3. Feature:

1, the rubber valve adopts the whole package, its good with performance and precise geometry size to ensure reliable sealing, long service life.

2, simple and compact structure, convenient operation, easy installation and easy maintenance;

2, at the bottom of the tank, large flow area, sizing smooth transition, no dirt accumulation phenomenon, small flow resistance;

3, resilient seal, zero leakage and long service life;

4, the valve inside and outside spraying epoxy resin coating, coating rubber damper as a whole, to prevent the corrosion and rust polluting the medium, not only for drinking, and can be used in the sewage system;

5, stem with three "O" type circle in sealing, low friction resistance, small operation torque, easy, for opening and closing without stuffing box leakage phenomenon, and under the condition of pressure and constant water replace o-rings.

6, soft-sealing gate valve can be used for adjusting.

7, have automatic adjustment function, through the guide valve plate and valve body, automatic calibration. Screw nut is embedded on the valve plate to ensure the center line of the valve stem and valve body centerline of automatically.

8, ensure that opening and closing more than 50000 times without damage, the valve plate closed tightly.

9, paint on the surface of the valve has the good, using polyester paint, paint color to blue.

Q:Soft sealed gate valve and hard sealing gate valve which good?
If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.
Q:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
I don't know why it was designed. Provide you with some information you refer to, I do not know if it works for you1, stop valve and gate valve are very expensive, more than DN50 can make a lot of money2, butterfly valve is only more than DN50, no small, there may be, but I almost can not see the market.3, like DN150, DN200 such cut-off valve, gate valve is very large, and the butterfly valve is relatively light, installation can save the cost of the block, the valve itself saves too much money.4, but most of the butterfly valve used for a long time are closed.
Q:What is the difference between the cut-off valve and the gate valve?
What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.
Q:Does the relief valve have a gate valve?
With the ball valve, needle valve, with the valve did not see, but there should be some.
Q:What is the difference between gate valve and gate valve? Is it the same valve?
Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.
Q:What kind of valve is gate valve? Is it different from the cut-off valve?
Gate valve is applied to the big diameter pipeline valve, the valve is generally used in small pipe diameter pipeline, their internal structure is different, the valve can not regulate the flow of water, the valve can be. If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.
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 does gate valve DN80-PN16-QT450 mean?
The outer diameter of the pipe is usually 89mm;"PN16" means the nominal pressure of the gate valve is 16Mpa;QT450 QT said, nodular cast iron, tensile strength is more than 450MPa 450.
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:What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
