Introduction
Wafer type check valve is available with piping of PN1.0MPa~42.0MPa (Class150LB~Class2500LB),DN15mm~1200mm (NPS1/2"~48") and working temperature of -196~540°C), using for preventing of the back flow. By selecting different materials, wafer type check valve can be applicable to water, steam, oil, nitric acid, sulfuric acid, ethylic acid and urea, etc.
