trunnion & floating ball valves | Floating Ball Valve Side Entry Modular Body (DBB) Valves suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining including system isolation, pressure level and flow measurement, instrument drain, chemical injection and sampling for smaller sizes. STANDARD FEATURES! Sealing Bi-directional VDA: Metal seated (Tungsten /Chrome Carbide coatings) VDB: Soft seated with thermoplastic polymers (RPTFE, Nylon, PEEK, PCTFE), special polymers upon request PTFE Lip seals and Elastomers FKM, HNBR, EPDM O-Rings, special elastomers upon request VD2: Soft seated with thermoplastic polymers (RPTFE, Nylon, PEEK, PCTFE), special polymers upon request Elastomers FKM, HNBR, EPDM O-Rings, special elastomers upon request GENERAL CONSTRUCTION Floating ball valves have the obturator free from axial constraints and it is supported between two soft seat inserts; under pressure the ball compresses the downstream soft insert to obtain the sealing; these valves are generally recommended for use in clean service with limited sizes and ratings. Erreesse production range offers a wide selection of models and construction suitable for critical services also. Erreesse modular double block & bleed (DBB) valves are engineered and manufactured to provide a compact and reliable alternative to multiple instrument valve systems, reducing leak paths and saving installations and maintenance costs.
