High tech double block and bleed valves (VDCI), with two independent plugs meeting stringent use criteria.

Fitted with:

• 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.
