JESSRO PVC ball valves, PVC check valves, PVC single union ball valves, PVC true union ball valves, PVC butterfly valves and PVC foot valves, are using fresh original PVC and PP materials. All the valves have advanced design and scientific modeling design that can make sure the perfect performance in all sorts of using environment. All the valves have two connection mode ,socket and screw ,which one are greatly increase the use convenience . We use the original PVC materials with high quality in order to guarantee the 20 years life of the valves. We also use acid and alkali resistant ,wear resistance of high aulity EPDM to increase the service life of the valve. So our PVC valves are widely used in construction, water treatment ,swimming poor and water project in pisciculture.
Features:
1) Optional explosion proof type
We have all the size from 1/2" to 8" in a full range items and we can supply you ASTM standard, JIS standard , DIN standard, BSPT standard, CNS standard and so on.

Product classification Liquid microbial agent is a photosynthetic bacteria liquid that is inoculated with photosynthetic bacteria by organic and inorganic raw material culture solution and fermented by fermentation.
The solid microbial agent is formed by adsorbing photosynthetic bacteria liquid from a solid substance as a carrier.
The photosynthetic bacterial fertilizer produced by the application method is generally a liquid bacterial liquid, which is used for base fertilizer, top dressing, seed dressing, foliar spraying, and sputum rooting of crops.
As a seed fertilizer, it can increase the biological nitrogen fixation, improve the nitrogen fixation effect of the rhizosphere, and enhance soil fertility.
Foliar application can improve plant nutrition, enhance plant physiological functions and disease resistance, thereby increasing production and improving quality.
As a fruit and vegetable preservative, it can inhibit the diseases caused by pathogens and has a good effect on the preservation of watermelons. The main reason for photosynthesis bacteria to prevent diseases is because it has a bactericidal effect and can inhibit the growth of other harmful flora and viruses.
In addition, it has a good application prospect in animal husbandry for feed additives, deodorization of livestock and poultry manure, and disposal of organic waste.
Since the application history of photosynthetic bacteria is relatively short, many aspects of applied research are still in the initial stage, and there is still a lot of in-depth research work to be done. In particular, the foundation of this product's quality, standards and further improvement of application effects is weak and needs to be further strengthened. The current research and experiments have shown that photosynthetic bacteria as an important microbial resource, its prospects for development and application are broad, will have an irreplaceable application market, and will play an increasingly important role in human activities.

Photosynthetic bacteria fertilizer, a bacteria that can use light energy as a source of energy, collectively referred to as PhotoSynthetic Bacteria (PSB). According to whether photosynthesis produces oxygen, it can be divided into non-oxygen photosynthetic bacteria and oxygen-producing photosynthetic bacteria; and it can be divided into light energy autotrophic type and light energy heterotrophic type according to the different utilization of photosynthetic bacteria carbon source. Hydrogen sulfide is a purple sulfur bacteria and a green sulfur bacteria for photosynthesis hydrogen donors, and the latter is a purple non-sulfur bacteria with various organic substances as a hydrogen donor and a main carbon source.
