Coi Technology

What Coi Technology does

Coi Technology Srl is an Italian privately held manufacturer specializing in safety relief valves, founded circa 1984 and headquartered in San Giuliano Milanese near Milan. The company operates a single-site production model with a modern CNC machine park and a strict material-control regime including Positive Material Identification (PMI) testing before and after processing. Its portfolio comprises two core series: the SLK line for compressible fluids (steam, gases, compressed air) and the GLV line for incompressible fluids (liquids), with both offered in multiple types, orifice sizes (8–38 mm), connection standards (GAS, BSP, NPT, DIN, ASME), and a broad material range spanning stainless steel, titanium, brass, bronze, Duplex, Hastelloy, Incoloy, Monel, and plastics (C-PVC, PVC, PP, PVDF, PTFE). All valves feature full-nozzle construction and are supported by accessories (bellows, heating jackets, test gags, lifting levers) and spare parts (gasket kits, discs, nozzles, springs).

The business model is direct B2B manufacturing with quote-based pricing driven by detailed technical configuration. Sales are generated through an online quotation request system, participation in three major European exhibitions (Valve World Expo Düsseldorf, IVS Industrial Valve Summit Bergamo, Hydrogen Expo Piacenza), and a multilingual corporate website available in 8 languages. Coi Technology holds a comprehensive international certification stack — PED 2014/68/EU, ATEX 2014/34/EU, UKCA, EAC-TR CU, M.O.C.A., and ISO 9001/14001/45001 — alongside third-party marine approvals from TÜV, DNV-GL, Lloyd's Register, RINA, and ABS, with flow-coefficient validation performed at Politecnico di Milano. End markets span chemical, petrochemical, LNG/CNG, hydrogen, pharmaceutical, naval, power and energy, and water treatment, with no named anchor customers disclosed.

Revenue is not publicly disclosed, there is no evidence of external funding or institutional investment, and ownership appears to remain with founders or insiders. The company is classified as a privately held Italian limited liability company (S.r.l.) with no subsidiaries or parent entities.

Core offering

Coi Technology manufactures safety relief valves for industrial applications, producing two main series: the SLK series for compressible fluids (steam, gases, compressed air) and the GLV series for incompressible fluids (liquids). The valves are produced from bar stock using in-house CNC machines, with full-nozzle designs available with threaded or flanged connections (GAS, BSP, NPT, DIN, ASME) in materials ranging from plastics (C-PVC, PVC, PP, PVDF, PTFE) to specialty alloys (Duplex, Hastelloy, Incoloy, Monel). The company also supplies complementary accessories (bellows, heating jackets, test gags, lifting levers) and spare parts.

Product overview

Coi Technology is a manufacturer of safety relief valves with two core product series: the SLK series for compressible fluids and the GLV series for incompressible fluids. Both series feature full-nozzle designs with threaded or flanged connections (GAS, BSP, NPT, DIN, ASME) and are available in multiple types, sizes, and materials including plastics, brass, stainless steel, Monel, and Duplex. The company also offers a range of accessories (bellows, heating jackets, test gag, lifting levers) and spare parts (gasket kits, discs, nozzles, springs). The SLK series offers Types A through I, while the GLV series includes standard and plastic versions (Types A through F). The portfolio is supported by PMI testing services and custom project engineering.

Broad incumbents

• Watts Water Technologies: Large US-headquartered flow-control platform with pressure relief and safety valves across water, plumbing, and industrial markets. Broad incumbent whose safety valve line intersects Coi's water-treatment and industrial verticals at much greater scale.
• Spirax-Sarco Engineering: Global steam-specialty and fluid-handling group whose safety valve and pressure relief portfolio overlaps with Coi's compressible-fluid applications (steam, gases). Broader incumbent with adjacent, partially overlapping offerings.
• Velan Inc. Canadian manufacturer of industrial valves including safety/relief valves for power, oil & gas, and chemical. Broader incumbent in industrial valves with overlapping pressure-safety applications but a much larger product portfolio.
• Pentair Flow Control: Large diversified flow-control platform including pressure relief solutions across water, industrial, and energy. A broad incumbent whose portfolio overlaps with Coi's but with much wider scope and scale.
