What kind of pressure reducing valve is suitable for DN200? How about adjustable?

Look at your problem, it is estimated that the water pipeline, the water pressure reducing valve generally uses 200X adjustable pressure reducing valve and YB43X fixed ratio pressure reducing valve, 200X adjustable pressure reducing valve has a wide adjustable pressure range (can be as close as possible to the actual optimal use pressure) Large flow rate, easy to maintain (dismantling the valve cover can be repaired and there is a possibility of replacing parts to restore the function), but the pipeline exhaust is not good, the pipeline arrangement is irregular, and the installation orientation is not good (such as vertical installation) is easy to cause 200X vibration and noise during work, The water flow of the fixed ratio type is smooth, and the noise is very low, but the flow rate is generally small, the pressure can not be adjusted, and the maintenance is generally replaced as a whole. If necessary, we will be happy to work with you to suit your situation.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Depending on the medium you are using, gentleness, differential pressure and other parameters.

The main types of pressure reducing valves are:

0232 piston type pressure reducing valve model, brass nickel plated, PN16, outlet pressure can be adjusted arbitrarily, the smallest and most cost-effective imported pressure reducing valve model, can be connected to pressure gauge, widely used in high-rise buildings branch pipe decompression;

0234 piston type pressure reducing valve model, brass material, with double slipknot head, easy to install, PN25, outlet pressure can be adjusted arbitrarily, can be connected to pressure gauge, widely used in high-rise buildings branch pipe and main pipe pressure reduction;

0226 diaphragm type pressure reducing valve model, brass material, PN25, outlet pressure can be adjusted arbitrarily, can be connected to pressure gauge, widely used in high-rise buildings branch pipe and main pipe pressure reduction;

0204 diaphragm type pressure reducing valve model, brass material, PN40, outlet pressure 1-7bar can be arbitrarily adjusted, can be connected to pressure gauge, widely used in high-rise buildings branch pipe and main pipe pressure reduction;

0204 diaphragm type ultra-low pressure pressure reducing valve model, brass material, PN10, outlet pressure 0-1bar arbitrarily adjustable, can be connected to pressure gauge, widely used in precision equipment, breeding room, laboratory;

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjusting it, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can change, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve is kept constant within a certain error range.

What are the typical types of pressure reducing valves? As follows:

0232 piston type pressure reducing valve model, brass nickel plated, PN16, outlet pressure can be adjusted arbitrarily, the smallest and most cost-effective imported pressure reducing valve model, can be connected to pressure gauge, widely used in high-rise buildings branch pipe decompression;

0234 piston type pressure reducing valve model, brass material, with double slipknot head, easy to install, PN25, outlet pressure can be adjusted arbitrarily, can be connected to pressure gauge, widely used in high-rise buildings branch pipe and main pipe pressure reduction;

0226 diaphragm type pressure reducing valve model, brass material, PN25, outlet pressure can be adjusted arbitrarily, can be connected to pressure gauge, widely used in high-rise buildings branch pipe and main pipe pressure reduction;

0204 diaphragm type pressure reducing valve model, brass material, PN40, outlet pressure 1-7bar can be arbitrarily adjusted, can be connected to pressure gauge, widely used in high-rise buildings branch pipe and main pipe pressure reduction;

0204 diaphragm type ultra-low pressure pressure reducing valve model, brass material, PN10, outlet pressure 0-1bar arbitrarily adjustable, can be connected to pressure gauge, widely used in precision equipment, breeding room, laboratory;

It is used for pipeline depressurization, and protects the water used for life and production in the case of local high pressure or sudden water pressure.

Water supply for high-rise buildings, solar water heaters, water supply systems, equipment support, etc.

Piston and diaphragm valve models:

200X Pilot Diaphragm Type BAI Pressure Reducing Valve, Adjust DU Pilot Valve, Increase or Decrease ZHI Main Valve Cavity Outlet Flow, Control.

DAO valve port opening to adjust the lower inflow pressure.

1. Close the upstream containance isolation valve, open the downstream isolation valve to relieve pressure, and close the downstream isolation valve after the downstream pressure is reduced below.

2. Tighten the adjusting screw of the pilot valve to the topmost position.

3. Slowly turn on the upstream isolation to full opening.

4. Slowly tighten the adjusting screw downward, and the outlet pressure will gradually increase until the adjusting screw is locked when the setting value is set.

5. If the pressure adjustment is excessive, it must be re-adjusted from the first step, and the low pressure can only be adjusted to the high pressure.

When the valve feeds water from the inlet end, the water flows through the needle valve into the main valve control room, and the outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the spring set value of the pilot valve, the pilot valve is closed. The control room stops draining, at this time the main valve controls the pressure in the room to rise and closes the main valve, and the outlet pressure no longer rises.

When the outlet pressure of the valve drops to the set pressure of the pilot valve spring, the pilot valve opens and the control room drains downstream. Since the pilot valve system discharges more water than the needle valve, the pressure in the main valve control room drops. The inlet pressure opens the main valve.

In the steady state, the water inlet and drainage of the control room are the same, the opening of the main valve is unchanged, and the outlet pressure is stable.

The outlet pressure can be set by adjusting the pilot valve spring.

The ZJY46H combined pressure reducing valve of Beijing Times Zhongji has a maximum pressure reduction ratio of 12:1The maximum diameter can be produced up to DN1200; It is estimated that only the domestic manufacturers who can do this parameter We have used their products, and the quality is really good

Their ** is 4000231423

What you are talking about is the 200p adjustable pressure reducing valve, Shanghai Guardian valve has this kind of valve, the quality can also be, mainly for the slippery can be used in the rubber regulating pressure reducing valve to install a filter, and should be convenient for sewage requirements.
