Key Features

Fail safe isolation as the weight of the disc will always close the ITV when not being held open by the operator.
Self-seating disc designs provide perfect seating regardless of minor misalignments.
All SS construction and PTFE-coated rotating joints surface provide full compatibility with cryogenic temperatures.
Eliminates damaging up-loads on the tank bottom by limiting the force from the open and close operators.
Redundant opening cables provided to allow manual operation if necessary.
Pressure equalizing pilot valve integral with the valve disc.
Anti-vortex vanes counter the Coriolis effect, preventing lowered pressure and resulting product gasification during withdrawal.
Explosion-proof position indication limit switch (NEMA Type 7, Class 1, Groups C and D) mounted on the open operator available as an option.
Auxiliary close cables augment normal sealing forces and improve the system’s manageability.
Control panel option includes all components in a single weather-tight enclosure designed for roof installation and remote operation.
