155L Position Indicator

The Model 155L Visual Indicator is a device that enables the user to determine the extent of
opening of a control valve. It consists of an adaptor threaded into the main valve bonnet, a
rod threaded into the main valve stem, a sealed Pyrex sight glass, and protective stainless
steel housing. The indicator rod moves as the main valve opens and closes. The 155L may
be installed on virtually any OCV Model 65 Control Valve that requires only visual indication.
Installation can be done without disassembly of the main valve. The 155L provides a convenient
point for bleeding the air during system startups via a screw located on the top
adapter.

WHERE USED – The 155L is the standard visual indicator on military fuel service valves for
Jet fuel or Avgas service. Optional on virtually any control valve not already employing a
limit switch or position transmitter.
