Innovation from the very beginning Seetru was founded in 1949 by Otto Varga and Leonard Taylor. The aim of their early collaboration was to solve a common problem within the oil industry; typically oil was stored in tanks or drums and the only available method of understanding how much volume remained was through an audible confirmation ...usually achieved by kicking the drum.

The two entrepreneurs began work and soon devised a method of measuring the level of tank or drum contents with accuracy and efficiency. Thus the ‘Seetru Gauge’ came into being and the name Seetru was established - ‘See the Tru’ level.

The Seetru Gauge, although a hugely successful tool, wasn’t without its problems.

The Gauge itself relied upon valves in order to operate. These valves were regarded by Mr Varga as being inefficient and “quite terrible” - frequently leaking oil.

His knowledge of elastomer’s/polymers and huge enthusiasm for invention would lead Otto Varga to design and develop a new push valve for the Seetru Level Gauge, which, with its design quality and innovative use of the O-ring, produced a device which no longer suffered from leaking.

Encouraged by the success of this instrument and recognising that there was a need for better, more efficient design within the valve industry and related applications, Mr Varga began work on a new range of safety relief valves.

From the early development of the Seetru Gauge came an extensive range of liquid level indicators ...and out of the valve development for that gauge, came the entire range of safety and relief valves Seetru design and manufacture today.

Innovations & Developments

• In 1964 Seetru developed a revolutionary sealing technology named the Tutchtite valve seal system. This advance achieved positive bubble-proof sealing for a wide range of fluid pressures, while requiring no polishing or lapping whatsoever of the valve seats.

• In the 1980’s Seetru gained the industry approval for its marine class liquid level contents gauges. The SOLAS (Safety of Life at Sea) Convention in its successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant ships.

• During the 1990’s Seetru applied our knowledge and expertise to bear on the refurbishment and testing of Safety and Relief valves for external customers, resulting in the official formation of Seetru Engineering Services (SES) in November of 1998. SES are now a major provider for PSV (and other) test and maintenance services ...we’ve established ourselves as the supplier of choice for many companies today in the UK and Globally.

Led by Andrew Varga and his wife Margaret (both PhD Chartered Engineers), the company is flourishing and increasing turnover year on year, entering new markets with the same enthusiasm vas those with which we are already well established.

The company remains committed to giving opportunities to young individuals, enabling them to learn and grow within the organisation.

Our success is determined not only by our design innovations but also through the agency of our skilled and dedicated people.
