Valve Features:
| - An extra-thick body of the actuator and the valve, ensuring a good resistance to mechanical and |
| thermal distortions |
| - Possibility to actuate the two plugs independently and to clean the chamber area, plugs closed, |
| because of double-wall leak detection channel. |
| - Partial balancing of the pressure under the lower plug with counterbalanced piston |
| - PFA seals ensure a complete sealing at high temperature and a good resistance to aggressive |
| products |
| - The design of the VDCI allows the releasing pressure to atmosphere without any risk of mixing |
| between the two ports of the valve, in case of pressure surges in excess of 150 PSI under the |
| lower ring |
| - Optional O ring seals for non-leaking during atmospheric break |
| - PMO version available |
