Q:What's the difference between a medium-sized ball valve and a heavy ball valve?: It's almost certain that you made an inquiry at the small valve manufacturer in Wenzhou.In fact, the main wall thickness is differentThe so-called heavy, is in accordance with the GB/T12237 Petrochemical ball valve wall thickness to designThe so-called medium-sized, is in accordance with the GB/T12224 steel ball valve wall thickness to design, two wall thickness of some difference, plus a little steal material, sphere do hands and feet, the price can be much lower.There is a light, that is the material does not meet the standards, basically sold to plumbing builders.

Q:Would you please tell me why the spring is placed in the valve seat? What's the function?: Valve seat on both sides should be added spring, the seal pushed to the valve core to seal up, so put the spring.

Q:Into the tap valve, with globe valve or ball valve?: Water valve at home as far as possible not to use the form of valve, gate valve for water, slag better, shut down with the next valve and ball valve.

Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?: Supplement: the above mentioned is just a pure design, such as the novice to do the design, checking and calculating of the general will, in fact in the reality of the design, the valve products have been very mature, as you say these are size, can refer to the same type with the specifications of the product parameters so, the more accurate calculation, experience is more important than calculation.

Q:What are the differences and advantages between O ball valve and V ball valve?: 2 、 the switch is quick and convenientThe ball just rotated 90 degree is completed fully on or off, so it can achieve rapid opening and closing.3, good sealing performanceMost of the valve seat by four poly ethylene (PTFE) elastic materials, commonly known as soft sealing valve. Soft sealing valve has good sealing performance, roughness and machining precision and sealing surface of the valve is not very high.4, long lifeAs a result of polytetrafluoroethylene (PTFE or F4) has good self lubrication, and friction coefficient of the ball is small. Due to improved processing technology to reduce the ball roughness, thereby greatly improving the service life of the ball valve

Q:What is the nominal pressure 1.6p of a ball valve?: Nominal pressure: reference value relating to the pressure resistance of a piping system. For ease of use, usually the priority of the R10 series is taken. Nominal pressure refers to the pipe in the two temperature (20 degrees Celsius) when the water delivery pressure. If the water temperature is between 25 and -45 degrees, the coefficient of temperature drop should be adjusted to correct the working pressure.

Q:Can the check valve replace the ball valve?: Can not be replaced, because the ball valve to play a maintenance, cut off the role of water sources

Q:The two valves are available for the flow of the electromagnetic valve switch, I contact more, found for water solenoid valve are caged water, to repair several times because of impurities or newly installed pipeline with raw materials flowing through the valve, close the valve body when not to rely on Yan, a seepage water tank to diffuse phenomenon!I am looking for a replacement, I think the electric valve should be a good choice, not used to a conclusion.Please use the electric ball valve to talk about friends, or for the two kinds of friends who have an understanding to talk aboutOr there is no better substituteThere seems to control the solenoid valve and electric valve is not the same, the solenoid valve is normally open and closed to control the electric valve is controlled by the trigger (like), if used to replace it, what is the controller?: Solenoid valve on the medium cleanliness requirements are very high, when the water is not clean, easy to leak. You use the solenoid valve is leaking, that's the case.If you have an air source, use pneumatic angle seat valvesIf only the power supply, the electric ball valve.Electromagnetic valve is electromagnetic rail, electric suction from the electromagnetic core, so that the valve openThe electric ball valve is driven by the motor to drive the valve open. If only switch, then do not need to install any controller, when buying, must explain is the switch ball valve.This answer was net friend adoption

Q:About the characters on the ball valve (what do s and O mean?): That's almost what it means. To be exact, S is SHUT and O is OPEN

Q:Where are the natural gas ball valves produced?: Do not know, do not know, may be in the area where the factory is TrumanHope to solve your problem.
