Description
FFV make Diaphragm Control Valve with Electro Pneumatic Positioner.Diaphragm Control valves Pneumatic Actuators can be either
(a)Air to Open or(b)Air to Close.Designed is such that if the air supply fails, the control valve will be either fully open, or fully closed, depending upon the safety requirement of the process.
On-off type or modulating type FFV make control valves are widely used for machinery, and plant engineering for steam controlling lines,thermic fluid lines,various liquid lines,heat exchanger,pumps pipes lines & gases.
Features
- FFV Control Valves are Design for high temperature lines
- Powerful thrust at high response speed
- Low friction in performance / Low overall height
- High reliability due to few moving parts in an assembly
- Suitability for installation various accessories can be used as manual override,Electro pneumatic positioners,Airfilter, regulator,lubricator
