FAQ

Ball valve specifications 1/2 inches corresponding to DN?
I know that. 1/2 stands for DN15. 3/4 stands for DN20. Ha ha, unfortunately no points
What does "q341" and "q347" mean?
Valve type explanation:Q stands for ball valves;3 represents worm gear drive;4 represents flange connection;1 represents straight through floating ball, and 7 represents straight through fixed ball.Therefore, Q341 is a turbine driven flange straight through floating ball valve, Q347 is a turbine drive flange through fixed ball valve.
What is the service valve?
I said that the pipeline on the pipeline pigging long-distance, pigging requires this launcher equipment, is the pigging ball into the barrel inside, and then through the process so that the pig into the pipeline, detection of pipeline cleaning or other purposes.
Are ball valves and float valves a thing?
Ball valves and float valves are not a thing.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. floating ball valve is a ball without supporting shaft, the sphere was two seat clamping, which is "floating" state, it is mainly used in the pipeline to cut off, distribution and change the direction of media flow. Floating ball valve mainly has seat seal design, reliable reverse sealing valve, sealing rod, fireproof electrostatic function, automatic pressure relief and locking device and other structural features.
What's the advantage of using an electric ball valve?
The electric ball valve uses electric control, not very suitable in very dangerous conditions, the electric ball valve belongs to the valve control, remote control, manpower, and convenient, and now all the enterprises have to use the valve in the automatic control to change
One stainless steel ball, two pieces, three pieces of difference, use
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
Where can I buy this Y filter with a ball valve?
This valve is added after the filter, directly on the flange welding joints or holes in the flange is connected with a ball valve tapping, can double wire, because the Y type filter is standard, relatively good buy, relatively less modification
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
