1. Floatless Liquid Level Controllers

2. No float! Large connection opening is not necessary. No worry about inside clearance.

3. 12 PL To Separator Gas Space To Separator Liquid Space Single adjustment for Changing liquid level No float required Easy installation 125 psi max. WP Single soft seat for tight shutoff One adjustment for throttling Or semi-snap operation

4. 12 PL Upper adjusting screw changes liquid level Standard spring: Max. level of 4 feet Lower adjusting screw: Turned in—throttle (1”span) Turned out—snap from 6” to 8” up to 2’ to 2-1/2’

5. 12 PL Installation Do not use equalizing line as a source of gas for any other device. For best operation, the pilot should be at least 4” below the desired liquid level.

6. 12 PDS Differential Pilot Maintains Differential for Flow Control Maintains Liquid Level No float required Use with Pressure Closing Dump Valve Throttle Control Uses separate supply gas pressure: 5 to 30 psi Spring Ranges: Standard up to 36 inches Optional up to 100 inches 125 psi max. WP
