Detailed introduction

Patent No.: ZL201620182046.4

Scope of application:
Installed within process units of petrochemical enterprises: heating furnaces, Class A gas compressors, pumps and heat-exchanging equipment where the medium temperature exceeds its auto-ignition point, as well as near oil pump rooms shorter than 30 meters, in tank areas, and along both sides of critical roadways—these are designed for immediate self-rescue, fire suppression, or cooling purposes.

Product Features

● Structural Components: Self-draining freeze-proof valve assembly + outdoor rainproof pedestal-mounted cabinet and associated fire-fighting equipment.
● Quick valve assembly operation: The wrench needs to be turned just 4/5 of a rotation to fully open or close the valve.
● Piston-type drain valve automatically removes residual water from the cavity after the valve assembly closes, preventing freezing during winter.
● It can be sprayed at high flow rates using a water hose, or directed in concentrated bursts at low flow rates with a flexible hose and spray gun.
● The main valve in the valve assembly seals against pressure— the greater the pressure, the better the seal.
● Made from high-quality materials for each component, offering excellent corrosion resistance.
● JOTUN paint, lasting three years without fading.
