CG-1968-GL-2: New generation drain valves


The detachable drain valves of the Chemglass process reactors have always been one of the most useful features of the systems. Chemglass now launches a new version of this part.

The new CG-1968-GL-2 bottom valves will now replace the CG-1968-Q and are compatible with all new and existing Chemglass reactor systems. Replacement parts for the CG-1968-Q valves remain available and are also available for the new part.

The “Zero Dead Space” flush bottom valve is designed to prevent solids from collecting in the bottom of the vessel. The PTFE drain valve plunger is supplied with a Perfluoro and a TFE encapsulated o-ring for the tip and two Perfluoro o-rings installed on the shaft. The drain valve is connected to the reactor by a unique 2” beaded pipe valve seat that is sealed to the reactor bottom. Our valve permits total drainage of the vessel contents. The sidearm has a 1” beaded pipe fitting. There are two types of plug assemblies; the first is the plain plug for use with our standard agitators; the second has a stabilizing pin that is used with the 100L agitators. The pin extends into the lower agitator and virtually eliminates any whipping by stabilizing the stirrer shaft.


Glass Body Features a Heavy Duty GL Style Glass Thread

Auto-Stop When Opening the Valve

Anodized Aluminum Control Knob is Laser Etched with Directional Arrows for Opening and Closing the Valve

Zero Dead Space

Perfluoro O-Rings on Tip and Plunger

The new valves come in 2 versions:
