Aluminium Alloy Valve

Aluminium ball valve:
Features:
1) Material: ALUMINIUM ALLOY ( BODY AND BALL)
2) Class: 150-1500 LBS
3) Size: D15-D80
4) Standards: API6D, ANSI B16.34
5) Operator: handwheel, gear, electric actuator
6) CUSTOM FOR CLIENT¡¯S  REQUIREMENT

ALUMINIUM ALLOY connectors aluminium alloy fitting, aluminium alloy valve and ball valve are new developped aluminium alloy with mass factors based on alloy, through some technical method, such as material designing, extrusion shape, heat disposal intensification and surface anode oxidation, the new product can be provided with standard criterion, compared with brass, cast iron, the alloy have doubtless advantage and characteristic, this conclusion is acquired through a series of test on physical performance, anti-rust, and environmental protection, on above aspect, the alloy is superior to traddtional brass and cast iron making water meter parts. Moreover, the alloy can settle out second-time pollution from water drinking tap terminal. For the aluminium alloy connector ,aluminium alloy fitting and aluminium valve are used in water supply and water threatment system widely. It¡¯s cheaper more than brass.
Alunimium alloy and brass comparation as below:

1. aluminium alloy biology-chemistry test
The content of all the microelement and component, which is proved that the alloy is conformed to sanitary stardard in every aspects, so it makes none of harm to people¡¯s health.

2. comparation in environmental protection.
1, Aluminium alloy connectors, fitting, ball valve made from aluminium alloy can be able to immune to air and environmental pollution, the aluminium alloy is shaped under normal temperature and cold forge without letting exhaust gas and waste water go out. Therefore, its production leaves us a non-pollution clean working condition.
2, the forging temperature for cast iron parts is between 1300degree - 1600 degree, while copper is between 1100 - 1300 degree. Either of the two meterial forging temperature is so high that the exhaust gas and ash volatilized in the air caused environmental and ecological pollution and dirty workshop.

3. intension and ductibility test.
test target : DN15 connector, test result as below:
brass-made connector destructive pull: 28.50KN intension length: 4.1mm
Aluminium alloy-made connector destructive pull: 30.85KN intension length: 5.2mm

4. rust-resistance test result
1, a- the aluminium alloy connector show dark color when in water for 19months whose surface without being protected disposal. The parts surface dipped in water have no peels and rust.
b- brass connector surface show gray color after kept dipped in water for 19 months.
2, a- after 24 hours-salt-fog disposal to the aluminium alloy parts whose surface had been anode-oxidation disposed ,without any flaw
b- brass parts show non-obvious changes.
3, a- after dipped in 5%NACI solution for 36 hours, the 2 parts made from different materials show none of changes.
b- after dipping test, kept in air 72 hours (with surface semi-dipped),
Alloy parts show none of changes, while brass parts appear evident color change, with part light patina. (green color)
4, rust-resistance comparation under the condition of weak-acid:
a- after dipped in weak-acid solution (PH5.5-6.5) for 36 hours,
Aluminium alloy parts show none of changes. Brass parts how evident color change.
b- after dipping test, kept in air 48 hours (with surface semi-dipped),
Alloy parts show non-obvious changes, while brass parts appear serious color change, with part heavy patina. (green color)
5, rust-resistance comparation under the condition of weak-alkali:
a- after dipped in weak- alkali solution (PH7.5 -8.5) for 36 hours,
Alloy parts show non-obvious change.
Brass parts show non-obvious change.
b- after dipping test, kept in air 48 hours (with surface semi-dipped),:
Alloy parts show non-obvious changes, while brass parts appear evident color change.
Above show that the special aluminium alloy is conformed to brass parts standard and can be applied in practical filed. The index and rating result from physical- chemistry and environmental protection test is more scientific. Special aluminium alloy will be more competitive with high sealing advantage as no sand-hole come out during different production flow and technology. Meanwhile, it have all- aspect compound advantage that is overwhelmingly superior, especially after anode oxidation disposal, the alloy keeps itself a completely sealing and insulating condition so that minimize the possibility to let microelement going out, it will have a better rust-resistance and permanent safety.

The description for the aluminium alloy parts

1. material and technology
the more than 97% pure aluminium content , belongs to the type of deformed aluminium alloy cold extrusion shape tech, that formed under pressure of 200T.

2.surface preparation:
Broad functions of oxidation, including the chemical oxidation, anode oxidation, horniness oxidation, porcelain oxidation (called as ceramic alloy),which has extensive individuation surface tinting.

3.quality:
each data reach the application standard to assure high steel property and make every product without the leakage problem when using and not easy to break up under gravity.
