equipment preset drive platform and screw hole, at any time, can assemble drive fire prevention function; When the pneumatic seat burn out or damaged, the metal pneumatic seat automatically tiejin sphere, pneumatic seat and small leakage between spheres.
