Q: The difference between cut-off valve and gate valve: Structurally, the gate valve for the gate, down to the front and back seat seal; globe valve with spherical, taper and flat spool, down to the valve seat seal. Functional stop valves are generally used for pressure flow control. Gate valves are used for isolation.

Q: How about the model of stainless steel gate valve?: Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.

Q: What is a protective gate valve? What is gate valve knowledge?: Door gate, refers to the design of anti blocking nuclear explosion shock wave from the pipe into the project inside the valve, composed of a valve body, valve seat, valve plate and wave absorbing device, wave absorbing device leakage hole in the valve body, valve leakage hole is a cylindrical hole, wave valve has two door sealing groove between the cylindrical hole and wave valve double seal ring seal, between the valve body and the flange is double sealing ring seal.

Q: What does gate z41t-10 150 mean?: According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150

Q: What is the difference between an elastic gate valve and a rigid gate?: General rigid gate used in the temperature is not too high, the pressure is not too large occasions, flexible gate used in high temperature, high pressure, or relatively high sealing requirements.Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.

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: What is the difference between gate valve Z41T and Z45T?: Valve Z41T and Z45T difference is that "41" is dark rod, that is, the screw is not out of the turbine,"45" is the bright rod, that is, the screw out of the turbine.Common points are copper sealed gate valves.

Q: What does the gate valve SZ45X-1.0 stand for?: A modelModel SZ45T-1.0, especially in DN100 ~ DN300 piping, soft sealing gate valve shall be used

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: What are the types and product categories of knife gate valves?: Knife gate valve drive mode:Manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electronically controlled, hydraulic and pneumatic drive. Knife gate shape: bright rod, dark rod two kinds. Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine and so on. Knife gate valve seal: hard sealing, soft sealing, single-sided sealing, double sided sealing and other material seal.
