The Cast Air BE2-M is a 2-way pilot valve built for electric dual-application compressors. If your electric-drive compressor system needs a reliable unloader or capacity control valve — something that holds up under daily cycling without leaking down or hunting — this is a straightforward, well-built component from a manufacturer that has been making compressor hardware for decades. The 1/4" NPT-F inlet keeps installation simple on standard compressor manifold ports, and the direct vent with felt filter handles the exhaust cleanly without a separate exhaust port plumbing run.
What the BE2-M Does
- Application: Electric dual-application air compressors — controls loading and unloading cycles to match air demand
- Valve Type: 2-way pilot valve — two ports, one state change per signal, simple and reliable
- Inlet: 1/4" NPT-F — threads directly into standard compressor manifold or control line ports
- Vent: Direct vent with integral felt filter — exhausts signal air through a filter element to prevent contamination ingestion and keep the exhaust quiet
- Flow Capacity: 20 max CFM — appropriate for 1/4" ported pilot circuits on single-stage and two-stage electric compressors
- Pilot Ports: 1/8" female NPT — standard signal line connection size
Construction and Adjustment
- Body: Hex brass — machines cleanly, threads without galling, resists corrosion in typical compressor room environments
- Pressure Adjustment: Full external pressure adjustment — set your cut-in and cut-out pressures at the valve without disassembly
- Differential Adjustment: Full external differential adjustment — dial in the spread between cut-in and cut-out to prevent short-cycling
- Pressure Range: 40–250 PSI available; most electric shop compressor applications order the 100–120 PSI or 140–170 PSI range versions — confirm your system's working pressure before ordering
- Corrosion Resistance: Corrosion-resistant construction throughout — holds up in humid compressor rooms and industrial environments
Where This Valve Fits
- Replacement for OEM pilot valves on electric reciprocating compressors
- New installations where a quality 1/4" pilot valve is needed for a dual-control circuit
- Service situations where the original valve is hunting, leaking, or sticking — swap this in and re-adjust to spec
- Not for gas engine applications — the BG2-M covers that version
- Not for higher-flow 1/2" circuits — step up to the BLE (60 CFM) if your control circuit demands it
BE2-M vs. the Cast Air Pilot Valve Lineup
- BE2-M (this valve) — $91.63: 1/4" NPT-F, 20 CFM, electric dual, direct vent with felt filter
- BG2-M — $78.54: Same 1/4" NPT-F, 20 CFM, same direct vent — but for gas engine applications; lower price point
- BLE — $123.20: Steps up to 1/2" NPT-F inlet and outlet, 60 CFM, electric dual — for larger compressor circuits
- BLG — $147.84: 1/2" NPT-F, 60 CFM, gas engine version of the BLE
If you are replacing a failed pilot valve on an electric compressor and your control circuit is 1/4" ported at 20 CFM or less, the BE2-M is the correct part. If you are unsure whether your system needs the 20 CFM or 60 CFM version, measure the pilot port size at the compressor — 1/4" NPT ports take the BE2-M, 1/2" NPT ports take the BLE.
