Comstock Castle 18-63 Burner Valve 1/8" MPT X 3/8"-27

This manual gas burner control valve regulates fuel distribution to individual heating elements by physically metering the gas supply through an adjustable manual spindle. Outfitted with a 1/8-inch Male Pipe Thread (MPT) inlet connection and a 3/8"-27 threaded outlet structure, this 90-degree angle valve accepts low-pressure gas line setups and directs raw fuel straight into the mixer head. Its downward-pointing, 0.240-inch diameter stem delivers tactile control over fuel outputs, establishing an immediate on-and-off rotation pattern that prevents gas leakage when closed. Sustained physical strain and heat exposure can loosen internal seals over time, making a fresh control valve replacement an ideal solution to remedy issues like weeping fuel lines, unresponsive flame adjustments, or flickering pilot light failures. Measuring exactly 2 inches from the center inlet point to the edge of the control stem, it coordinates naturally with standard front-panel knob layouts on heavy commercial cooking assemblies. This control switch is standard across high-intensity foodservice sectors inside counter commercial broilers, standalone griddle plates, commercial salamanders, infrared cheesemelters, and heavy-duty stockpot hot plates to lock in stable cooking performance and prevent fuel waste.

"After installing this valve, gas flow became much more controllable, and the burner responded immediately."

Step1: Turn off gas or fluid supply and fully relieve pressure before starting installation to ensure safety.

Step2: Apply PTFE thread sealant tape to the 1/8 MPT male threads evenly.

Step3: Align valve with 3/8-27 fitting and hand-thread carefully to avoid cross-threading.

Step4: Tighten using a wrench until snug, avoiding over-torquing or damaging threads.

Step5: Restore supply slowly, check for leaks with soapy water, and test operation.
