Eccentric Double Offset Design Seating

The double offset shaft/disc design ensures bi-directional sealing throughout the full pressure range of the valve. The cam-like action produced by the offset stem and disc, effectively lifts the disc off the seat during the initial opening of the valves, reducing seat wear and eliminating seat deformation at the top and bottom. When the disc is in the open position, there is no contact between the disc and seat. Operating torques are reduced and seat life is extended.

Vacuum Service

The drop tight sealing capabilities of MAX-SEAL valve are excellent for vacuum service. Soft seated standard Valves are suitable for vacuum service to 20 microns. Denote vacuum service on the order.

 

Steam Service

MAX-SEAL standard valves are ideally suited for saturated stem applications to 180°C (135psig)(RTFE seat). Carbon filled TFM seats and high temperature graphite stem packing can handle pressure up to 195°C (200psig)

 

Product Identification

Every Max-Seal Valve has a special identification tag attached to the valve body. Information includes valve figure number, the size and pressure class, the materials of construction, and the operating pressures and temperatures.

The metal tag also includes a serial number: The serial number is recorded by the DaeJung Quality Control Department along with the test results and material certification data, for individual traceability and certification of every valve produced.
