Valve is a opening and closing the gate assembly, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, discomfort door parameter varies, usually 5 degrees, the medium temperature is not high for 2 ~ 52 '. Improve the process, make up the sealing surface angle in the process of the deviation, which is called the gate.
Motion editing valve closed, the sealing surface can only rely on media pressure to seal, which only rely on media Z41h flange wedge gate valve pressure on the sealing surface of the disc to the other side of the valve seat to ensure the sealing surface, which is self sealing.
Most of the valve is forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface of the seal.
Movement: gate valve with the valve stem together for a straight line movement, also known as the gate valve.
Usually on the lifting rod with trapezoidal thread, through the valve on the top of the nut and the body of the guide slot, the rotating motion into a linear motion, that is, the operating torque into the operating thrust.
When the valve is opened, when the gate height is equal to 1:1 times the diameter of the valve, the fluid passage is completely free, but at the time of operation, the position can not be monitored.
Actual use, is the apex of the stem as a sign, that is, the open position, as its fully open position. In order to consider temperature changes occur locked phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as a fully open valve position.
Therefore, the valve fully open position, according to the location of the gate (that is, the stroke.
Some gate valve stem nut is located on the gate, the hand wheel rotation to drive the valve stem rotation, and so that the gate to upgrade, this valve is called the rotating rod gate valve or called the dark bar gate valve.

- 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: What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
- 9- electric (drive)4- flange connection (connection)1- plain wedge single gate valve (valve structure)H-Cr stainless steel (sealing surface material)25- nominal pressure is 25 kg, or 2.5MPa;DN250- valve by 250mm
- Q: Installation and operation instructions of knife gate valve
- 3., check the packing parts require compaction, not only to ensure the sealing of the packing, but also to ensure that the gate open flexible;4., before installing the valve, users must check the valve type, size and attention to the media flow direction, to ensure consistency with the valve requirements;
- Q: Stainless steel gate valve DN150 200300 weight, who knows?
- It depends on different materials and pressure levels. 304 material, high pressure weight will be much heavier.
- Q: Is the gate valve clockwise or closed?
- In general, the valve is clockwise turn off, in the case of special requirements under the opening.
- Q: Why the valve can only be fully open and fully closed valve can adjust the flow?
- Gate valve, stop valve are switching type valve, adjust the flow can not talk about, can only do so called throttle.You say "stop valve" or "translation" problem, in English, globe valve and valve word is often the same.
- Q: What's the difference between the knife gate valve and the stop valve?
- Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.
- 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 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.
- 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.
