1.Technical Date:

Size: DN20-DN800

Nominal Pressure: PN10/PN16/PN25

Operation Temperature: ≤80°C

Suitable Medium: Water.

2.Feature:

200 x vacuum regulator valve by the main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge of hydraulic control of system. After use, when the setting outlet pressure, stable outlet pressure automatically.

This product use pilot valve to control themselves, do not need other devices and energy sources, convenient maintenance, pressure control accuracy is high, affected by the inlet pressure and flow rate is small, reduced pressure regulator is reliable.

This series valve products are widely used in high-rise buildings, living quarters and other water supply pipe network system and urban water supply engineering.

Q: What's the valve specification DN20?: Valve specification DN20 is 6.The inches in the valve refer to inches, 1 inches =25.4mm, and 1 inches =7.62 cents.The corresponding relation between inch and DN and mm is:4 is divided into corresponding caliber DN15, that is, diameter 15mm;6 is divided into corresponding caliber DN20, that is, diameter 20mm;1 inches for the corresponding caliber DN25, that is, diameter 25mm;1.2 inches for the corresponding caliber DN32, that is, diameter 32mm;1.5 inches for the corresponding caliber DN40, that is, diameter 40mm;2 inches for the corresponding caliber DN50, that is, diameter 50mm;2.5 inches for the corresponding caliber DN65, that is, diameter 65mm;3 inches for the corresponding caliber DN80, that is, diameter 80mm;4 inches for the corresponding caliber DN100, that is, diameter 100mm;5 inches for the corresponding caliber DN125, that is, diameter 125mm;6 inches for the corresponding caliber DN150, that is, diameter 150mm;8 inches for the corresponding caliber DN200, that is, diameter 200mm;10 inches for the corresponding caliber DN250, that is, diameter 250mm.

Q: What are the valves at home?: Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.

Q: What does "TD671F" mean?: TD671F is pneumatic clamp type soft sealing butterfly valveValve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q: Who knows which kind of water valve is good?: Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.

Q: How big valves are used in the DN90 pipeline?: DN is the nominal diameter, only DN80, DN100.It is estimated that your pipe is outside diameter 89mm, that is DN80, that is to choose DN80 valve.

Q: I would like to ask commonly used water valve what kind of? What are the characteristics?: The valve is usually composed of two parts: the actuating mechanism and the valve bodyAccording to the power used by the executing agency, the valve can be divided into four kinds: manual, pneumatic, electric and hydraulic. According to its function and characteristics, it can be divided into on-off valve, regulating valve, electromagnetic valve, electronic type, intelligent type, etc.According to the type of the body: through single seat, through two seater, angular, diaphragm, three links, eccentric rotation, butterfly, sleeve type, spherical and other 10 kinds of; according to the valve body material: cast iron, cast steel, forged steel, carbon steel, stainless steel, copper, plastic valves.

Q: What do letters represent in the QF-2 and PX-32 valve models?: Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!

Q: What is the flow medium of the valve?: Valve flow medium refers to the valve through the fluid, gas and liquid.For example: water, air, oil, gas, steam, acid, alkali, gas, heat conduction oil and so on, are called medium.

Q: Which valves are installed in a directional manner?: Regulating valve, stop valve, eccentric butterfly valve, check valve, one-way valve, solenoid valve, pressure reducing valve, drain valve and drain valve. Needle core valve, V ball valve, part of the ball valve, there is flow.Few. Such as floating ball valve, the central butterfly valve does not flow requirements. In general, if the regular manufacturers of valves, flow direction will indicate the flow of medium, to get the valve can see.

Q: Is there any difference between the valve and the water valve?: There is no difference between the low pressure lubricating oil pump, as long as the excuse right on the line, not to pressure, design pressure ball valve common does not exceed 3MP, the maximum pressure of only small gear pump vane pump is 2.5MP, the other piston pump, gear pump, the pressure is above 6.3MP. Certainly not. Unless using high pressure water pipe valve.
