When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!: Switching type (one on and off)Block digital display with the upper and lower limit control valve opening and closing is goodProbably more than 100Regulating type (to keep temperature at a constant value)With PID valve position regulator can be very good controlAbout 300 more

Q: How to suppress the valve?: Upstairs is right... But look at the situation, there are some valve flange is 16 pressure, but the body can only play 10 pressure, there are cases.. Such as knives, valves and other ventilation valve

Q: What does "1/2" mean on the valve?: Indicates that the ends of the valve are 1/2 inches in diameter. 1 inches is converted to metric system of 25.4 millimeters.

Q: Is the heat jacketed valve fitted with flanged flanges?: Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.

Q: How big valves are used in the DN90 pipeline?: If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding

Q: What are the types of valves?: 1.2.3 classification by body materialx09 (1) non-metallic material valves: such as ceramic valves, glass fiber reinforced plastic valves, plastic valvesx09 (2) metal valves: such as copper alloy valves, Aluminum Alloy valves, lead alloy valves, titanium valves, Monel alloy valves, cast iron valves, carbon steel valves, cast steel valves, low-alloy steel valves, high alloy steel valves.x09 (3) metal body lining valve: such as lining lead valve, lining plastic valve and lining enamel valveHa ha, I answered it only a while ago

Q: What are the ten major brands of China's valves?: In the fluid piping system, the valve is the control element, its main function is to isolate the equipment and the piping system, regulates the flow, prevents the backflow, the adjustment and the excretion pressure. As the piping system selects the most suitable valve, it is important to understand the characteristics of the valve and the steps and the basis for selecting the valve.
