Threaded Ball Valve with Top Mounted

Threaded Ball Valve with Top Mounted

Threaded ball valve with top mountedOverview：

Threaded ball valve with top mounted integral body design top mounted pivot fixed support, flange structure integral pivot fixed ball stem design double blockage relief function high strength integral ball stem structure. Ensures precise positioning of the ball pivot with anti-blow-out protection structure 2 sets of O-ring seals, plus fireproof packing structure on the stem.Effectively prevent leaks anti-corrosion, low coefficient of friction bearings due to nickel corrugated springs make the nylon seal metal seat to the ball movement. With inlet and outlet bi-directional sealing function superior performance of standard nylon and PEEK seats to ensure effective sealant dweller design in low-pressure conditions, in emergency conditions can be dwelling sealant to the stem or seat for sealing using a unique seat retractable technology. The ball stem is replaceable online. Stem seal ring metal seat and corrugated spring torque is reduced to a minimum to facilitate the operation of electric valves ball stem and valve body effective contact, superior performance anti-static grounding equipment pre-set drive device platform and screw holes, ready to assemble the drive device fire function; when the valve seat is burned or damaged, the metal seat automatically tighten the ball, the seat and the ball between the smaller leakage.

Threaded ball valve with top mounted Features：

1. the valve body as a whole top mounted threaded design structure: the valve body as a whole top mounted structure than the usual valve body pipeline strength, structural improvements and technical changes to adapt to the requirements of earthquake resistance, in the work of the device system pressure relief, the valve can be online inspection and maintenance, so that device maintenance simplicity, maintenance only need to open the valve cover lifting out the ball and support body without having to remove the entire valve from the pipeline. This eliminates many aspects of pre-emptive work before use or repair and does not result in wasted energy, making maintenance more convenient. In specific occasions, the top-mounted fixed ball valve can not affect the normal operation of the pipeline system during repair, as long as the ball and seat assembly can be removed and the valve cover can be quickly sealed to immediately resume the operation of the pipeline system under pressure, so that the benefits of repairing the valve caused by the loss to a lesser extent. Flange connection, easy to replace or disassemble the maintenance valve.

2. automatic pressure relief structure: in the cavity pressure appears abnormally high phenomenon, the valve cavity stagnant pressure abnormally exceeds the spring preload, the valve seat back from the ball, to achieve the effect of automatic pressure relief, after pressure relief valve seat automatically reset.
