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:Analysis of the advantages of elastic seat sealing gate valve?

When the elastic seat sealing gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the flashboard is pressed to the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self sealing.

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.
