A completely different approach to packing is a device called a bellow seal. It is an accordion metal tube that is fastened to the valve stem and the bonnet, forming a leak proof seal with negligible friction. The accordion ribs give the bellow seal the ability to stretch and compress with a sliding stem’s linear motion. The port on the extended bonnet serves as a point of connection process fluid leak detection sensors, to sound an alarm and or take action in the event of a ruptured bellows.

Bellow Seal Safety Valve Manufacturer in USA has designed to compensate for the influences of back pressure or to protect the fluid entering the bonnet area and the possibility of going into the atmosphere. This type of valve is commonly used in critical applications where minor set pressure is required.
A safety Valve is a pressure relief valve that releases a medium from a boiler, pressure vessel, or another system. Their primary role is safety and is used for boiler over pressure protection, and process operation to prevent product damage due to excess pressure. The main function is to protect life, the environment, and property against the failure to control system pressures, and last it offers reducing system pressure before total failure.

Advantages of Bellow Seal Safety Valve:
 It is reliable
 Simple structure
 Easy to maintain
 Ensure no leakage of steam
