Multiquip 0126004005 Valve Check - OEM Replacement Part for Air Compressors

The check valve prevents compressed air from flowing backward through the compressor system, protecting the screw-type rotary air end and maintaining system pressure when the unit cycles off. This critical component ensures your compressor builds pressure efficiently and prevents damaging reverse flow that can compromise the air end and discharge system.

Engineered specifically for Multiquip's 90-260 CFM screw compressor lineup, this OEM check valve maintains the precise tolerances required for optimal performance in demanding jobsite conditions. The valve works in conjunction with the air outlet system to regulate discharge pressure and protect internal components during startup and shutdown cycles.

Compatible with the following Multiquip air compressor models:

• DIS100SSK4F
• DIS185SSI4F
