GVPC Valve
GVPC Valves plays a very important role in the automatic control of installations which depend on the distribution and the correct amount of liquids or gases flow control.
GVLN Valve
GVCH Valves plays a very important role in the automatic control of installations which depend on the distribution and the correct amount of liquids or gases flow control.
SUBSEA VALVES
Della Foglia is one of the first worldwide companies to reachAPI 6DSS qualification for subsea pipeline ball valves. Thisproves the capability of Della Foglia to manufacture suchcritical products.Special design is developed for each application in orderto guarantee the required performance level for the wholepredicted life of the valve.A high level quality control inspection& test, as […]
TOP ENTRY VALVES
Top Entry ball valve design is characterized by one piece body construction with top access to allinternal components. Top Entry Ball Valves are the preferable solution when it is required to perform inline maintenance, and when the reduction of possible leakage path is mandatory. The body could bemanufactured from forged billet or high quality castings. […]
SIDE ENTRY API 6A VALVES
Trunnion side entry ball valve is the most popular ball valvedesign for Oil & Gas application. The ball is held on a fixedvertical axis and is free to rotate about it. Sealing is assuredby pressure & spring energized seats.The body can be 2 or 3 bolted pieces. For small sizes, theball is supported by a […]
CRYOGENIC VALVES
Seats and ball design prevents thebody cavity to go over-pressure(e.g. due to thermal shocks) byan automatic system of relievingpressure to the upstream side ofthe line (not downstream or to theatmosphere).• Low fugitive emission stempacking (certified to ISO 15848class A), adjustable or pressureenergized design• Vent and drain are provided withpad flanges c/w blind flanges toprevent leakages […]
Floating Valves
Floating ball valves have a simple structure: theball is supported by the seats but can float insidethe valve body.Under medium pressure, the ball drifts towardsthe downstream side pushing against the seatensuring sealing reliability.The range of Della Foglia Floating ball valvesincludes side entry, bolted body or threadedbody, and the special top entry design.Materials of construction are […]
FULLY WELDED VALVES
Fully welded ball valves are characterized by body fabricated bywelding of forged rings.The result is a solid assembly with no leakage paths.A fully welded application is a preferable solution when nomaintenance is scheduled on valves and when it is mandatory toavoid any external leakage.A typical application is for underground valves.Welding is performed by highly qualified […]
