DN50~DN200 Pressure PN10 PN16 ASTM A351 Class CF8M Wafer Butterfly
Valve
Triple eccentric butterfly valve DN600 specifications
Nominal diameter: DN50 ~ 2000mm
Nominal pressure Pn (LB) : 0.6 ~ 6.4MPa
Applicable medium: air, water, steam, gas, oil and acid, alkali,
salt with weak corrosive medium, etc
Applicable temperature: carbon steel: -29℃~425℃;Stainless steel,
chrome-molybdenum steel: -40℃~550℃
Leakage rate :0.1*DNmm3/S (in line with GB//T13927-92 standard)
Actuation: handle, turbine, electric, pneumatic.Electric and
pneumatic devices adopt famous and superior products at home and
abroad, with more reliable performance (can be specified by users).
Stem can be lengthened according to user's requirements.
When the butterfly valve is used in urban heating pipe network, the
two-way pressure sealing can be selected according to the user's
demand.
Triple eccentric butterfly valve DN600 Main parts and materials
Body: carbon steel, stainless steel, chromium molybdenum steel,
alloy steel
Stem: 2Cr13, 1Cr13 stainless steel, chromium molybdenum steel
Butterfly plate: carbon steel, alloy steel, stainless steel,
chromium molybdenum steel
Bearing: austenitic stainless steel, 304 nitriding
Sealing ring: stainless steel and high temperature resistant
asbestos plate is composed of multiple layers

Body Test :1.5 times the working pressure with water. This test is
performed after valve assembly and with disc in half position open,
it is called as a body hydro test.
Seat Test :1.1 times the working pressure with water.
Function / Operation Test :At the time of final inspection, each
valve and its actuator (Flow-Control Lever / Gear / Pneumatic
Actuator), under goes a complete operating test (Open/Close). This
test carried out without pressure and at ambient temperature. It
ensures the correct operation of the valve / actuator assembly with
accessories such as solenoid valve, limit switches, air filter
regulator etc.
Special Test :On request, any other test can be carried out
according to special instruction by client.
