Q:What's the meaning of the ball valve bore 14 "x 12"?
Should refer to imports 14 inches, export 12 inches, this kind needs to make to order, at present domestic possibly not yet.
Q:Allowable leakage on ball valves: what does CLassVI mean?
This is the valve leakage level, level VIThe GB/T4213-92 standard specifies six grades for the valve leakage. The specific requirements are shown in the standard table. The lowest level is level I, without specific requirements; the highest level is grade VI, i.e., the bubble grade.
Q:Is the ball valve switch in front of the water meter or after the water meter?
It's in front of the water meter. What's the problem?.
Q:What are the inside parts of the ball valve?
The universal ball valve includes the stem, valve ball, seat, seat seal and packing.
Q:About the characters on the ball valve (what do s and O mean?)
That's almost what it means. To be exact, S is SHUT and O is OPEN
Q:Is the ball valve ball valve?
Therefore, strictly speaking, eccentric hemisphere valve ball valve, butterfly valve is more like a ball valve.
Q:What do you mean by 266 in the 266 brass ball valve?
In order to consider the cost, some manufacturers put in different environment in accordance with the actual need in addition to the basic properties (such as gas safety requirements, key strength, air conditioning temperature, focus on material and penetration, ordinary water can have the basic properties, can economic production and product classification), but in the national standard of the same specifications or inside them the same type,
Q:What's the diameter of the 4 point ball valve?
"4 point ball" in the "4 points" is based on the length of units per inch evolved;Divide 1 inches (25.4mm) 8, 4 points 4/8, or 1/2 inches, equal to 12.7mm.Therefore, "4 points ball valve" diameter is 12.7mm.
Q:Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?
Yes, but not in a high temperature for a long time, like more than 180 degrees centigrade. Because the gasket can not be used after deformation, it will cause valve leakage.
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
