Trunnion Ball Valve Side Entry Split Body – High temperature
Trunnion Ball Valve Side Entry Split Body – High temperature have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction. Line pressure compresses the seat against the ball, the contact between surfaces generates the valve sealing. Trunnion standard construction ensures automatic cavity relief in case of overpressure in body cavity. These valves can be selected for a wide range of applications with no specific limits to sizes, pressure and temperature range. Construction: Two or Three piece bolted body;
Port: Reduced bore, full bore or fully piggable; Sealing: Bi-directional, Double block & bleed (DBB) with sealing in both directions (DIB-1&2 upon request;
Metal seated with Tungsten or Chrome Carbide coatings;
Primary metal secondary soft (PMSS) with differential hardness between the ball and seat to prevent galling of the substrate;
Soft seated with thermoplastic polymers (Nylon, PEEK, PCTFE), special polymers upon request;
Elastomers FKM, HNBR, EPDM O-Rings, special elastomers upon request
