Tank bot. mixpr. valve VDCI MC FdC

The VDCI MC tank bottom leak chamber valve is intended to cut off the tank from the rest of the process circuit.

Features

• Isolates the tank from the rest of the process circuit
• Body and plug shape provide the tightest seal to the tank wall, without retention area
• Same features as VDCI MC (floating seal, thick body, etc.)
• Leakage chamber washed by pulsing the lower plug
• The leak can be viewed thanks to a controlled microvalve
• Leak free opening

Materials

• Body: stainless steel 1.4404 / 316L
• Shut-off unit: stainless steel 1.4404 / 316L
• Plug seal: PFA
• Other seals: EPDM, fluorinated elastomer (FKM)
• Actuator: stainless steel 1.4301 / 304

Service conditions

• Max. temperature: +140^oC/+284^oF
• Temperature differential between the upper line and the lower line: max. +90^oC/+194^oF
• Min. temperature: -5^oC/+23^oF
• Max. working pressure permissible in the tank: 4 bar (400 kPa)/58 psi
• Max. working pressure in the valve: 7 bar (700 kPa)/102 psi
• Actuator air supply pressure: 5.5 bar to 7 bars (500 to 700 kPa)/80 to 102 psi with ACS control top. Up to 8 bars (800 kPa)/116 psi with direct supply, according to the conditions of operating
