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: Replacement method of PPR hot melt ball valve: The above problems belong to the wire type, and the name is: double live catch valve, directly loosen the lock nut, replace the valve can be.When the valve is purchased, the merchant sells a full valve. When the change is made, both ends of the live joint lock nut are removed and the valve is directly connected with the original lock nut on the pipe.

Q: DN20 copper ball valve with large PPR converter connector: See how big your tube is. 20 tubes are straight with 20*1/2 internal teeth, and 25 tubes are straight with 25*1/2 internal teeth

Q: What does "DN25 Q41F46-16C" mean?: DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of general diameter of 25 mm

Q: What does W represent in copper ball valve Q11W-16T?: According to the provisions of the JB/T 308-2004 valve type programming method:Q== ball valve1== connection: internal thread1== ball valve structure: straight through flowW== sealing surface material: body. That is, the sealing material is the same as the body material-16== pressure rating: 1.6MPaT== body material: copper or copper alloy

Q: Are ball valves and float valves a thing? If not, what valves belong to the valve, screw valve, threaded flange valve, welding flange valve or flange valve?.Online, etc.. Thank you: The answer upstairs is more accurate, I will add.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. float valve, that is upstairs to explain the kind of specific, you can refer to the toilet, which is used on the water supply device is this structure.The 3 threaded valve, threaded flange valve, valve flange welding flange or valve: This refers to the connection forms of body, such as your home with the water valve between the valve and pipeline is usually a threaded connection, then the other is threaded, welding, flange connection means.

Q: For the master enlighten Q47 ball seat spring hole number is determined by how: Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameterCalculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).

Q: Switch valve type, switch valve, ball valve or butterfly valve is good: Ball valve and butterfly valveBall valve is used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.

Q: Difference between fireproof and antistatic ball valve and ordinary ball valve: Ha ha, that is, non sparking metal, alloy, copper, alloy, aluminum is all right

Q: What are the applicable conditions of ball valves?: This deformation can compensate the ball manufacturing accuracy and surface roughness, and ensure the sealing performance of the ball valve.Because the valve seat ring is usually made of plastic, so the choice of valve structure and performance, to consider the ball of fire and fire, especially in petroleum, chemical, metallurgy and other departments, the use of ball valve in the equipment and piping system of flammable and explosive medium, should pay attention to fire and fire.Usually, the double adjustment, strict sealing, slurry wear necking channel, the rapid opening and closing movement (1/4 turn open and close), high pressure cut-off (pressure difference), low noise, there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere,It is recommended that ball valves be used in piping systems with small operating torque and low fluid resistance.

Q: What does copper ball valve mean by "1/2"?: 1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.
