This spring-closing oil drain valve allows for draining oil from an ammonia refrigeration system while the system is still operating, says the company. The valve is available in 1/2- and 3/4-in. sizes with threaded connections. The unit features an all-steel body, non-asbestos packing and gaskets, neoprene seat disc, and zinc-chromate finish. The valve must be used in series with a hand shut-off valve connected to the inlet side. A spring-loaded seat in the valve will open and relieve pressure on the inlet side at approximately 290 psi, the company says.

Henry Technologies, Inc., Flow Control Products, 3215 North Ave., Melrose Park, IL 60160; 800-323-4052; 708-344-1145 (fax); www.henrytech.com (website).
