The Tri Lok® Cryogenic Triple Offset Butterfly Valve complies with various international standards and certifications, including API 609, ASME B16.34, ASME VIII, API 600, ASME B16.5, ASME B16.47, EN 1092, ISO 7005, ISO 5208, EN12266-1, API 6D, API 598, BS 6755, API 607, ISO 10497, PED, PE(S)R, SIL,

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.

The trunnion mounted 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 around it. Sealing is assured by pressure & spring energized seats. For small sizes, the ball is supported by a trunnion, while

Trunnion ball valves have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cav

The double expanding gate valve uses a two-piece gate-and-segment assembly: at full closure (and full opening) the two halves are mechanically wedged apart, pressing both seats against the body with a positive mechanical force that does not depend on line pressure. The result is a bubble-tight seal

The slab gate valve (model B11) uses a single-piece gate with a full circular bore, running between two floating, spring-loaded metal-to-metal seats. Line pressure pushes the gate against the downstream seat, providing the seal; in open position the conduit is completely unobstructed, allowing piggi

Special valve constructions to allow easy on-site maintenance and disassembly with quick access to ball and seats for inspection and repair.

Floating ball valves, construction to ASME B16.34 – ASME VIII Div.II, 2 piece bolted body, split body,side entry, flanged RF/RTJ to ANSI B16.5, face to face to ANSIB16.10, full/reduced bore, ISO (5211) top work standardized for actuation, metal seated (ball & seats with Tungsten or Chromium Carbides

The Top Entry ball valve design is characterized by one-piece body construction with top access to all internal components. Top Entry Ball Valves are the preferable solution when it is required to perform in line maintenance and when the reduction of possible leakage path is mandatory. The body can

Check valves prevent flow reversal automatically, without external actuation. Valland manufactures two families: the swing check valve (model C11), with a hinged disc in a single-piece bolted-bonnet body, available with renewable or fixed seats, soft sealing or metal-to-metal, and a lockable disc op

The standard ball valve is designed for applications with filtered and treated gases, for moderate minimum and maximum temperatures. This valve configuration is the most competitive in terms of price and lead time. Depending on pressure, size, and service, a floating or trunnion-mounted version is a

The standard trunnion-mounted top-entry ball valve is designed for filtered and treated gas applications and for moderate minimum and maximum temperatures. This valve configuration is the most competitive in terms of price and lead time.

We have a complete line of subsea ball valves, which can be offered side entry, top entry or twin ball design, for both shallow water and deep-water application up to 3000 meters water depth.

Starline manufactures a complete line of Subsea ball valves. Our Subsea ball valves are available in an extensive range of designs, materials, sizes and pressure classes and are in full conformance with API 6DSS, NACE and ASME VIII specifications. Starline uses only high-quality forged materials i
