YUSV automatic unloading valve

The main purpose of unloading valve
This unloading type starting valve is applied to compressed air pipeline systems such as Roots blowers or screw blowers. When the blower is started, the conveyed gas flows into the outside through the unloading valve, and the blower starts with a slight load. At the same time, due to the pressure difference between the gas inside the pipeline and the outside atmosphere, the starting valve slowly closes, allowing the transported gas to flow into the normal working pipeline. The micro load start-up of blowers or other compressed gas supply equipment has been achieved, avoiding the impact on the equipment body, driving equipment, and transmission mechanism caused by direct load start-up. Pure mechanical structure, clever and reasonable design, reliable and fault free operation.

Main Features
Avoiding the hassle and malfunctions caused by using bypass, electric valves or actuators, and then controlling them by electrical control equipment.
The bypass, electric valve or actuator, and related control mechanisms have been eliminated, resulting in low system costs.
After installing a small pressure relief valve according to demand, it can replace the traditional pressure relief valve and better protect the gas source equipment. At the same time, it can play a role in maintaining constant pressure, better protecting equipment in harsh starting conditions.
Easy to install and maintain.
