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 […]
Trunnion Side Entry Valve
Trunnion side entry ball valve is the most popular ball valve design for Oil & Gas application. The ball is held on a fixed vertical axis and is free to rotate about it. Sealing is assured by pressure & spring energized seats. The body can be 2 or 3 bolted pieces. For small sizes, the […]
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 […]
SPM-D10 Series
vThe SPM-D10 Series are microprocessor-based synchronizers designed for use on three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D10 Series synchronizers provide automatic frequency, phase, and voltage matching, using either analog or discrete output bias signals.
The SPM-D11
The SPM-D11 Series are microprocessor-based synchronizers designed for use on one- or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D11 Series synchronizers provide automatic frequency, phase, and voltage matching, using either analog or discrete output bias signals. It combines synchronizing for one circuit breaker, load and […]
SPM-D21 Series
The SPM-D21 Series consists of microprocessor-based synchronizers designed for use on three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D21 Series provides automatic frequency, phase and voltage matching using either analog or discrete output signals. It combines synchronizing for a GCB (generator circuit breaker) and a MCB […]
