ARAG Relief & Manual Dump Valve with T5 fork coupling - 871T502

Take full control of your spray system with the ARAG 871T502 manual control valve with electric relief. Designed and manufactured in Italy by ARAG — one of the world's leading suppliers of sprayer components — this valve serves as the main on/off and pressure-regulating valve on self-propelled and trailed crop sprayers.

The 871T502 pairs a low-power 12V electric on/off actuator with an adjustable maximum-pressure relief valve. When the main valve is closed or the set pressure is exceeded, the relief valve automatically bypasses flow back to the tank, protecting the pump, hoses, and boom from over-pressure while maintaining a stable, consistent spraying pressure.

The valve body is fitted with a T5 fork connection for quick and secure integration into ARAG control units, and is available with your choice of inlet hosetail: 19 mm, 25 mm, 30 mm, or 32 mm, or 3/4″, 1″, or 1 1/4″ hose fittings.
