D41X handle flange butterfly valve principle role:
Butterfly valve opening and closing member is a disc-shaped butterfly plate, in the valve body rotates around its own axis, so as to achieve the purpose of opening and closing or regulation. The advantages of butterfly valve are simple structure, small size, light weight, small installation size, rapid switching.
D41X/D41F type flange butterfly valve series adopts centerline vertical plate, soft seal valve seat structure, simple structure, convenient manufacture, low price; manual butterfly valve is handle driven suitable for applying to the nominal pressure ≤ 1.6MPa, the nominal diameter is less than DN200 of a variety of water, oil, gas, and other media in the official channel.
1.Simple structure, small torque, easy and rapid operation;
2.has good flow regulation and sealing performance, air pressure test leakage is zero;
3.synthetic rubber valve seat has corrosion resistance, erosion resistance, dimensional stability, good resilience;
4.can be assembled with electric actuator and pneumatic actuator to realize remote large-scale centralized control.
