Valves, Fittings & Manifolds

Spina Group offers a wide range of measuring instruments. The company manufactures and supplies instrumentation valves and manifold, pots and siphons, fittings and adapters and industrial tubings.

The processes of chemical and petrochemical plants both onshore and offshore require the regulation of the values ​​of physical and / or chemical parameters in order to maintain a correct efficiency of the plants themselves. Furthermore, the demands on instrumentation systems designed for offshore applications continue to grow.

Since the oil and gas sector seeks to exploit ever deeper and less accessible reservoirs, instrumentation systems must be able to operate at significantly higher pressures, particularly in subsea equipment used for projects with long life cycles. A wide range of accessories is available too.

Our Offer

Manifolds and Valves

Spina Group offers different types of pressure measuring instruments, including manifolds and valves suitable for static pressures, applications with liquids or for differential pressures, available for different types of installation and with different styles and designed to provide a safe and reliable method of measurement pressure and versatile towards installation within the process.

Compression Fittings

Spina Group offers a wide range of fittings, caps and reductions which ensure the absence of leaks (even in the presence of gas), good resistance to high tightening, easy assembly with the possibility of repeated assembly and disassembly.

Pots and Siphons

Spina Group offers a wide range of condensate separation barrels, air distribution and siphons, which are used for the treatment and distribution of the process fluid before it reaches the instrument.

The siphons are used on the steam measurement lines to prevent it from directly investing the instrument and also to guarantee good heat dissipation avoiding overheating of the pressure gauge.

Tubing

Spina Group offers various types of cable holders for explosion-proof electrical systems and UL type and flexible pipes necessary for the construction of suitable “electrical conduits” inside walls and floors so that the electrical cables are protected from impact, humidity and compressions.

Latest successful projects

Petrochemical

Beaumont 3000 MTPD Synloop Ammonia Plant

The Beaumont New Ammonia Project, located in Beaumont, Texas, USA, is a major lower-carbon ammonia facility with a production capacity of 3,000 metric tonnes per day (1.1 million tonnes per year). Owned and operated by Woodside, the project is designed to expand the supply of lower-carbon ammonia for applications including power generation, marine fuels, and industrial feedstock. A key milestone was achieved in December 2025 with the successful production of first ammonia during commissioning.
