Product Description

120/110 Volt Internal Pilot Solenoid Valve

The Mac Valves 811C-PM-114JB-152 is part of the 800 series. This 120/110V single solenoid valve is a two way internal pilot version with locking extended manual operation, a rectangular connector, and 1/4" female NPT ports.

The MAC 800 Series features Mac Valves' balanced poppet in the pilot and an air/spring return for consistent shifting regardless of inlet pressure fluctuations. Mac's balanced spool means the valve can be piped as a 4-way, 3-way, 2-way, normally closed or normally open or can be used for vacuum, diverter or selector applications. The one piece bonded seal spool means longer life and easy maintenance.
