Q:What's the difference between a copper ball valve and a stainless steel ball valve?
The difference between copper ball valve and stainless steel ball valve:1, they use the material is completely different, steel ball valve adopts copper, stainless steel ball valve is stainless steel.2, copper ball valve corrosion resistance is excellent, switch operation is smooth, labor-saving, durable without leakage. Stainless steel will not cause corrosion, pitting corrosion, corrosion or wear, and high temperature resistance. The average stainless steel is more expensive.3, according to the same pressure environment, the price is stainless steel cheaper, and copper ball valve medium temperature is much higher than the stainless steel ball valve, if the medium temperature is too high. Copper ball valve must be used! If the medium temperature is not more than 80 degrees. With stainless steel ball valve on it
Q:Ball valve leakage of this place, how do?
The seal on the valve body is broken. Screw it down and change the gasket
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 are the types of vacuum ball valves?
Vacuum ball valve refers to the work pressure is lower than the standard atmospheric pressure, forming a certain vacuum ball valveVacuum ball valve models are GUD, GDQ, KF16, GU, KF and so onVacuum ball valve type has electric, manual, pneumatic, such as GU manual vacuum ball valve
Q:Ball valve specifications 1/2 inches corresponding to DN?
[1] 1/2 is DN15, 3/4 is DN20, and 1 is DN25.[2] ball valve: ball valve (ball valve in the field of marine engineering and ships should be cut-off valve), refers to the ball with a circular hole for opening and closing parts, the ball with the stem rotation, in order to achieve Kai [1] closed action of the valve. Standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the square ball valve for the axis of the rotation of the valve.". Use can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.
Q:What is the force distance of a ball valve with a diameter of 150mm?
Reference: ball valve 1000N on the line, butterfly 250N canThis valve with the switch torque is related, each manufacturer according to the workmanship, process switching torque is not the same.You can refer to the recommended value of the actuator manufacturer
Q:Ball valves, butterfly valves, gate valves, stop valves, check valves, etc., are used where ah?
Q:Is the ball valve switch in front of the water meter or after the water meter?
the owners of their own decoration or repair, in front of the water meter is generally C type locking valve or valve, if less water, property control, no special key you open
Q:What does one inch of an ice ball refer to?
Ball valve inch refers to the nominal diameter of the valve is 1 inches, that is, DN25 valve1 and 1/2 is DN40's.. More than an inch on a pipe. The valve is half done with DN
Q:Hello, I would like to ask the household tap water valve selection of stainless steel ball valve or brass ball valve is better, thank you
I have used two kinds, but stainless steel gate valve is better. Note that it must be made of stainless steel 304. I bought more than 300 yuan a gate valve. Total valve, no way to save money.
