ATR - Adjustable thermal relief valve 1/4" BSPP Hydronit

Hydronit ATR (SVRFH) is an adjustable thermal and anti-shock relief valve. It protects the circuit from high pressures caused by thermal expansion of the hydraulic fluid by relieving a few drops of fluid, and resets itself as soon as the trapped pressure decreases. The valve is mounted on the actuator side of the circuit when it is exposed to temperature variations.
