Q:PPR ball valve diameter is 3 cm, what is the specifications?: Closer to the national standard, the size should be 32 (phi 32)

Q:For the master enlighten Q47 ball seat spring hole number is determined by how: Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameterCalculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).

Q:Ball valve 11F, 41F, 11H, 41H: 41H flanged ball valve type through the use of alloy steel seal. In addition there is a complete expression of Q words, there are nominal pressure such as Q11F-16 Q41F-16

Q:Stainless steel ball valve Q41F-16P DN80 weight is: The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers

Q:Role of ball valve DN20-Q11F-16: Q11F ball valve is to control the circulation and cut-off of the pipeline medium.

Q:Must I use the ball valve for the heater?: Valve main points and angle valve, ball valve in the water pressure is large enough to use, angle valve can increase the pressure of a little water.

Q:What's the difference between a copper ball valve and a stainless steel ball valve?: 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

Q:It's the brass valve in front of the water meter. It doesn't move at all. It's broken. Found the following axis of rotation is not rust, copper plated iron, with a screwdriver to the ball screw, screw is not moving, the valve is much worse than PPR. Real junk products: What caliber, faucet is generally small caliber ball valve, can be replaced directly, if it is large, high cost words. Repair may be considered. Generally two problems: 1, stem wear or exercise, can not transfer to the ball core, you need to replace the ball valve; 2, the core of the groove long time work under the edge of wear and tear, slipping, you can replace the ball core;

Q:What is the difference between ball valve and plug valve?: Plug valves are closed or plunger shaped rotary valve, through the rotation of 90 degrees to make the valve plug on the mouth of the channel with the valve on the mouth of the same or separated, to achieve a valve opening or closing. Plug valve plug shape can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the tapered valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve lighter, but at the same time a certain loss. Plug valves are most suitable for cutting and turning on the medium and for shunting applications, but in accordance with the applicable nature and sealing surface erosion resistance, sometimes also used for throttling. As the plug seal between the movement with a wipe action, while fully open, you can completely prevent the contact with the flow medium, it is usually also used for suspension with particles of media. Another important feature of the plug valve, it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valve used, and some connecting fittings needed in the equipment.Plug valves use:Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, liquefied petroleum gas, HVAC and general industries.
