FAQ

What's the difference between angle valve and ball valve?

Ball valve, as its name suggests, is the shape of a ball valve, water from the hole in the middle of the ball out, usually the handle to control the opening and closing. But the ball valve can only be switched on and off, and can not adjust the flow. To put it plainly, you take it half open and half closed, and its flow is not about 50%, and fluctuates greatly. In addition, if the ball valve will be half closed, it will damage the ball valve, greatly shorten its life. Ball valve is mainly used for heating hot and cold water inlet pipe.

DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?

So you must first determine the pressure level of your ball valve, and then determine the valve flange used standards, and then you can determine the basic parameters of the ball valve flange.

PPR ball valve which face is open, which face is closed, there is a o, there is a s, which is off, ah, which is open, well intentioned people told me that the original finished by forget

Hello, I am glad to answer for you. O is on, s is off. I hope I can help you.

Allowable leakage on ball valves: what does CLassVI mean?

This is the valve leakage level, level VIThe GB/T4213-92 standard specifies six grades for the valve leakage. The specific requirements are shown in the standard table. The lowest level is level I, without specific requirements; the highest level is grade VI, i.e., the bubble grade.

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

Which is more cost-effective electric ball valve?

All kinds of Lady valve manufacturers.The company has strong technical force, with adequate and sophisticated machining equipment as the premise, to provide a strong guarantee for the production of high-quality products,

Can the ball valves be used in heating?

Ball valve because of its geometry and the sealing of the pipeline is relatively good, so many applications. The heating is fine, of course.

Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!

I don't know. Solid geometry will happen. God knows me. Suddenly, barriers and French goods
