  • Valve Testing: Hydrostatic and pneumatic testing to API 6D, ASME B16.34, ISO 5208.
General Construction

Floating ball valves feature an obturator free from axial constraints, supported between two soft seat inserts. Under pressure, the ball compresses the downstream insert for sealing. Recommended for clean service with limited sizes and ratings, these valves offer a compact and reliable alternative to multiple instrument valve systems, reducing leak paths and saving on installation and maintenance costs.

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.
