Commitment to safety

TAKEI CO.,LTD is a qualified manufacturer of safety valves for high-pressure gas.
This is a safety valve used in a high-pressure gas facility mainly by high-pressure gas production enterprises. We have recognized that this valve plays an important role of being activated in the case of abnormal pressure rise due to certain reasons, thereby preventing a disaster before it actually occurs.
The overall quality requirements presented by customers are extremely high, and we are making tireless efforts day and night for research and development as well as improvement of a production system to meet the demand.
We are fully aware that we have a responsibility, as a test laboratory qualified by the Minister of International Trade and Industry, for high-pressure gas facilities and we will make the best of us to ensure the safety of customers among other things.

Maintenance

Be sure to carry out maintenance of the safety valve after installation. Determine the maintenance cycle according to the condition(environment)in which the safety valve is installed and applicable legal regulations. Negligence of maintenance may cause malfunction of the safety valve.
The performance can be guaranteed only when the maintenance including disassembly and inspection is made.

Cautions for Installation of Safety Valves

Pay attention to the following points during installation of the safety valve :

  • Install the safety valve in a vertical condition.
  • Eliminate dust(including fine dust, such as metal powder, etc.)in the piping as much as possible. The safety valve may contain such dust in the seat when activated, resulting in leakage from this seat.
  • When carrying out piping on the outlet side, be sure to use the piping inside diameter(bore)larger than the inlet diameter Never apply unreasonable force.
  • Minimize the pressure loss to the safety valve inlet. (The target must be 3% or less of the set pressure.)
  • Install the safety valve as near as possible to a bessel which should be protected with this valve.
  • Never apply a spanner to a position other than specified. Always apply the spanner only to a hexagonal(or a flattened)portion of the main body. If the spanner is applied to other portions and the screw becomes loose, the opening pressure of the safety valve may change.
