Midland Industries 87002 Safety Valve 125 Psi 1/4 in Mpt

Product Description

The MIDLAND INDUSTRIES 87002 is a brass-body safety valve rated for 125 psi and 120 cfm, designed to protect pneumatic systems and air compressors from overpressure conditions. The valve connects via a 1/4-18 male pipe thread (MPT) and provides automatic pressure relief when system pressure exceeds the set threshold. Its compact brass construction makes it suitable for air compressor installations where reliable overpressure protection is required. ASME-coded, this valve meets recognized standards for pressure relief in pneumatic service. The 87002 weighs 0.12 pounds and measures approximately 2.05 inches in length, 0.8 inches in width, and 0.7 inches in height.

The MIDLAND INDUSTRIES 87002 is used in pneumatic and compressed air systems, particularly as a compressor safety valve on small to mid-range air compressors in residential and light commercial settings. It is a direct-mount relief valve suited for installations where a 1/4-inch MPT port is available on the compressor tank or pressure line. Pneumatic technicians and maintenance professionals typically install this valve as part of routine compressor servicing or as an OEM-style replacement on equipment requiring a 125 psi relief rating.

Key Features

• Rated relief pressure of 125 psi for dependable overpressure protection
• 120 cfm flow rate supports adequate pressure venting under relief conditions
• 1/4-18 MPT connection for direct installation into standard pipe thread ports
• Brass body construction provides corrosion resistance in compressed air service
• ASME coded design meets recognized pressure relief standards
• Compact size and lightweight at 0.12 pounds for easy installation in tight spaces

Compatibility

Designed as an ASME-coded OEM-style replacement safety valve for pneumatic and compressed air systems requiring a 1/4-inch MPT connection and a 125 psi relief rating.

Installation Notes

Installation should be performed by a qualified technician with the compressor fully depressurized and power disconnected before removal of the existing valve. Apply thread sealant appropriate for compressed air service and tighten to standard pipe thread engagement without over-torquing the brass fitting. The valve must be installed in the correct flow orientation and must not be adjusted, plugged, or blocked after installation. Refer to applicable ASME and local pressure equipment codes for inspection and replacement intervals.
