This air operated, flush bottom drain valve fits Chemglass reactors from 10 to 50 liters that have a 2 beaded pipe connection. Valve is perfect for applications where solvent extractions or partitioning are done after a reaction. Due to the constant spring tension on the plunger, the valve is great for use during low temperature reactions where standard valves need constant tightening to prevent leakage. Valve is held closed against the bottom of the reactor via spring force and is opened by air pressure. A second regulator is used to supply 4 psi of air pressure as a safety back-up to the spring. The wetted portion of the valve consists of a PTFE plunger tip and drain valve body. Perfluoro o-rings and Hastelloy shaft. The air control panel can be mounted anywhere on the reactor using a CG-9253 Universal Kwik Klamp. Complete valve kit is supplied with two regulators, mounting bracket and all tubing and fittings needed for hook up.
