Improve your Low-Temperature Valve & Manifold Instrumentation Installations with TESCOM™ Anderson Greenwood Instrumentation P Series & H7 Series Low-Temperature Bonnet!
The TESCOM™ Anderson Greenwood Instrumentation P Bonnet & H7 Bonnet Low-Temperature Series are an extension to the existing product range. This Series provides flexible, robust, and compact designs for static pressure on/off instrument process isolation across various valve configurations. Low-temperature design requirements are met even with a compact size and reduced weight. Installation processes are improved by minimizing the need for extended bonnets and providing bubble-tight shut-off performance required on instrument isolation applications.
Available in 316 stainless steel, PTFE or Graphite stem packing and covers an operating temperature range down to -191º C (-312º F). Low-temperature bonnets are suitable to be supplied across the range of metal seat type manifolds, hand & gauge valves providing a broad selection range for optimum coverage. The optional H7 extended bonnet version will be available to satisfy applications where instrument piping insulation is necessary.
