Q: What are the working principles of the electric gate valve?: We see you what type of electric valve, is integral or ordinary type, if the overall type Denso took power on the line, is generally 380V and 220V power supply, and then according to their own needs and then open the signal line, in place and closing in place and remote control line, valve position feedback signal the commonly used 4~20ma over torque protection fault signal.

Q: Valve flange drawing n- up to what: A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size

Q: The difference between flanged gate valve and common gate valve: Flange gate valve and ordinary gate valve difference is that the flange gate valve of good quality, durable and easy to install, but the price is a little high, generally used for large pipelines. Common, also available, such as small caliber, easy to change places.

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: What kind of gate valve is Z6CS-H102?: Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr

Q: What is the standard for ductile iron gate valve set?: Fujian - mark light - valve for you to answer:Whether it is the next shot or dark bar, directly flanged valves can be installed, usually apply eighth copies, if the industrial pipeline is apply sixth copies, sixth copies to apply separate sets of flanges and bolts (bolts independent fee).

Q: Installation and operation instructions of knife gate valve: 3., check the packing parts require compaction, not only to ensure the sealing of the packing, but also to ensure that the gate open flexible;4., before installing the valve, users must check the valve type, size and attention to the media flow direction, to ensure consistency with the valve requirements;

Q: The valve safety valve check valve + + + = exposed part of a water pump adapter? Five: Generally do not require safety valve, just install exhaust valve in individual places.

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 an inverted seal gate valve?: The inverted sealing gate valve is provided with an inverted sealing device, and when the valve is fully opened, an inverted seal is formed, and the filling can be changed under the normal operation of the system.
