Types of Blast Valve and Their Uses

Blast Valve

Safety is of prime importance in industrial settings where explosions or sudden pressure surges are a common scenario. And that’s where blast valves come into the picture. These valves act as a barrier between the explosion and the rest of the facility, containing the damage and limiting the impact on life and property. In this blog, we will dive deep into different types of blast valves and their uses to help you gain a better understanding of their importance.

Types of Blast Valve:

High-performance Blast Valves – 

High-performance blast valves can withstand high pressures and are designed to protect all types of equipment from blast waves coming from any direction. In addition, these valves also ensure that the pressure accumulation is relieved, reducing the risk of damage from an explosion. They are commonly used in refineries, chemical plants and construction sites involving heavy machinery.

Inline Blast Valves – 

Inline blast valves are located next to the equipment or machinery that needs protection from an explosion. They are designed to respond quickly to abrupt pressure changes, shutting off the flow of the material or gas that could cause an explosion. These valves are mostly used in pipeline systems.

Flap Valves –

Flap valves are designed for applications where large amounts of air or gas, such as an explosion, must be released quickly. They open in the direction of the flow of the material and close back when the pressure subsides. They are mostly used in large ventilation systems.

Explosion Isolation Valves –

Explosion isolation valves are designed to control a potential fire or explosion before it has a chance to spread throughout the facility. These valves quickly isolate and block the flow of the material or gas that feeds the fire or explosion, ensuring that the event remains confined to a small area. They are used in applications such as fuel storage and chemical plants.

Diaphragm Valves – 

Diaphragm valves are designed to handle fluids, gases, and other materials. They have a flexible diaphragm that separates the chamber that holds the material from the valve body. These valves are commonly used in industries that involve chemicals, pharmaceuticals, and biotechnology.


Understanding different types of blast valves and their uses is essential in ensuring the industrial facility is secured from potential explosions. Choosing the right type of valve for the specific application is critical, which can reduce the risks of injury and property damage. Different valves are designed to handle different materials and conditions, so it’s important to consult an expert to choose the right valve for your facility. Always make safety your top priority.
