FAQ

DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
In addition to the three common, flange standard complex, a long story.All kinds of standards, there is a little difference in thickness, diameter of flange, bolt hole number, but the flange bolt hole parameters of the same pressure level (bolt circle diameter K, bolt diameter L, bolt number N) are the same.
Is the ball valve switch in front of the water meter or after the water meter?
It's in front of the water meter. What's the problem?.
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
What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
In general, both sides of the ball are wire interface, and hot melt ball valve on either side or side of the live connection with PP-R short tube, as a hot melt interface, so called hot melt ball valve. As for the use, there is no obvious difference, but the connection is different.
Three electric ball valve type T and type L what is the difference?
Ball valve: including straight through, three, etc.. Three way ball valve: including L type, T type. Therefore, the three way ball valve is a kind of ball valve! But the regular ball valve means straight through.
For example, how many sizes and pressures are used in the two piece?
A piece of ball valve, the current market pressure of most products below 6.4MPA, two piece ball valve about 12.8MPA products are also common, there are 20MPA, three pieces of ball valves are mostly below 6.4MPA. Know the characteristics and shortcomings of these three kinds of ball valves, you can completely choose according to your own needs.
Butterfly valve, globe valve, ball valve used what is different
Butterfly valve, globe valve, ball valve used in different occasions:1. valve (Butterfly Butterfly) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.
The difference between a cricket valve and a constant pressure valve
Ball valve for ball ball column shape and called, is mainly to be closed, and often switch when the fluid flow control to throttle function and design, is the main characteristic of effective throttling, to minimize and reduce the phenomenon of drawing valve and valve seat dip (wash) inhibition, but because of the seat is parallel to the line, change the flow of fluid through the valve seat will be in class.
