Coilhose Pneumatics BLSV02F02F Relief Valve 150 Psi

Product Description

The COILHOSE PNEUMATICS BLSV02F02F is a brass-body relief valve designed to protect pneumatic systems from overpressure conditions. With a maximum rated pressure of 150 psi and a 1/8 inch FNPT inlet with MNPT outlet, this valve automatically vents excess pressure to keep downstream components within safe operating limits. The all-brass construction provides corrosion resistance and durability in compressed-air service environments. Licensed mechanical contractors and pneumatic system technicians install this type of valve as a safety device on air lines, compressor outlets, tanks, and pressure-regulated circuits.

This relief valve is suited for residential and light commercial pneumatic applications where a compact 1/8 inch ported safety valve is required. Typical installations include compressed air distribution systems, small air compressor setups, and pneumatic tool supply lines where overpressure protection is required by code or system design. The FNPT inlet and MNPT outlet configuration allows straightforward in-line installation with standard pipe fittings and thread sealant.

Key Features

• 150 psi maximum pressure rating for compressed-air overpressure protection
• 1/8 inch FNPT inlet and MNPT outlet for standard pipe thread connections
• Brass body construction for corrosion resistance in compressed-air service
• Compact form factor suitable for tight installation spaces
• Automatic pressure relief — no manual actuation required under normal operation

Compatibility

Designed as an OEM-style replacement or new-installation relief valve for pneumatic systems using standard 1/8 inch NPT pipe thread connections rated up to 150 psi.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Depressurize and isolate the air system completely before removing or installing any pressure-relief components. Apply thread sealant or PTFE tape to NPT threads per standard practice, taking care not to obstruct the valve inlet or outlet. Follow all applicable local codes and ASME guidelines governing pressure-relief device installation and inspection intervals.
