Zimmermann & JansenMain Advantages of the

Double Disc Through Conduit Gate ValveMain Advantages of the

Double Disc Through Conduit Gate Valve• Real double block and purge

performance within one valve bodydue to 2 independent discs.

• Active mechanical seatingforce due to centralsplit-wedge-ball arrangement.

• Corrosion and wear resistant hard facing overlay on the seats; noadjustment and replacement ofseats required.

• No deposits of solid particles in valve body due to goggle type valvegate guided between guide plates.

• All internals removable throughbonnets.

• The sealing surfaces are com-pletely covered in each gate end position. Depositing within the valve and on the seats is avoided.

• Open goggle plate part equipped with tube to provide throughway.

• Purge steam connections for continuous valve body and seatpurge.

Final Considerations – Advatages and BenefitsSafety - during deheading and unheading no personnel

are required on deck due to fully remote operation.

- Real double block and purge - two independent discs.

Reliability - well proven valve design used in other severeservices such as ethylene, FCCU, phosgene, etc.

Cost reduction - low maintenance cost

- cycle time reduction
