Three Piece Split Body and Cap, Soft Seated, Steel Ball Valves.
Successfully Fire-tested.

Trunnion mounted side entry steel ball valves are designed to meet API 6D / ISO 14313 and other referential international valve design standards, used for petroleum, petrochemical, oil, gas and any industrials.

Design Features Structure : 3 pieces bolted body and cap High shut-off sealing mechanism and low torque operation Block and bleed function Self cavity pressure relief Fire safe design Blow out proof stem construction Anti static design Locking device (for lever handle operation) ISO 5211 actuator mounting Emergency grease injection (option) PN design can be available

The pressure-temperature rating of soft seated ball valve are determined, not only by the valve shell materials, but also by the sealing materials used for ball seat, gland packings, O-rings, flange gaskets and bearings. Sealing materials may be high molecule, or rubber, but the choice is limited by characteristics of the service fluid, working pressures, fluid velocity, and operational frequency of the valve. As it is very difficult to predetermine the exact pressure-temperature ratings for all kinds of fluid under all imaginable conditions, general rating charts have been provided for non-shock fluid service below, based on KITZ past experiences both in the field and in KITZ laboratory. Frequent need of maintenance is another factor to be kept in mind, if very high temperature operation is planned or expected.
