Q:What valves are needed on the construction site?
Order valve flow1, customers have special requirements for products, must provide the following instructions in the contract: a) b) the length of the structure connection form C) nominal diameter, full size, shrinkage, pipe size d) using medium and temperature and pressure range E) test, inspection standards and other requirements.2, the factory can be configured according to customer specific requirements of various driving devices.3. If the customer provides the type and model of the valve to be determined, the customer shall correctly explain the meaning and requirements of the model and sign the contract on the condition that both the supply and demand sides agree.4, futures, order customers, please call the letter in detail to tell you the required valve model, specifications, quantity and delivery time, location, factory information, billing information, delivery address. And in accordance with the total amount of 20% of the predetermined amount or full amount of money, timely import our factory account, and the rest of the payment before shipment, import, in order to arrange delivery in time.

Q:How to quickly identify the types of valves?
You can look through shapes, signs, or buy a valve manual
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:What is the difference between valve j941H-40 and j41H-40?
Valve design manual showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one
Q:The valve has a clear opening and closing sign. What does this sentence mean?
Not only on the valve is enough to mark, here means that at the scene can see the installation of the pipe network on the valve open or shut?!
Q:What valve is the VENT?
In order to reduce the leakage point, sometimes before the factory will be welded to death.DRAIN position must be in the lower position of the valve body, is generally able to reach the lowest point.
Q:Who knows what the DE stands for in the valve DE50?
Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.De is the nominal diameter, that is, the outer diameterGenerally speaking, from small to large specifications are as follows de (mm)De20, de25, de32, DE40, de50, de63, de75, de90, de125, de110De160 de200 de250 de315...... Until de800
Q:The water pipe in the house is broken.
You really want to go to the big water to fix the valve and be prepared for the follow-up, just in case
Q:Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?
In general, the exhaust valve (large diameter) and a maintenance valve, normally open,
We have advanced technologies, facilities, resources and talented personnel for processing, developing, studying, designing and manufacturing of different kinds of valves. Our main products are wafer and lug type butterfly valves, slim pinless butterfly valves, flanged valves, gate valves, check valves, ball valves, and Y-strainers in medium and low pressure rate.
