Expro Technologies is a leading explosion isolation valve manufacturers in Mumbai, suppliers, traders, dealers and exporters in Mumbai, We are offering the new designed explosion isolation valve.
This explosion isolation valve is a safety device and designed to preventing the propagation of explosion and pressure from one area to another area. It also minimizes the risk of secondary damage. It acts as a mechanical barrier and closes quickly to isolate the affected areas. It is dual functional aspects such as active isolation and passive isolation and these are used as per the requirement and situation. Let’s check out its different types, it’s using benefits and applications also!

Types of Explosion Isolation Valve
Being the best explosion isolation valve manufacturers and suppliers in Mumbai, we are providing the high-quality of explosion isolation valve such as:
- Active Mechanical Explosion Isolation Valve: These are the highly demanding and new technological mechanism of active isolation valve and requires internal sensors and external sensors and activation systems to close upon detecting an explosion accurately. It is more responsive and precise than passive systems. These relate to new sensors such as flame, pressure and heat resistance for rapid activation and it can be pneumatically, electrically, or hydraulically actuated.
- Passive Mechanical Explosion Valve: These new passive isolation valve can ablet to detect the abnormalities or external threat accurately such as explosion, stopping the flames and pressure wave from spreading further. It requires no external power or sensors to activate, relying purely on pressure dynamics. In the case of emergency, it reacts quickly and instantly to pressure waves caused by explosions. It contains a spring-loaded or flap mechanism that shuts off airflow.
- Double Flap Valve: This new designed double flap valve consists of two sequential flaps that prevent explosion backflow in dust collection systems and air ducts. These valves operate in both normal and explosion conditions. It has two types of independent and sequentially closing flaps for creasing a barrier against explosion propagation and allows for normal materials to flow under standard conditions. Due to this working procedure, these are used in the dust collection, pneumatic conveying, and material handling systems.
- Isolation Ball Valve: This isolation ball valve is majorly used in the large industrial sectors due to its higher performance, full-bore shutoff valve that provides explosion isolation by rotating a solid ball to block the flow of gases or dust-laden it. These relate to rotating ball mechanism and provides a complete seal when closed and it can be manually or automatically actuated. Due to its working procedure, these are used in pipelines and gas distribution networks.
