WESDOM could provide various butterfly valves which can be widely applied in all many kind of industrial fluids. The sizes from DN25~DN2400 are all available. The standard we can comply DIN, JIS, GB, API 609, etc. CHOOSE WESOM, CHOOSE QUALITY!
This butterfly valve is a lug type valve with through holes and can be used for many applications. The through holes makes it easy to install or uninstall the valve from the pipeline. The valve can be used as a stopper, a tap for discharging at the end of the pipeline, open/close and flow control. The threaded holes make it easy to install or uninstall from the pipeline. Operation can be manual, pneumatic, hydraulic or electric.

Lug Type ductile iron butterfly valve Standard:
(1)Design and Manufacture Conform to EN 593, API609, JIS
(2)Flange dimensions Conform to EN 1092-2 PN10, PN16, JIS5K, JIS10K,ANSI B16.1,DIN2501,BS4504
(3)Face to Face dimensions Conform to EN558 series
(4)Top Flange dimensions Conform to ISO5211
(5)Testing Conform to API598、EN12266-1
Lug type butterfly valve Standard Test :
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.
