Q: What's the meaning of the "single valve"?: So called" screwed joint"Valve single order, refers to the valve with a live joint, is a more convenient valve assembly and disassembly.

Q: What do the Z, J, H and D represent in the valve type?: 7, pairs of clipsThe transmission modes of valves are code 9, 6 and 3 respectively:9, electric, 6, pneumatic, 3, turbo wormBody material code Z, K, Q, T, C, P, R, V, respectively:Grey cast iron, malleable cast iron, ductile iron, copper and alloy, carbon steel, stainless steel, chrome nickel chromium nickel molybdenum stainless steel, chromium molybdenum vanadium steelSeat seal or lining code R, T, X, S, N, F, H, Y, J, M, W, respectively

Q: Ketem valve relative to other valve companies in the industry what are the advantages?: The electric actuator built-in servo system, no need to add servo amplifier, input 4-20mA signal and 220V AC power supply can control the operation. Compared with the ordinary electric ball valve, the utility model has the advantages of compact structure, small size, light weight, close distance between the valve seat and the end face flange, less material retention, superior sealing performance, etc..

Q: Who knows which kind of water valve is good?: Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.

Q: What are the types of valves?: 1.1 classification by purpose and functionx09 (1) cut-off valve is mainly used to cut off or switch through the media flow, including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, needle type instrument valve, etc.x09 (2) control valve is mainly used to regulate the flow of medium, pressure, etc., including regulating valve, throttle valve, pressure reducing valve and so onx09 (3) check valves are used to prevent backflow of media. Check valves with various structures are includedx09 (4) diverter valves are used for separation, distribution, or mixing of media, including distribution valves and traps for various structuresx09 (5) safety valves are used to protect the medium against overpressure. Various types of safety valves are included1.2 classify by main parameters

Q: What is a heavy body valve?: Heavy body valves are heavy duty valves. This is the size of the valve, weight, wall thickness are linked, in general, the gate valve and cut-off valve is divided into heavy, medium and light three, other valves are not so distinguished.

Q: How does the valve open?: This is a three pass, not a valve. It doesn't open often or often closes and there is no opening or closing. Can change the same caliber of the valve, you can use the handle switch.

Q: How to carry out the valve strength test and air tightness test?: All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed

Q: What does valve 41F-40C mean?: Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
