Manufactured in accordance with a wide range of international standards and approvals such as TÜV (Germany) to AD Merkblatt A2, National Board UV Stamp to ASME Section VIII Division 1, EAC customs union (Russia, Belarus and Kazakhstan), the Canadian CRN and compliant with the requirements of the Pressure Equipment Directive 97/23/EC (CE marked).
LGS Safety Relief Valves from Stock - Multi-purpose valve suitable for Liquid, Gas and Steam applications.
All of our valves are available from DN15 to DN50 (1/2" to 2" BSP female connections), Pressure range is 0.2 to 24 bar g. (depending on seal and duty)
This valve is used if a plant shutdown is impossible or undesirable for process engineering or commercial reasons. With change-over valves it is possible to switch over between parallel safety valves without interrupting operation, so that maintenance work can be carried out on each safety valve in turn.
Seetru Compu-test™ is a comprehensive computerized safety valve diagnostic system add-on for conventional safety valve test benches. Using the Compu-test™ system enables objective diagnostic analysis of the critical assessment criteria for safety valves, namely:- Set Pressure, Seetru Condition Rating® and Bubble Leak Rate.
The Compu-test™ system can be used in either manual or automatic analysis modes. In automatic mode the Compu-test™ system automatically evaluates all the key diagnostic parameters extremely quickly and objectively, the user can also carry out the same evaluation entirely in manual mode. In either mode it is fast and simple to use. Experienced and inexperienced safety valve technicians will find the Compu-test™ system intuitive and easy to use.
This compact, light weight and portable design is very robust and able to meet the demands of a busy maintenance workshop or mobile operation. The Quicktester™ can be used with plant generated air supplies or with mobile bottled gas. This test bench is supplied with a range of adaptors allowing connection between 1/4" to 1" BSP as standard, additional adaptors are available increasing the connection sizes up to 2" BSP. The Quicktester™ is also available with NPT connection adaptors on request.
