Knife gate valve is Bi-directional, Zero Leakage, withstanding high differential pressure and full bore Valve with minimal seat cavity for maximun flow capactiy.2. No groove is designed on the valve seat, which prevents accumulating media on the sealing surface. And thus avoids sealing surface leakage or disc blockage caused by media accumulation.3. The integrated body structure with precision casing.4. U-shaped resilient seat is embeded into the body and is well-connected with the gate, and the friction force is reduced during the upard and downward movements of the gate. This greatly prolongs the using life of the seat and realizes bi-directional sealing.5.The rubber O-ring is embeded into the flange groove ,which makes it convenient to connect the valve to pipe and provides reliable sealing6. knife gate valve is widely used in urban sewage treatment, paper-making, mine slag discharge and the fields alikeTechnical Parameter:Size: DN50~DN1200 ( NPS 2~NPS 48 ):Pressure Rating: 0.6 Mpa, 1.0 Mpa, 1.6 Mpa, 2.5 Mpa, Class 150TestingTesting includes a body shell test, a seat test and a cycling test to insure proper functioning of moving parts.Standard Shell test: Hydro test at 1.5 times the rated CWP (cold working pressure) Zero allowable leakageStandard Resilient Seat test: Hydro test at 15 psi (1 bar) and rated CWPMax. operating pressures for GAOCHUANG type PZ43 Knife Gate Valves:DN050-DN250: 10 barDN300-DN400: 6 barDN450: 5 barDN500-DN600: 4 barDN700-DN1200:2 bar
