Company profile

Seetru is the principal company of the Seetru Organization, a small integrated group of subsidiary and associated companies. The Organisation includes Ebtrade, which trades as Leser Valves, and Seetru Engineering Services, which specializes in safety valve test, maintenance and maintenance management services.

The group has a staff of over a hundred and twenty people and a turnover of in excess of £6 million. The Seetru Organization represents a comprehensive, vertically integrated engineering enterprise, comprising: Sales and Marketing, Design and Development, Production, Administration etc. The production department has the most up to date machining facilities and organizational practices. All aspects of operation are supported by extensive and up to date information technology systems.

The growth of the Company for over 50 years has depended upon the development and perfection of valve and gauge products, especially in the field of safety valves. The Company is supported by its ethos of engineering excellence and great attention to customer’s needs. It operates a substantial approved development test plant for safety valves, and also has environmental test facilities for all its products.

Seetru operates comprehensive Quality Management, Safety and Environmental Protection Systems. It is approved to BS EN ISO9001:2000 by Lloyds Register of Quality Assurance (LRQA).

Seetru Limited has a special interest in export, an example, is liquid level gauges for marine and shipbuilding industries which are sold worldwide. The Company is active in strengthening and expanding its international position in Europe and elsewhere; it has, for example, an important Far East trade and has granted manufacturing licences in Japan.

Seetru products and services
Seetru are manufacturers of safety relief and other special purpose ancillary valves for a wide range of compressed air, industrial gas, refrigerants, powder, steam, liquid and liquefied gas applications. These valves meet important international standards, which include: the BS 6759 Parts 2 & 3, AD-Merkblatt A2, ISO 4126 and ASME Section VIII design codes, as well as type test approvals from TÜV and the National Board. The products comply with the requirements of the European Pressure Equipment Directive and are available both CE marked and UV stamped.

Seetru has a wide range of special purpose valves, which are largely for the compressed air industry and for medium sized industrial oil engines. These include minimum pressure maintaining valves for screw type compressors and air starting valves for medium size industrial and marine oil engines.

Seetru liquid level gauges are primarily of two types, sight gauges and magnetic float by-pass gauges. Many of the gauges are direct reading though most have optional electronic remote reading systems and computer interfaces.

The gauge range notably includes the Quickmount, Seemag and CPI gauges for industrial and chemical applications as well as the Seetol system for tall tanks (e.g. of 20 metres and above) incorporating optical and closed circuit TV viewing systems.

The Seetru ranges of gauges for marine applications have for many years been the great workhorse gauges in the marine industry. The current standard, the Seeflex gauge system, is approved by all important international classification societies, including Lloyds Register of Shipping, Germanischer Lloyd, NKK Japan, ABS, Det Norske Veritas etc. The Seemag magnetic float by-pass gauge is also widely approved for marine and off-shore applications.
Seetru Engineering Services provides on-site and/or off-site services specialising in safety valve testing, maintenance and maintenance management for all makes and types of safety valves. These services include in-situ on-line testing of safety valves as well as full safety valve inventory management services. In particular, the unique Seetru Condition Rating™ technology provides for health monitoring of safety valves in-situ in service and true calibration at overhaul. This division also provides outside engineering services for the installation and maintenance of other Seetru products.

The Company’s substantial design and development department enables it to provide extensive bespoke design, advisory and manufacturing services to develop or adapt individual products to new applications.

Seetru provides training courses covering the use and maintenance of its own and similar products. In particular, these concern the specification, installation, operation and maintenance of safety valves.
