Boiler Level Control Parts

Primary & Auxiliary / Secondary Low Water Cutoffs
York-Shipley Burner Models

Primary Low Water Cutoffs

A boiler's primary low water cutoff is a mechanical device with  multiple functions:
  • Senses water level in the boiler through a mechanical float and shuts the boiler down if water level decreases
    • Primary low water cutoffs are typically automatically reset, meaning the boiler can automatically restart once water level is restored
  • Provides a rigid body to connect a gauge glass and try cocks
  • Regulates boiler water level via on-off pump control or by sending an open/close signal to a modulating feedwater valve

Gauge Glasses & Try Cocks

Gauge glasses are used to provide visual indication of water level in a boiler. Typically the gauge glass is mounted directly to the boiler's primary low water cutoff via 1/2" NPT connections machined into the LWCO body. A complete gauge glass assembly typically consists of:
  • Gauge glass fixture consisting of upper and lower isolation valves
  • Metal rods to protect the glass from being hit
  • Drain valve available on some models
  • Tubular high temperature glass
  • Gauge glass washers to create a seal between the glass and the fixture
Trycocks are sometimes installed into the LWCO body to serve as a backup method of water level indication. If your gauge glass is temporarily inoperable or needs to be verified, trycocks can be used to identify approximate water level by slowly bleeding steam or water through the try cock.
