Vacuum Negative Pressure Safety Valve

The vacuum negative pressure safety valve cooperating brand YOY Yongyi Valve Group designed by Dazhong Valve Group is the safety valve of Yongyi Valve Group. The main parameter of the vacuum negative pressure safety valve is the displacement. The height is different, and it is divided into two types: micro-opening type and full-opening type.

The main parameter of the vacuum negative pressure safety valve is the displacement, which is determined by the diameter of the valve seat and the opening height of the valve disc. According to the different opening heights, it is divided into two types: micro-opening type and full-opening type. .
A72W-10P/R vacuum negative pressure safety valve is suitable for negative pressure system with temperature ≤200℃. When the negative pressure in the container exceeds the allowable value, the vacuum negative pressure safety valve will automatically open and suck in air;
When the negative pressure in the container reaches the allowable value, the A72W-10P/R vacuum negative pressure safety valve will automatically close to protect the equipment and system.
This product is generally installed in a normal non-negative pressure system. When the discharge valve of the container and system is not opened and negative pressure is generated, the vacuum negative pressure safety valve will automatically open to protect the equipment from damage.
Applicable scope of urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection, vacuum devices
