Q61F/Y Q367Full Welded Ball Valve

1, all welded ball valves (full welded ball valve (Q61F / Y))
Product Description:
Valve body and by all welding of carbon increase the composition of Teflon seals can often operate with impurities and chemicals in the case of long operating life. Fine stainless steel grinding ball can guarantee many years of open and close with ease, reliable operation.
Using float structure, slope to ensure flexibility in the ball ring pressed on, even in the pressure instability, the valve can guarantee tight.
Anti-leak stem structure uses two "Q" ring, so that turning of the stem and sealed tight with ease.
Features:
Does not require maintenance, adjustment and lubrication, easy to install, low running costs in the next long-term reliable operation.
Stem can be lengthened, easy to heat.
Operating handle can be removed for the installation.
Valve body casting non-heavy and unreliable.
Install adjusting mechanism, very easy.
Second, Q367 series plus pole-type ball valve full welded Buried
The company's full welded ball valve is widely used in water directly buried, chemical, oil and natural gas buried pipeline, the longer the time interval between valve replacement overhaul, with its excellent quality by the majority of users.
All-welded underground ball valve structural features
In addition to the advantages of a common fixed ball, but also has the following characteristics:
1, all-welded construction, no leaks in the flange, and pipe with welded or flanged connections. The former is not flanged pipe and valve leakage, which facilitate the demolition of the maintenance valve.
2, valve seat sealing surface material can be selected according to different use of media PTFE, nylon, steel, carbide, etc., can adapt to different large range of temperature, pressure and corrosion requirements.
3, the stem can be extended according to user specific installations for the ground operation.
4, compared with those of the conventional ball valve is small, light weight, beautiful appearance, durable and so on.
