Q: What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve: Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.

Q: What does gate valve Z41H-40 mean?: Z - that means gate valve (the initial letter of Zha)4---- is the connection form, which means flange connection1---- form of structure, which means Plain Bar wedge type rigid single gate valveH---- sealing surface overlaying ferrous carbide (initial letter of alloy steel He)40---- nominal pressure is 40 kg, or 4.0MPa, that is, PN10 at 250 degrees Celsius, the maximum working pressure is 40 kgThe material is cast carbon steel

Q: Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

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 is the difference between cut-off valve and gate valve?: Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way

Q: Stainless steel gate valve DN150 200300 weight, who knows?: It depends on different materials and pressure levels. 304 material, high pressure weight will be much heavier.

Q: What is the difference between an elastic gate valve and a rigid gate?: General rigid gate used in the temperature is not too high, the pressure is not too large occasions, flexible gate used in high temperature, high pressure, or relatively high sealing requirements.Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.

Q: What's the meaning of the gate valve model z41x 16Q?: Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)

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

Q: What are the differences between the gate valve and the cut-off valve?: 3, the valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for a variety of occasions, such as the valve rod the dark bar valve, gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume. Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure and other occasions.4, the cut-off valve is able to stop and adjust the 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 sealing valve has the characteristics of one-way sealing effect, so that the utility model can prevent the working substance from flowing upstream
