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:What is the specific difference between floating ball valve and fixed ball valve?
Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve
Q:What are the inside parts of the ball valve?
The universal ball valve includes the stem, valve ball, seat, seat seal and packing.
Q:Would you please tell me why the spring is placed in the valve seat? What's the function?
The spring can also reduce the impact of the material on the valve.Ball valve (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 for rotation of the valve.". 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.
Q:Ball valves, butterfly valves, gate valves, stop valves, check valves, etc., are used where ah?
Q:Ball valve Q41f and Q11f difference, whether universal?
Yes, it works,The main valve interface shall be in line with the interface on the pipe,No, the valve is a thread, and the pipe joint is flanged, so it won't work.
Q:Replacement method of PPR hot melt ball valve
1, need to replace the valve, if the valve is flange or wire connection type, directly open flange or loosen the screw, the ball valve can replace a broken;
Q:Check valve, ball valve, check valve are used in what place, ah?
The cut-off valve is generally used in the inlet pipe, the outlet valve is generally used in the official website, convenient switch, check valve is to allow water to flow past the water directed, anti back, generally used in vertical pipe, valve equivalent pump: the following are the cut-off valve check valve valve identification pictures, please note.
Q:DN15 ball valve with a bit of outer wire
Is. But we usually use engineering diameter in our country. A few is the imperial system, in addition to the domestic veteran workers still use, and now are using GB size.
Q:What is the difference between ball valve and butterfly valve?
The ball valve and butterfly valve butterfly valve ball valve and the maximum difference between the difference between the two is the valve opening and closing parts is a panel, which is a ball valve, butterfly valve plate and the ball valve is rotated around its own axis for movement of the ball valve is a spherical sealing surface.The valve (Valve) is a mechanical device that controls the flow, flow, pressure, temperature, etc. of a fluid medium. The valve is the basic component of the piping system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
In industries where performance, quality and reliability are essential, the ball valves and other products are secure choices. Each valve is manufactured according to strict technical specifications, guaranteeing full customer satisfaction. Having been checked for more than 5 times from beginning to the end, our products ensure 100% high accuracy.As a result of on-going modification and the upgrading of current valve designs, together with the development of new valves, We offer the highest degree of sophisticated products that meet customers' requirements.
