The double seated No. 62 lever valve, when used in conjunction with a lever valve controller, is well suited for the automatic control of the supply of liquids to an enclosed tank where dead-end closing is not essential and where valve inlet pressures are normal. Many thousands are in use on both large and small water, oil, and chemical storage tanks in all types of industries. The No. 62 lever valve is most commonly operated by external linkage to the lever from either an internal float such as the No. 20M, No. 20, or by an electric solenoid, diaphragm motor, or hydraulic cylinder.
The single seated No. 73 internal pilot controlled lever valves, when used in conjunction with a lever valve controller, are well suited for the automatic control of the supply of liquids to an enclosed tank where dead-end closing is essential. Both globe and angle pattern bodies are available in every pipe size. The path of flow through the NO. 7 lever valve with the angle pattern body is in through the side and out through the bottom while the globe pattern body has a side inlet and side outlet. Many thousands are in use on water, oil, and chemical storage tanks in all types of industries. These lever valves are best suited for clean liquids not injurious to neoprene, brass, or iron parts and where the standard design temperature is below 125°F. The neoprene valve disc can be replaced with Teflon for temperatures above 125°F and below 350°F.
The No. 762 lever valve is recommended for applications requiring a tight closing valve for cold or hot liquids which are not injurious to the rubber diaphragm or disc, and for pressures up to 150 PSI.
The ball type inner valve, which has been used for years with excellent results in other valves, is now being built into float and lever valves. It provides a simple and durable, tight closing construction suitable for any ordinary fluid at temperatures up to 406°F.
