QC:
1) Checking the raw material after they arrived the factory
2) Checking the swatches after cutting by mould
3) Checking all the details while the production line operated
4) Checking the goods after thae are finished
5) Checking all the goods after they are packed
6) Seaworthy packing¼？ Single valve is packed with foam plastic bag.Put sponge in each floor, 1.1*1.1*0.78m exported plywood case; One 20'GP can in bule loaded on 24pcs plywood cases more or less.
Features:
1.Well-selected materials, meet with domestic and foreign standards, reasonable structure, beautiful shape.
2, Sealing surface of seat and valve flap uses iron-based alloy cladding stellite (Stellite) cobalt-based alloy cladding made of wear-resistant, high temperature resistance, corrosion resistance, anti-abrasion performance, long service life.
3, Stem has a good anti-corrosion and scratch resistance after quenching and surface nitriding treatment.
4, Can be used with a variety of flange pipe standard and sealing surface pattern to meet the various engineering needs and users' requirements.
5, Full range of body materials, packing and gasket can matched based on the actual working conditions and users' reasonable request ,applied to all kinds of pressure, temperature and medium conditions.
6, Sealed uses screw connection seal seat and body formed austenitic stainless steel welding, sealing, reliable, replacement of filler may be carried out in non-stop machine conditions, convenient and doesn't affect system operation.
