FAQ

What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?: Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.

What's the difference between open rod gate and dark rod gate valve?: There are several differences between the open bar gate valve and the dark rod gate valve:1, the bright bar gate valve can see the screw rod, but the dark rod can not see the lead screw;2, clear shot valve is threaded through the drive rod and the steering wheel to raise or lower the valve; dark rod valve in the switch when the steering wheel is connected with the valve stem is relatively fixed, it is through the stem of a fixed point in the rotation to drive the valve to move up and down to complete the opening and closing of the;Drive screw

Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?: Water supply and drainage and civil air defense works, now with the dark rod type elastic sealing gate valve more.Compared to the gate and the traditional carve type or parallel double gate plate valve has the following characteristics: 1, soft sealing valve body, valve cover using precision casting foundry, a molding, no mechanical processing, do not use sealed copper ring, saving non-ferrous metals;

What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

What are the features and uses of the gate valve?: 1) advantages: sealing performance than the cut-off valve, the fluid resistance is small, open and close more effort, full sealing surface by the erosion of media, media flows from the restrictions, with double flow, small structure length, wide application range. 2) disadvantages: high size, open need a certain space, opening and closing time is long, in the opening and closing, the sealing surface is easy to erode and scratch, and the two sealing pairs bring difficulties to the processing and maintenance.3) use: gate valve is generally used in the caliber of DN15-1800mm pipes and equipment, and its dosage is great, mainly cutting off function, not allowed to throttle.

Which is more expensive, bronze gate valve or brass gate valve?: But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.

The difference between flanged gate valve and common gate valve: Flange gate valve and ordinary gate valve difference is that the flange gate valve of good quality, durable and easy to install, but the price is a little high, generally used for large pipelines. Common, also available, such as small caliber, easy to change places.

What kind of copper gate valve copper content standards, there are no national standards?: Copper gate valves are made of brass and bronze, and the national standard does not require copper content.
