FESTO PEV-14-B Pressure Switch | 1-12 Bar Range, G1/4 Port, IP65 Specs

FESTO PEV-14-B Pressure Switch | 1-12 Bar Range, G1/4 Port, IP65 Specs

FESTO PEV-14-B pressure switch specifications. 1-12 bar adjustable range, G1/4 pneumatic port, 250V AC/125V DC switching capacity, IP65 protection. For industrial compressed air and water systems.

Product Overview

The FESTO PEV-14-B​ is a mechanical pressure switch​ from the PEV series, designed for monitoring and controlling pressure in pneumatic and hydraulic systems. This model features an adjustable pressure range of 1-12 bar, G1/4 threaded pneumatic port, and mechanical switching contacts​ (normally open/closed). The "14" designation indicates the port size (G1/4), while "B" specifies the pressure range configuration. This contact-type pressure switch provides reliable on/off control based on preset pressure thresholds, suitable for compressor control, pump protection, and system monitoring applications.

Technical Specifications

Note: Specifications are based on FESTO PEV series technical documentation. The "PEV-14-B" model specifically indicates G1/4 port size and 1-12 bar pressure range configuration. Actual specifications may vary slightly depending on production batch.

Model Number Decoding (PEV-14-B)

• PEV:​ Series designation (PEV pressure switch series)

• 14:​ Pneumatic port size (14 = G1/4 threaded port)

• B:​ Pressure range configuration (B = 1-12 bar adjustable range)

Note:​ The "14" designation corresponds to G1/4 port size according to FESTO's nomenclature system. The "B" suffix indicates the specific pressure range configuration (1-12 bar). Other variants may include different pressure ranges or port sizes.

Important Technical Notes

1. Pressure Range:​ The adjustable range is 1-12 bar. Do not exceed 14 bar maximum input pressure.

2. Media Compatibility:​ Suitable for compressed air (ISO 8573-1:2010) and water. Verify media compatibility for other fluids.

3. Electrical Ratings:​ Maximum switching capacity 250V AC / 125V DC, 4A. Ensure load does not exceed these ratings.

4. Mounting:​ Can be mounted in any position. Avoid excessive vibration or shock.

5. Setting Adjustment:​ Use appropriate tools for pressure setting adjustment. Lock the setting after adjustment.

6. Hysteresis:​ Mechanical pressure switches have inherent hysteresis (typically 0.2-0.5 bar). Consider this in control applications.

7. Installation:​ Use proper sealing (PTFE tape or sealant) on G1/4 threads. Avoid overtightening.

8. Maintenance:​ Periodically check pressure setting and contact operation. Clean the port if clogged.

Note: For complete installation guidelines, dimensional drawings, and detailed technical data, consult the official FESTO PEV Series Technical Manual. Always verify the exact model number configuration with the manufacturer, as notation variations may occur.
