Description
Butterfly valves series PA200 with a lined disk and body are designed for industries with increased resistance to corrosive environments, where the temperature of the working medium does not exceed +200 °С. Valves can also be used in non-aggressive environments. 100% -PTFE coating of the flow-through part of the body and the disk completely eliminates the working medium contact with the materials of main parts. Connection type is flanged and wafer. Valves series PA200 can be used as shut-off and control valves. Upon customer's request, valves of this series can be equipped with electric, pneumatic actuators of various manufacturers, both in general industrial and in explosion-proof design. And also with a set of mating flanges and fasteners. |
