Erreesse - Model VDA–VDB–VD2 -Side Entry Modular Body Floating Ball Valve
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. 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.
