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:Ball valve Q41f and Q11f difference, whether universal?: Generic. The Q41F 4 stands for flanged connections, and the Q11F 1 represents the internally ribbed pipe

Q:Ask you engineer, 150mm diameter ball valve or butterfly valve, installed in the water supply pipe, water pressure 0.4Mpa, driven by the electric actuator, should much force distance?Sincere thanks, enthusiastic support of net friend.: Reference: ball valve 1000N on the line, butterfly 250N canThis valve with the switch torque is related, each manufacturer according to the workmanship, process switching torque is not the same.You can refer to the recommended value of the actuator manufacturer

Q:The difference between ball valve q41f46-16c and q41f46-16: C stands for carbon steelThe latter doesn't indicate material

Q:Home PPR pipe ball valve, which is good?: See what you use as a route. The main valve, then use the cut-off valve, because the cut-off valve is high, low, out of the valve. If the toilet or kitchen, often use the valve with the ball valve, because it is not bad, more suitable for regular switching use

Q:What are the differences and advantages between O ball valve and V ball valve?: 5, high reliability1, the ball and valve seat a pair of sealing pairs, there will be no abrasions, rapid friction and other failures;2, stem into the built-in type, to eliminate the stem under the action of fluid pressure may be caused by the packing gland release flying accident hidden trouble;3 、 adopt antistatic and fireproof structure ball valve, which can be used to transport petroleum, natural gas and gas pipelinesV type ball valve structure of a right angle turn, can achieve flow regulation, according to the V type angle V type sphere, realize different proportions, V type ball valve and valve actuator and positioner supporting the use, the ratio can be adjusted V type valve adjustment for a variety of occasions, with a rated flow coefficient large, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. For control of gas, steam and liquid medium.V type ball valve for rotary type rectangular structure by V type valve, pneumatic actuator, positioner and other accessories; there is a similar more than 100 of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors, the shear capacity of strong.

Q:What does telescopic ball valve mean? What does it mean?: An expansion valve is mostly for repair or replacement of the water meter behind the expansion is the activity space, for example for water when the water meter is just let it back so easily won, for good and put it out to tighten the gentry good handle table.

Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?: Since the flow direction of the medium through the valve has changed, so the minimum flow resistance of the cut-off valve is higher than most other types of valvesThe ball valve has the lowest flow resistance

Q:How many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Big 50, pleaseHow many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Beg you greatly! Don't forget the detailed form!: No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.

Q:What's the difference between T ball valve and L ball valve?: This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.

Q:Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?: Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
