New non-destructive leak tester for packaging
Witt Gas Techniques has introduced a new system for non-destructive testing for leaks in individual flexible and rigid food and pharmaceutical packaging based on CO2 detection technology
Until now these spring-loaded, direct-acting safety relief valves were only available for opening pressures of 0.5 to 45 bar.
The new models in the SV809/810 range are suitable for all pressure levels between 45 and 100 bar.
In addition the Type SV810 features manual venting, to enable a safety test to be performed after the valve has been fitted.
Safety relief valves are required to vent excess pressures in receivers/vessels, pipelines and other equipment.
Light in weight at around 260g, this safety valve from Witt is suitable for all technical gases.
The opening pressure can be set individually by Witt to meet on-site requirements.
The valves, which are available in brass or stainless steel, can be fitted in any position or orientation and their compact size means that they are easy to install.
Witt supply the new safety relief valves with a range of inlet connections, a protective dust cap and an optional condensation outlet.
These models comply with the Pressure Equipment Directive 97/23/EG Modules B and F, have TUV certification and, depending on gas type and valve seal, function within a temperature range of -196 C to +300 C.
The original "smaller" versions with a maximum opening pressure of up to 45 bar are still available.
