XCMG Air Compressor Special Valve (Unloader/Discharge) – OEM Ref. 800787141 / DL1113A

Name: XCMG Air Compressor Special Valve (Unloader/Discharge) – OEM Ref. 800787141 / DL1113A
Brand: GLOBALMACHEX
Availability: InStock
Rating: 5 (1 reviews)

This Air Compressor Valve Assembly (PN 800787141 / Model DL1113A) is a precision-engineered pneumatic component designed for XCMG air compressors used in brake and pneumatic systems. Whether functioning as an unloader, discharge, or relief valve within the compressor head, it regulates pressurized airflow and prevents over-pressurization or backflow that can damage the pump, air dryer, or brake actuators. Manufactured with CNC-machined valve seats and a calibrated stainless-steel spring housed in a brass or hardened alloy steel body, it delivers consistent cracking pressure, positive sealing, and rapid response under continuous duty cycles. Direct OEM replacement—no thread adapters or gasket modifications required.

Trade Information

This Air Compressor Valve Assembly (PN 800787141 / Model DL1113A) is a critical flow-control component purpose-built for XCMG air compressors serving the machine's brake and auxiliary pneumatic circuits. Functioning as an unloader, discharge, or pressure-relief element within the compressor head, it governs the timing and direction of pressurized airflow while preventing dangerous over-pressurization or reverse flow that can lead to pump damage, air dryer failure, or compromised braking performance. The valve body is machined from high-strength alloy steel or brass with precision-lapped seating surfaces, paired with a heat-treated stainless-steel spring calibrated to the exact OEM cracking pressure—ensuring consistent opening/closing behavior across millions of cycles. Each unit is individually bench-tested for leak-tightness and pressure-holding capability before shipment, and ships ready to install with standard OEM gasket interfaces—no custom adapters, thread sealants, or port modifications needed. Replacing a sticking or leaking valve at the first sign of slow pressure build-up or audible air loss restores proper compressor efficiency, protects downstream air-system components, and keeps your XCMG equipment's brake system operating safely within design parameters.
