Passive explosion-proof isolation valve VENTEX ESI-E/- D Type 6
Passive explosion-proof isolation valve VENTEX ESI-E/- D Type 6
The passive explosion-proof isolation valve VENTEX ESI-E/- D Type 6 is used in industrial container equipment such as silos, filters, cyclone separators, mixers, and dryers, which typically contain flammable substances that can reach explosive concentration ranges. If ignition sources are inevitably generated in these containers, there will be an explosion hazard.

The explosion isolation system can ensure that the detonation energy does not spread to other associated equipment.

Working principle: Under normal circumstances, the E-type (unidirectional explosion-proof) and D-type (bidirectional explosion-proof) valve cores are suspended in the middle of the valve by coaxial springs, while the C-type is equivalent to a check valve, which is opened by gas pressure. When the medium does not flow, the valve is closed, but it will not be locked.

When detonation occurs, the detonation pressure wave rapidly presses the valve core against the valve seat, thereby closing the valve and locking it through a mechanical mechanism. Resetting the locking device can reopen the valve.

characteristic:

1. Different selection allows explosion-proof isolation valves to be installed on horizontal or vertical pipelines;

2. The direction of explosion-proof can be unidirectional or bidirectional; It can also flow in the same or opposite direction as the medium;

If a venting system is installed on the device, please confirm that the triggering pressure of the venting device exceeds 50mBAR（ 200mBAR@DN600 )

Technical specifications:

1. Nominal caliber: DN100-DN600

2. Large medium flow rate: 20m/s, (optional 25m/s)

3. Intrinsic safety type;
