Semi-lug butterfly valve can be ether mounted between two pipes by ordinay hexagon head bolts or mounted on the pipe end (lugged-type).Easy to installation.
4 inch butterfly valve used EPDM/NBR rubber seat, which can ensure the tightness of the valve, o leakage.
Semi lug type butterfly valve can equiped by lever handle,worm gear box, electric actuators, pneumatic actuators, hydraulic actuators accoring to customers's requirements. All the actuators can easy to exchange.
4 Inch Semi-Lug Water Medium Butterfly Valve
1. DN50(2")-600(24") Type "LT" semi-lug butterfly valve are suitable for the pressure grades of PN10 MPa and PN16 MPa separately. Two dimensions in one column how two connection dimensions of PN1. 0/PN16MPa pressure grade. For the connection dimensions of pipe fanges mounted to the valve. Please refer to the connection dimensons of flanges table. The upper flanges of the butterfly valves accommodates all types of operaters: manual, wormgear, electric and pniumatic actuators.
2. Difference between Type " A"and"LT": Both Type"A"and"LT" have the same constructi on and perform ances and are made of the same materials. The main difference between them is that type"A"valves are mounted between pipe flanges (wafer type) by bolts (or extended hexagon-head bolts), while type" LT" can be ether mounted between two pipes by ordinay hexagon head bolts or mounted on the pipe end (lugged-type). As the valve is used at the end of pipe line. itis necessary to indicate.
1. The semi lug butterfly valve has samll torque when operating the disc to open or close by lever handle or worm gear, it is very easy to operate.
2. The 4 inch butterfly valve face to face is like wafer butterfly valve, shortly and save space when installation on the pipeline.
