Q:What are the differences between the gate valve and the cut-off valve?

The operating principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outletAt the same time, usually with the cut-off valve instead of gate valve, but the valve can also be used instead of cut-off valve. Valve sealing performance better, but the size is generally not large, the size of the gate valve can be done great.The main difference between them lies in:1, different structure, gate valve structure is more complex than the height, larger size, from the appearance point of view than the cut-off gate valve is short and high, especially the gate height space needs a higher open bar, the selection in the installation space under the condition of limited attention to.2, sealing surface, valve in the opening and closing valve and the valve seat surface always contact and friction between the sealing surface, and thus easy to wear, especially in close off the valve when the valve before and after the great pressure, sealing surface wear is more serious. And the valve once the valve is in open condition, it's seat and disc sealing surface between, not in contact,

Q:What does gate valve Z41H-40 mean?

Q:Gate valve z45h-10dn250 length of the body?

Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal

Q:The legend of gate valve and stop valve

The working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
