Stainless Steel Level Gauge Valves

The Importance of Stainless Steel Level Gauge Valves

Level gauge valves are essential components in industrial systems that require precise liquid level measurement in tanks and pressurized vessels. These valves allow for the control and regulation of liquid flow into the gauge glasses, ensuring reliable and safe level readings. This is crucial in applications such as boilers, refineries, chemical plants, and distilleries, where accurate monitoring of liquid levels is vital for operational safety and efficiency.

Installation of the Level Gauge Valves

Preparation

  • Inspect all components for damage.
  • Ensure all parts are clean and free of debris.

Installing the Top Fitting

  • Apply Teflon tape to pipe threads.
  • Install the top gauge fitting into the uppermost tapping, ensuring the glass outlet is at a 5 o’clock position (about 1/8 turn from its final, downward vertical position).

Installing the Bottom Fitting

  • Install the bottom gauge fitting with a plug into the lower tapping, ensuring it is pointing directly upward. Make sure the top and bottom fittings are threaded into the tappings the same number of turns.

Removing and Placing Packing Components

  • Remove the glass packing nut, friction washer (or packing gland and retaining ring), and glass packing from both fittings.
  • Place these components back onto the ends of the gauge glass, pushing the packings about an inch up the gauge glass.

Inserting the Glass

  • Gently insert one end of the glass into the top fitting. Rotate the top fitting clockwise until vertically aligned with the bottom fitting, then insert the glass into the bottom fitting until it bottoms out on the shoulder inside the bottom fitting.

Positioning the Glass

  • Raise the glass about 1/16” and slide the lower glass packing down until it contacts the lower fitting. Ensure the glass does not contact any metal.

Securing the Packing

  • Slide the upper glass packing up as far as possible.
  • Hand tighten both packing nuts, then tighten an additional 1/2 turn with a wrench. Tighten only enough to prevent leakage without over-tightening. Adjust slightly if any leakage occurs, checking for leakage after each turn.
