Product Description
Swing check valve, alloy check valve, wafer check valve, dual plate check valve

*Swing check valves is a hoist device which connects or disconnects pipeline media. It's suitable for various pressures, temperatures and medias  in medium and small diameter pipes.


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.
 
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
