API Swing check valve Structure and distinguishing feature
1. The selection is elegant, tallies domestic, outside is related the standard, the material comprehensive quality is high.
2 Seals the vice-pair advanced reasonable, the valve petal, the valve seat packing surface use the iron-base alloy or the department too vertical (Satellite) cobalt base hard alloy built-up welding surface become, wear-resisting, thermos table, anti-corrosive, the anti-abrasion performance is good, the service life is long
3 standard design: According to ANSI B16.34.
4 May use each kind of tubing flange standard and the flange seal pattern, satisfies each kind of project to need and the user request.
