Find Verified Relief Valves High Load High Impact Resistance Suppliers, Manufacturers and Wholesalers

Jone is a hydraulic customer from the United States. His company has recently developed a hydraulic relief valve suitable for machines with high impact and high load. Because of the high requirements of working conditions, the steel used for the hydraulic relief valve has not been approved yet. They have been testing in the local hydraulic relief valve manufacturers in the United States for several weeks. Due to the high cost of proofing in the United States, they want to turn to Chinese hydraulic relief valve manufacturers for sampling and testing.

Jone compared more than 10 hydraulic relief valve manufacturers and selected 3 to make samples. After receiving and testing the samples of hydraulic relief valves, none of them can meet the requirements of service conditions, and the test results are much worse than those of local manufacturers in the United States. Although these 3 hydraulic relief valve manufacturers changed the materials and improved the parameters, the toughness and plasticity of the steel still did not meet the working conditions, and Jone and his team were at a loss what to do.

His friend Tom recommended him to contact AAK hydraulic valve for a try. Jone sent us an email with a try attitude. According to his hydraulic relief valve drawings and the working conditions with large impact force and high load, our engineers were not 100% sure, but were 90% sure, giving 2-3 weeks.

Two weeks later, AAK successfully sent 6 hydraulic relief valve samples. On the 3rd day after Jone received the hydraulic relief valve samples, we received an email that the samples of hydraulic relief valve passed the performance test. AAK spent 2 weeks to try over 10 kinds of steels, and finally determined to replace 40Cr with 35CrMo steel. The high toughness and plasticity parameters of 35CrMo well match the working conditions of this hydraulic relief valve. At the same time, 35CrMo has high static strength, impact toughness and high fatigue limit, and the long-term working temperature can reach 500 . Jone was surprised that the samples of more than 10 hydraulic relief valve manufacturers in China were not successful. Even if the local manufacturers in the United States spent 4 weeks but still failed, how can AAK succeed in 2 weeks one time?

The reason why AAK hydraulic relief valves can do what the domestic factories in the United States failed to do, because:

1. AAK has full-time material engineer who is specially responsible for material screening, comparison, testing and docking with the materials research institute.

2. Good materials also need good processing. The heat treatment method adopted by AAK for 35CrMo alloy steel is 845 annealing, 860 quenching (oil quenching) and 200 low-temperature tempering. After this special heat treatment, its hardness and wear resistance are increased by at least 50%.

ROSE PEARLS is a GMO-free, natural product made of high-quality organic Rose Damascena oil from Bulgaria.

Rose Damascena, also known to the world as the Oil giving Rose from Kazanlak, is the queen of flowers and the Rose valley in Bulgaria has become her kingdom. Our rose plantations are located in to the village of Skobelevo - in the heart of Bulgaria, an ecologically clean area at the foot of the Balkan Mountains. In order to extract the essential ingredients of roses, our company Alba Grups uses water-steam technology, a technology with tradition in distillation. We use no chemicals in our process.

Hundreds of rose petals are needed to extract just one drop of rose oil. For a kilogram of rose oil we need about 4 tons of rose petals, nearly 1,660,000 freshly picked roses. Rose flowers are handpicked very early in the morning and are processed as fast as possible to keep the high quality of the oil. This makes it one of the most expensive essential oils in the world. Its quality, how it is used, and the way it benefits the body have been known to the world for centuries.

Rose Pearls capsules are a food supplement and benefit the digestive and urinary system. They help strengthen and bring the bodies systems into harmony, including the respiratory, reproductive and immune systems. Only three pearls a day will make you feel healthy, alive and energetic.

The high quality bulgarian rose oil gained its producers scores of medals and diplomas from many exhibitions and fairs.

The rose valley in bulgaria, near the town of kazanlak, is among the major producers of attar of roses in the world.
Thanks to the specific geographic and climate conditions favorable temperatures during february, when blossoming buds formed, the maroon forest soils and frequency of the rainfalls during the rose picking in may and june, more than 3 centuries had been cultivated the famous all over the world bulgarian oil rose. This rose is used for producing the incomparable bulgarian rose attar.

Salvia essential oil ( or sage essential oil) is great for relieving grief and quickening the senses, while stimulating the lymphatic system and helping with female problems, such as sterility and menopausal problems and on the skin it not only helps healing but also to reduce pore size.
Oil properties
Salvia oil has a sharp, herbal smell, and is watery in viscosity.
Origin of salvia oil
It is an evergreen perennial herb that can grow up to about 60cm ( 2 feet) high with a woody base, soft grey-green oval leaves and a mass of blue or violet flowers. The Chinese believed that it cured sterility, while the romans believed it cured just about everything.

Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is
malleable at 100 to 150°C. It is a reasonable conductor of electricity, and burns in air
at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc
on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.

We offer a wide plethora of bluish-white lustrous metal Zinc. It is brittle at ambient temperatures but is malleable at 100 to 150C. Being a good conductor of electricity it has a wide usage in numerous applications. We offer this high quality Zinc to our clients at very economical price.

Bitumen

Product Description :
Bitumen is widely used in the construction of asphalt roads and bituminous membrane products. Bitumen is commonly used to build highways, motorways and rail networks. Bitumen has excellent water-proofing properties and is widely used for making roofing products along with a range of other household and industrial applications, from emulsion paints to sound-proofing. Penetration Bitumen and Bitumen Emulsions are used for the construction of railway tracks and by using special types of bitumen such as Polymer Modified Bitumen, the vibration and noise levels are reduced due to a dampening effect. Bitumen has been proven to be effective on both high-speed railway tracks and heavy load railway tracks. Bitumen is also used for surfacing airfield runways and air strips (PMB is preffered due to its fuel resistant properties) and taxi ways. For the Marine construction industry bitumen is used for hydraulic applications such as canal lining, underwater tunnels, river bank protection, dam construction and sea defences. There are also numerous industrial applications like roofing felt material, printing inks, packaging paper, linoleum, electrical cable / Junction box insulation, mastic for roofing of terraces, and duplex paper manufacture.
