Q:What are the structural differences between parallel and wedge valves?: The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.

Q:What does gate valve DN200PN160 mean?: DN200 refers to the nominal diameter of the valve, the unit is mm, PN160 refers to the valve tolerance pressure, the unit is 1/10MPa.

Q:Does the tap belong to a stop valve or a gate valve?: If it is about to pull open and close, it is cock valveIf it is rotated up and down, it is a stop valve

Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?: when the envelope from the introduction of civil air defense, air defense should be set in the side of retaining structure; through the protection unit between the closed wall, should be installed in the pipe walls on both sides of the door closed;2 protection valve nominal pressure shall not be less than 1.OMPa;

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: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.

Q:Gate valve z41t what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy

Q:Which is the most expensive, check valve and gate valve?: In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124

Q:Function of signal butterfly valve and gate valve: The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. It can be used as regulating and throttling devices in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. It is widely used in high buildings, fire protection systems and other piping systems that need to display valve switching status.

Q:What are the meaning of the cast rigid gate valves z41h-16c?: According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel
