Ashcroft
Ashcroft LPAN4HV25XCYLM100 Pressure Switch 10-100 psi DPST 4 Ports 1/2" FNPT
A pressure switch with a 10 to 100 psi range, 10 A AC and 0.5 A DC contact ratings, and NEMA 4, 4X enclosure rating
- 10-100 psi range covers wide pressure needs
- DPST contact form controls two circuits simultaneously
- Four ports with 1/2" FNPT simplify multi-line installation
- NEMA 4 and 4X rating resists wash-down and corrosion
- 10 A AC rating handles standard motor loads
Pressure Switch 10-100 psi DPST
The Ashcroft LPAN4HV25XCYLM100 is a diaphragm-actuated pressure switch designed for industrial control circuits. It operates across a 10 to 100 psi range with a differential of 10 to 90 psi. The unit carries NEMA 4 and 4X ratings for environmental protection.
Suits pump and compressor control
This switch fits applications requiring on/off actuation at factory-set points near 90 percent of the range. It is not suited for systems needing adjustable differential settings or for circuits that exceed the listed AC and DC contact ratings.
Panel-mount with four 1/2" FNPT ports
The four-port 1/2 inch FNPT arrangement allows flexible piping without extra manifolds. SPDT contacts rated at 10 A for 125/250 V AC and 0.5 A for 125/250 V DC integrate directly into starter coils or PLC inputs.

Questions about this item
What power supply must I already have to use the 10 A @ 125/250 V AC or 0.5 A @ 125/250 V DC contacts?
You need a circuit that stays within 10 A at 125 or 250 V AC, or 0.5 A at 125 or 250 V DC, and a compatible 1/2" FNPT fitting for the four ports.
Will the switch operate correctly if my system pressure sits near the 10 psi low end or 100 psi high end of the range?
Yes, the differential spans 10 to 90 psi inside the 10 to 100 psi range, and the factory on/off point is set at 90 percent of range, so it functions across the full span.
How can I confirm the diaphragm is actuating at the right pressure after installation?
Pressurise the line and watch the SPDT contacts change state at the set point; the NEMA 4/4X enclosure lets you inspect the switch action visually.
