China Dn25 Sanitary Pressure Relief Valves with Union Type Check Valve

Safety Valve

Relieve excess pressure

Pressure can build inside vessels or systems due to blocked discharge, thermal expansion, chemical reactions, or a combination of these events. The Safety Valve is designed to flexibly relieve excess pressure from vessels or equipment at all times and under any circumstances. As the last and vital component in accident prevention, a high-quality, hygienic safety valve is an essential part of your operations.
Reliable protection

In a potentially dangerous situation, the Safety Valve is designed to open at a predetermined set pressure. The compressed spring force, which keeps the valve closed below the set pressure, is forced open when pressure builds up at the inlet of the safety valve. As these forces balance out, the valve will discharge and decrease pressure, ultimately reclosing as the system returns to normal.

Operating principle

The closing force in the Safety Valve is applied by a compressed spring with a set pressure greater than the operating pressure.

In a potentially dangerous situation, the valve will open at the predetermined set pressure. The spring force acts in the closing direction and the force created by the pressure at the inlet of the safety valve acts in the opening direction. At a certain point, these forces will be balanced out and the valve will make an initial discharge to relieve the pressure.
