American standard gate valve

Zui big valve wholesale base in Henan area

Characteristics
1 Product design and manufacture in line with the American National Standard ANSI B16.34, American Petroleum Institute standards AP16D and API600 requirements.
2 compact structure, small size, good rigidity, safe and reliable sealing.
3 The closing piece (shutter) adopts an elastic structure, which can automatically compensate the deformation of the valve body due to abnormal load or temperature during operation. Therefore, the seal is reliable and does not create a gate wedge.
4 Manual valves with a nominal diameter greater than or equal to NPS1011, a pressure class of 400 lbs and a nominal diameter greater than or equal to NPSS611 and a pressure rating of 600 to 2500 lbs. The operating device is equipped with rolling bearings for easy opening and closing.
5 The material of the main material, the inner material, the packing, the gasket and the fastener can be reasonably combined according to the requirements of the user or the actual working conditions.
6The valve seat can be a more sturdy valve seat, which can be matched with the material of the closing sealing surface in any combination to meet the working conditions and prolong the service life.

Antibiotic: A drug used to treat bacterial infections. Antibiotics have no effect on viral infections. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics, usually chemically related to natural antibiotics, have since been produced that accomplish comparable tasks.


Antimicrobial: A drug used to treat a microbial infection(antibiotic drugs).

"Antimicrobial" is a general term that refers to a group of drugs that includes antibiotics, antifungals, antiprotozoals, and antivirals.
