Fluitek Orsenigo Valves S.r.l. products

Floating Ball Valves typical application is for smaller sizes (up to 6 inches) and lower pressure classes. They are characterized by simple design, easy maintenance, low cost and quick delivery. Body construction can be two or three pieces, bolted or screwed body, made by forging, forged or rolled bar. Wide range of materials: carbon steels, austenitic or martensitic SS, duplex-superduplex SS, nickel-based alloys, titanium, aluminium-bronze and other exotic materials. Valve main technical features include automatically self relieving body cavity (due to floating ball) and anti blow-out stem.

Trunnion Side Entry Ball Valves typical application is for gas or crude oil pipelines, larger sizes (up to 60 inches) and higher pressure classes (ASME 4500 or API 15000psi). Body construction can be two or three pieces for smaller sizes (up to 6” RB), three pieces for larges dimensions. Raw material can be either forgings or centrifugal castings. Wide range of materials: carbon steels, austenitic or martensitic SS, duplex-superduplex SS, nickel-based alloys. Bolted body as a standard, welded body for special applications (see specific section).

Trunnion Welded Body Ball Valves typical application is for gas transmission, buried pipelines (underground), larger sizes (up to 60 inches) and medium pressure classes (up to ASME 900 psi). Raw material can be either forgings or centrifugal castings. Wide range of materials: carbon steels, austenitic or martensitic SS.

The most traditional, widely used, on-off valve FLUITEK ORSENIGO VALVES’s approach to manufacture this type of valve is to maintain high integrity of components, traceability, process controls and tests in order to supply a superior product to for particular customers demands.

Fluitek Orsenigo Valves has a very extended experience in manufacturing this type of valve. It’s the most well known on-off valve for high pressure applications.

This type of on-off valve is an alternative to the traditional wedge type gate valves. The disc is in two halves, spring loaded, that seat on parallel seat rings. The disc “slides” in contact with the seats, hence the name. The advantages of this product versus the traditional wedge type product are: the disc never blocks in closed position (phenomenon that may occur with a wedge type that is closed with the line in temperature and opened when the line is cold). The opening/closing torque is much lower than a corresponding wedge type valve, resulting in less expensive actuation systems. The “sliding” feature keeps dirt away from the seating surface.

FLUITEK ORSENIGO VALVES has a very extended experience in globe valves manufacturing. In this kind of valve, the disc is moving in a perpendicular direction away from the seats. This implies the disc-to-seat ring contact to be at right angle, which permits the force of closing to tightly seat the disc, reducing the seat leakages. Normally, the globe valves are arranged so that the disc closes against the direction of fluid flow.

FLUITEK ORSENIGO VALVES has a very long experience in supplying this type of non return valve. It’s the most used one by the industry, normally coupled with on-off bolted bonnet gate valves and globe valves. Most used standard of reference are API 6D, regular opening, API 594, BS 1868. EN and ISO standard can also be referred to.

The on-off pipeline valves included in FLUITEK ORSENIGO VALVES lines of production (ball valves, through conduit gate valves) need very often to be installed in lines subject to “pigging” operations, either for lines internal periodical cleaning and/or for checking status of corrosion of the pipeline. In this case the non return valves need to present no obstacle to the passing of the pig.
