D71N non-pin nylon plate butterfly valve design standard:

Construction length implemented: GB/ t12221-1989.din3202-1999.standard.Connection flanges comply with GB, DIN, ANSI, JIS, BS standards.The test and inspection shall be conducted in accordance with GB/ t13927-92 "general valve pressure test" and API598 standard.

D71N overview:

1. The use of nylon no pin butterfly plate, with excellent wear reduction, self-lubrication, operating torque than ordinary pin butterfly valve reduced by 40 percent.

2. Good wear resistance of sealing surface (nylon wear resistance is seven times of copper), can significantly extend the service life of butterfly valve, compared with the ordinary center line butterfly valve, service life can be significantly extended by three times.

3. Nylon material has no toxicity, and antibacterial, anti-mold, in line with people's increasing attention to the requirements of green environmental protection.

4. Nylon has excellent alkali and salt resistance, weak acid resistance, inert to organic compounds, wide range of adaptation.

5. Advanced non-pin connection ensures complete isolation between medium and metal, improves product reliability, makes butterfly valve maintenance simple and easy to repair, saving time and labor.

6. The product price is much lower than the price of stainless steel valve, which can significantly reduce the project cost.

7. The connection size of the product and pipeline flange shall meet the standards of various countries for existing butterfly valve products

Nylon coating can prevent the growth of fungi, and at the same time resist corrosion can withstand 2000 hours of salt spray test, 10 years of seawater immersion test, and at the same time can prevent the exposure and impact of ultraviolet rays, and has a small coefficient of friction.
