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?: First, 170psi pressure is not great, not excessive extrusion and rupture of polyethylene, but there will be stress relaxation phenomenon, is a long time there will be some loose, suggest you nut and pipe with tight mechanical connection is good, the data has not been studied, can only give you a suggestion: 24-48 hours after the installation is complete then a proper tight.

Q:What are the uses and characteristics of copper ball valves?: Copper ball valve features:1, suitable for regular operation, quick and easy to open and close.2, fluid resistance is small.3, simple structure, relatively small size, light weight, easy maintenance.

Q:A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve: Four is 1/2=DN15, 21mm data is not accurate, if it is metric thread, provide tooth pitch and thread diameter.

Q:What is the difference between floating and fixed ball valves?: Floating ball valve ball is floating in the medium under pressure, the ball can have a certain displacement along the center axis and pressed in the export side of the seat ring, to ensure that the export side seal and the inlet end cannot seal, the floating ball valve is a single force seal form.

Q:What is the diameter of the 2 inch ball valve?: It depends on whether your ball valve is full diameter or necking

Q:DN15 ball valve with a bit of outer wire: We normally say 4 points, 6 points, 1 inches, corresponding to 152025

Q:PP-R double joint hot melt copper ball valve DN50 connection method how to connect?: There are two kinds of adjustable temperature control and fixed temperature control. The specifications are the same as those of the tube. It can be controlled by temperature control. It can be used in other material pipes. Such as: PE, PP and so on.

Q:Ball valve use?: Ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and play a decisive role in the national economy.

Q:What does one inch of an ice ball refer to?: An inch refers to the valve's medium channel is%%C25mm

Q:What does "all pass" ball valve mean?: Simply put, from the valve side of the runner hole, put a ball of the same diameter can pass to the other side, that is, all pass ball valve
