Product Description

We have gained immense admiration from our respected clients for manufacturing and supplying premium quality Fire Safe Ball Valves. These are specifically designed ball valves to bear large temperature. They have a second metal sheet for safety purpose. In case of fire, when soft-seat get melted, ball moves and touch downstream metal seat to form a leak-tight seal. We manufacture floating and Trunion types of Fire Safe Ball Valves. In floating ball design, sealing takes place by allowing ball under pressure to make tight seal. For higher pressure, trunion mounted valves are used.

Features:

Tight shutoff
No external leakage
Blow-out proof stem

Fire Safe Ball Valves

Carbon steel for general use.
Stainless steel for corrosive.
Alloy stell for low temp./high temp service.
Alloy 20, Hastelloy, monel for highly corrosive or abrasive application.
