Q: The difference between cut-off valve and gate 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.

Q: What is the difference between gate valves Z41W-16R and Z41W-16P?: According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.

Q: Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?: In the standard JB/T5296-1991 "universal valve flow coefficient and the flow resistance coefficient test method",

Q: Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you: There is mail sent me, send you a specific

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 does the gate valve 150# mean? Is it stress PN? What's that, PN16 or?It's better to have some specific links, thanks!: I think PSI is equal to 150#The sign behind is "PSI"You Baidu "ANSI standard pressure, pound scale and nominal pressure relations table" will knowI'm new, too, I understand

Q: What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?: Z15T stands for manual, internal thread connection, dark wedge single gate. The sealing surface is made of copper alloy. The nominal pressure is PN1MPa;Z15W-16T for manual, internal thread connection, dark wedge type single gate, the valve body material is copper alloy, the valve seat sealing surface material directly processed by the valve body, nominal pressure is PN1.6MPa;Z45T/W-10 stands for manual, flange connection, dark wedge single gate. The valve body is made of copper alloy, and the valve seat face material is directly machined by the valve body. The nominal pressure is PN1MPa;Z41T-10 stands for manual, flange connections, plain wedge single gate, sealing surface material is copper alloy, nominal pressure is PN1MPa.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate

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: What is the gate valve for the DN65 hydrant?: DN150, of course. Ask me about fire protection

Q: Acid resistant alkali valve gate valve: A products have few connections and good overall steel quality.B closure speed is fast.C opening limit mechanism is convenient, flexible and precise.
