FO1-BV1LT-3P(Lugged type Butterfly Valve–Pneumatic Actuator)
●Brief
The butterfly plate has automatic alignment, which realizes the small interference fit between the butterfly plate and the valve seat. Phenolic back seat has the characteristics of no falling off, tensile, leak proof and convenient replacement. Due to the seat sealing surface and the back, As a result, the deformation of the valve seat is reduced.
●Features
1. The valve rod seal is not easy to deform, so as to avoid the usual valve stem leakage phenomenon. The overall support is good, stable and firm.
2. It is easy to control the torque value in a proper range. It is easy to use two section stem without pin connection. The structure is simple and compact, and the disassembly is very convenient.
APPLICATION
General Use: Water,sea water,gas, pressurized air, acids etc.
