Q:What does "S" mean by ball valve Q11S?
S stands for plastic sealing.Stainless steel ball valves only need to rotate 90 degrees of operation and small rotating torque can be closed tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel.The main features of the valve itself is compact, easy operation and maintenance, stainless steel ball valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow.Ball valve body can be integrated, or can be combination.This kind of valve should be installed horizontally in the pipeline.Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve.Stainless steel ball valve is divided into 304316321 stainless steel ball valve.
Q:What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
Features of pneumatic angle seat valve:1 、 visual position indication: it can be connected with limit switch or emergency manual device.2 、 easy to install: pneumatic head can rotate 360 degrees. One or two limit switches can be easily installed.3 、 advanced pneumatic controller: thickened engineering plastic shell, safe and reliable. Low wear piston structure with large capacity and low consumption. Self lubrication of internal components, maintenance free.4, with a variety of control methods: normally open, normally closed, double action.5. Require smaller pneumatic actuators: when the fluid flows over the stem, a smaller control head is optional.6, easy to connect: MAMUR standard connection, embedded metal connector.7, long-life Guide: Lease stem shaped Teflon (PTEE) sealed to avoid the import of stolen goods. Self lubrication, maintenance free. The stem is specially treated to ensure optimum fixation and automatically correct position.8. Without water hammer, the water hammer (water shock force) is absorbed when the fluid flows into the bottom of the valve stem.9, advanced valve body: flow is larger than ordinary angle block 30%, smaller size, better fluid flow pattern. 316 stainless steel body, Teflon seals, high temperature resistance, corrosion resistance. Life as high as seven million times
Q:1 piece, 2 piece, 3 piece ball valve, which places are used in large quantities?
Three piece ball valve has the following advantages:1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Q:A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve
Four is 1/2=DN15, 21mm data is not accurate, if it is metric thread, provide tooth pitch and thread diameter.
Q:What does "ball pq340h-10c-1200" mean?
This is the worm gear eccentric hard seal hemisphere valve, 10 kilograms of pressure, caliber is 1200.
Q:What do you mean by ball valves dn20pn1.6rf?
DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve
Q:PP-R double joint hot melt copper ball valve DN50 connection method how to connect?
The way of hot melt welding, using special electric welding machine can do the things that do, configuration 50
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 diameter
Q:Principle of forced sealing ball valve
With spring to achieve forced sealing, not applicable to high pressure
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
