Reliable seat seal
The structure design of elastic sealing ring has been adopted for floating ball valves. This seat design features a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower, where the contacting area is smaller. Thus, the reliable seal is ensured. When the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to undertake the bigger force 5 pushed by the medium without any damage.
Fire safe design
With the valve heated in a fire application, the non-metal material parts such as seat sealing ring of PTFE, stem back seat gasket, gland packing, and the sealing gasket between body and bonnet might disintegrate or be damaged due to high temperature. Specially designed structure of auxiliary metal to metal seal is provided to effectively prevent both internal and external leakage of the valve. As required by customers, floating ball valves with fire safe design can meet the requirement of API 607, API 6FA, BS6755 and B/T 6899
Reliable stem seal
The blow-out proof design has been adopted for the stem to ensure that even if the pressure in the body cavity is risen accidently and the packing flange becomes invalid, the stem may not be blown out by medium. The stem features the design with a backseat, being assembled from underneath. The sealing force against the backseat gets higher as the medium pressure becomes higher. So the reliable seal of the stem can be assured under variable medium pressure
Anti-static feature
The traditional packing flange design has been improved to be of two piece structure, i.e., being as a packing flange plate and a follower, the latter contacts the flange plate with spherical surface. Thus, the follower remains vertical always, and is lined internally with a PTFE bush to prevent the galling against and friction between the stem, which can also reduce the operation torque of the valve.

- Q:The difference between ball valve Q341F and Q347F
- 7: fixed ball valve, F: fluorine plastic valve seat sealStructural distinction:Floating ball: ball valve is floating, in the media under pressure, that the ball can produce a certain displacement, and tight at the outlet end of the sealing ring, to ensure that the export side seal, a single side forced seal.Fixed ball: the ball of the ball valve is fixed, the pressure does not produce movement, therefore, in the design, two sealing ring should be sufficient pre tightening force to ensure sealing, double sided forced seal.
- Q:Stainless steel ball valve Q41F-16P DN80 weight is
- The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers
- Q:Is a plastic ball valve, connecting France is hot melt.
- Visible, electric ball valve in daily life, industrial manufacturing and other fields have great application and market space. With the development of the times, the electric valve also put forward higher requirements, such as digital remote control, so the development of this industry, cannot do without the progress of technology, from the past to the ordinary valve electric valve electric valve to now, by the digital intelligent valve, look first to the application of new technology on the product rapidly the transformation and development of new products to meet market demand.

- Q:I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......
- First, the advantages and disadvantages of the ball valve1, advantages:Minimum flow resistance (actual 0);Because it is not stuck at work (without lubricant), it can be reliably applied to corrosive media and low boiling liquid;Complete sealing can be achieved in larger pressure and temperature range;It can realize quick opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so that it can be used in the automation system of the test stand. Quick opening and closing valve, operation without shock;The spherical closure can be automatically positioned at the boundary position;The working medium in the two-sided reliable seal;In the fully open and fully closed, the ball and seat sealing surface and the dielectric isolation, the high-speed media through the valve sealing surface will not cause erosion;It has the advantages of compact structure, light weight, it could be considered for most reasonable structure of the valve system of medium low temperature;To body symmetry, especially the welded body structure, can well withstand the stress from the pipe;The closure of parts can withstand the pressure differential.11;They all welded ball valve can be buried underground, so that the valve parts from erosion, the maximum life of up to 30 years, is the most ideal oil and natural gas pipeline valve.
