Q: What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?: Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel

Q: Soft sealed gate valve and hard sealing gate valve which good?: If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.

Q: The difference and use of gate valve and stop valve: Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.
