Information About 250E1
The 250E1 is part of Humphrey’s 250 series of diaphragm-poppet pneumatic valves. Its internal pilot uses supply pressure to operate the main valve, with spring assistance returning the mechanism when electrical power is removed. The specified configuration supports direct piping and uses lead wires for electrical connection. Its soft-sealing design operates without added air-line lubrication and suits pneumatic isolation and supply-control applications.
Key Features:
- Two-Way Configuration: Opens or closes the pneumatic flow path in the supplied -2 version.
- Normally Closed Function: Blocks the controlled flow path when the solenoid is de-energized.
- Single-Solenoid Actuation: Uses one electrical coil to command valve switching.
- Internal Pilot Supply: Uses inlet air pressure to operate the diaphragm-poppet mechanism.
- AC Coil Operation: Accepts 120 V AC power at 50/60 Hz in the listed configuration.
- Spring-Assisted Return: Returns the valve mechanism after the control signal is removed.
- Direct Piping: Provides 1/4-inch pipe connections for installation into pneumatic circuits.
- Oil-Free Operation: Requires no added lubrication in the compressed-air supply.
The 250E1 delivers the reliability and precision required for electrically controlled pneumatic flow switching in automated machinery.
