Q: DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?: The outer diameter of the ball valve depends on what kind of flange you useAt present, the domestic commonly used flanges are marked with JB/T (formerly mechanical industry standard), GB/T (GB), HG (Ministry of chemical industry).

Q: Manual ball valve type: Class400, 20 ', what does that mean, industrial knowledge?: The pressure rating of the valve type and American StandardIt's a 20 inch, 400 pound valve20 inch =DN500 (nominal diameter)400 pounds equivalent to nominal pressure PN64 Mpa

Q: The difference between ball valve Q341F and Q347F: Ball valves Q341F and Q347F are straight through flow, worm drive, flange connection, soft sealing form. Different from Q341F, it is a floating ball structure, and Q347F is a fixed ball structure.Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve;

Q: Ask you engineer, 150mm diameter ball valve or butterfly valve, installed in the water supply pipe, water pressure 0.4Mpa, driven by the electric actuator, should much force distance?Sincere thanks, enthusiastic support of net friend.: 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: Home PPR pipe ball valve, which is good?: Zhejiang harmonious tube industry, the quality is very good, the price is also affordable, I installed, I do not know how many. Ball valve broke, it must be cut, from the connection, the valve is broken, and another spool can be used

Q: What is the diameter of the 2 inch ball valve?: 2 inch ball valve, diameter is two inches.Turn left and turn right |Ball valve, standard GB/T21465-2008 "valve terminology" is defined as: open and close parts (spheres) driven by the stem, and around the axis of the ball valve to rotate the valve movement. 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. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.Turn left and turn right |The answer is recommended by He Xiaoqiang, a member of the science education category

Q: Would you please tell me why the spring is placed in the valve seat? What's the function?: To put the spring ball valve must be big ball valve! Or fixed ball valve?! Fixed ball valves, as the name suggests, the ball of the valve is fixed, not right and left swing! Therefore, the valve seat should be added to both sides of the spring, the seal pushed to the valve core to seal up! The spring can also reduce the impact force of the material of the valve Wenzhou Songjiang pipe valve Co., Ltd. specializing in the production of stainless steel ball valve! Songjiang brand valve! Globe valve！ Gate valve! Check valve! High temperature ball valve! Electric ball valve! pneumatic valve

Q: PE pipe size diameter 3/8, diameter 1/4, material: low density polyethylene, pressure 170psi;Valve material: copper, and PE pipe connection interface with lock nut.Is this connection reliable? Will the pipe break due to excessive compression? Are there any requirements for the size of the joint and the size of the nut?: After the impact, for a period of time, PE pipe cracking phenomenon, this is what causes? This is connected to the tap water.Chasing the answerWhere is it cracked?!

Q: What's the difference between a medium-sized ball valve and a heavy ball valve?: Medium and heavy duty difference is several kilograms, heavy material is not false, and temperature resistance, and pressure performance is better, long life!

Q: For example, how many sizes and pressures are used in the two piece?: First of all, the difference between a ball valve and two chip, three chip ball valve is a ball valve flow, the internal structure of the necking design belongs to the design, the same diameter ball valve products must be smaller than the other two kinds of ball valves flow more. Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
