This reducing valve the new type pilot extra-huge membrane pressure reducing valve developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.
Pressure rating: 1.6- 2.5mpa
Specification : dn15-50
Material:steel wcb
Standard flanges :din ansi jis jb79.

Guar gum is a fiber from the seed of the guar plant.
Guar gum is used as a laxative. It is also used for treating diarrhea, irritable bowel syndrome (IBS), obesity, and diabetes; for reducing cholesterol; and for preventing “hardening of the arteries” (atherosclerosis).
In foods and beverages, guar gum is used as a thickening, stabilizing, suspending, and binding agent.
In manufacturing, guar gum is used as a binding agent in tablets, and as a thickening agent in lotions and creams.
How does it work?
Guar gum is a fiber that normalizes the moisture content of the stool, absorbing excess liquid in diarrhea, and softening the stool in constipation. It also might help decrease the amount of cholesterol and glucose that is absorbed in the stomach and intestines.
There is some interest in using guar gum for weight loss because it expands in the intestine, causing a sense of fullness. This may decrease appetite.
USES:
Diarrhea. Adding guar gum to the tube feeding formula given to critical care patients may shorten episodes of diarrhea from about 30 days to about 8 days.
High cholesterol. Taking guar gum seems to lower cholesterol levels in people with high cholesterol. Guar gum and pectin, taken with small amounts of insoluble fiber, also lower total and “bad” low-density lipoprotein (LDL) cholesterol, but don't affect “good” high-density lipoprotein (HDL) cholesterol or other blood fats called triglycerides.
Diabetes. Taking guar gum with meals seems to lower blood sugar after meals in people with diabetes. By slowing stomach emptying, guar gum may also lessen after-meal drops in blood pressure that occur frequently in people with diabetes.
Constipation.
Irritable bowel syndrome (IBS).
mainly responsible for the purchasing of hydraulic pump components. Last October, developed a new hydraulic pump and planned to promote this new product at this year's exhibition. During the debugging, the output pressure of the hydraulic pump can not be established several times, which is a little troublesome, because the owner has sent all the invitations to the exhibition to the customers and grandly introduced the functions of this hydraulic pump. The R & D personnel checked and tested each component one by one. It is basically certain that it is caused by the instability of the pilot operated pressure control valve.
The technical team dissected the pilot pressure control valve and found local friction marks on one side of the hole wall of the valve body. The diagnosis conclusion is that the main valve spool is stuck, which should be caused by the concentricity difference between the hole of the main valve body and the hole of the pilot pressure control valve body. to re purchase the pilot pressure control valve that meets the technical requirements, which must be solved within 25 days, otherwise he will leave because the exhibition is too important. the original hydraulic valve manufacturer and got a reply that due to equipment, he could not produce high-precision pilot pressure control valves with the exactly same concentricity. At the same time, he contacted a number of hydraulic valve suppliers and they basically replied that they could not do such a high precision pilot operated pressure control valve, which made almost .
When searched the hydraulic valve suppliers in , he found AAK HYDRAULIC VALVE. The details page of the hydraulic valve on AAK made feel that maybe AAK could have a try. He emailed us firstly to ask whether the concentricity of the pilot operated pressure control valve could be consistent. We need the detailed drawings, working conditions and parameters of his whole hydraulic pump to judge. After receiving all information from him, AAK technical team pondered the whole afternoon, with more than 95 confidence, and it would take 15 20 days to complete it.
he was happy and uneasy. He was happy that some hydraulic valve manufacturer could try this high-precision pilot operated pressure control valve and has a high probability of success. He was uneasy that if AAK HYDRAULIC VALVE did not succeed in proofing, the time would be wasted. We understand his concern. We told him that the reason why we are not sure for 100 is that there is a data that can't be determined. If AAK HYDRAULIC VALVE failed in sampling, then he should not waste time in Ningbo area. We suggest that he also find a hydraulic valve supplier in Europe, so as to sample with AAK at the same time.
