Q:GB 300 gate valve, a multi?

GB DN300 flanged gate valve, PN10 manual 245kg bevel gear 315Other pressure levels, please specify specific pressure.Wenzhou Chaoda group Agel Ecommerce Ltd to provide the answer:

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:Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?

We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection

Q:What is wire feed gate valve? What do you say in French?

It should be the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connectionI only know their English, I'm sorry I can't help youBox thread valveFlange valve

Q:Why does the centrifugal pump start and stop in the case of closing the gate valve?

The centrifugal pump starts and stops in the case of closing the pump outlet valve. Start off the pump outlet valve is to reduce the starting current, stop when the pump is closed, the outlet valve is to reduce water hammer, prevent blade from bad.

Q: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.

Q:Why the valve can only be fully open and fully closed valve can adjust the flow?

You said the cut-off valve is that the spool is rotating rather than vertical movement structure?Theoretically, the flow regulation can be realized by controlling the position (angle or distance), and all of them have mature products.

Q:The difference between flanged gate valve and common gate valve

General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.

Q:What type of flange does it fit with the gate valve?

According to the welding plate flange, flange material selection of piping material.

Q:Gate valve is gate valve, gate valve specifications, model code is generally what?

Valve lock valve and gate valve. According to the code, the domestic valve type standard, valve type valve is composed of valve type, drive mode, valve connection, valve structure, sealing material, body material code to said gate type code Z.Gate valve: gate valve is one of the most commonly used shut-off valve, mainly used to connect or cut off the pipeline medium, not used to regulate the flow of media. A wide range of pressure, temperature and diameter is used, especially for medium and large diameter pipes.1, the main characteristics of gate valve(1) fluid resistance is small. The through hole of the gate body is straight through, and the flow direction of the medium does not change when flowing through the medium, so the flow resistance is smaller.(2) opening and closing is more labor-saving. When opening and closing, the direction of valve plate movement is perpendicular to the direction of flow of medium. Compared with the opening and closing more effort.(3) medium flow direction is generally unrestricted. The medium can flow in any direction from both sides and can achieve the purpose of switching on or cutting off. Easy to install, used in the flow direction of the medium may change in the pipeline.
