Specifications

Gate valve

Gate valves supplied by our company are available in temperature classes L, P, R, S, T, and U specified in API 6A.

Gate valves to be used in the 350°C or 650°C high temperature can be supplied on request. Fire-proof gate valves also can be supplied to API 6A.

Gate valves manufactured by our company are available in 2000psi, 3000psi, 5000psi, 10000psi and 15000psi working pressure, material classes from AA through FF, product specification levels (PSL) from 1 through 3 and performance requirement (PR) 1, 2.

Both sealing faces of gate are wedge type structure,and hand wheel can be loaded to adjust the fastness of attachment of gate and valve seat.

The sealing face of gate and seat is overlaying-welded with hard alloy with erosion and corrosion resistance

Q:What is gate valve (with force transfer joint)?
The force transfer joint is mainly used for the loose connection of pumps, valves and other accessories.
Q:What is the difference between gate valve and gate valve? Is it the same valve?
The same, very few people call gate valve, all call gate valve.
Q:The difference and use of gate valve and stop valve
Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference
Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
Q:What's the meaning of flexible z45x-10q door valve?
Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
2, soft sealing gate valve at the bottom of the pit. No accumulation of slag material, valve opening and closing of the failure rate is low;
Q:Function of gate valve
The valve (including the valve and valve) is a fluid pipeline control device, its basic function is to connect or cut off the pipeline medium circulation, changing the medium circulation, change the direction of the flow medium, medium pressure and flow regulation, to protect the normal operation of pipeline equipment.
Q:The legend of gate valve and stop valve
Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions. The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve.The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by.
Q:Is the gate valve flanged?
The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.
