Fire hydrant pressure-reducing valves

Safety Systems developed the Class-F fire hydrant pressure-reducing valves more than 30 years ago, and have delivered several thousand valves to the offshore industry in aluminum bronze, 6MO, duplex or titanium body materials according to NORSOK standards.

Safety Systems inlet flange connections are available in either 1.5in or 2in ANSI 150/300. In addition, the manufacturer supplies a standard outlet connection, in either 2.5in BS 336 instantaneous female coupling or screwed 2.5in BSP, which is made to suit internationally recommended adaptors. The maximum inlet pressure is 20.7bar(g) with an outlet pressure range between 4.1bar(g) and 8.3bar(g).

Transparent, reflex and magnetic-level gauges

Simco produces level gauges for the oil and gas industry in a wide range of materials, including carbon steel, stainless-steel, duplex, super duplex, hastelloy, titanium, 6MO and monel.

Solaris LED illuminators for transparent liquid level gauges

In order to meet the market demand for low-weight, reduced cost, easy installation and long-life explosion-proof illumination for transparent liquid level gauges, J.S.Cock has developed a new-generation Solaris LED light system.

The solution does not only meet those demands, but it also offers full customisation with regards to module length, voltage and LED light colour. All external components are made of stainless-steel 316, which provides excellent corrosion resistance.

The system is easy to install, takes up minimal space, has a long operational lifetime and does not require any maintenance. The LED lights are moulded in a clear casting epoxy resin, which offers high IP-protection and can be used in explosive atmosphere environments. The system is module-based, and with in-house manufacturing takes place in Oslo.
