Detailed introduction

Patent No.: ZL201620182050.0
Dedicated to the stable high-pressure fire protection system for petrochemical enterprises

Scope of application:

Specialized products for the "Stable High-Pressure" firewater system in petrochemical enterprises

Product features:

● Structural Components: Self-draining freeze-proof valve assembly + manual foam monitor nozzle.
● Quick valve assembly operation: Simply rotate the wrench 4/5 of a turn to fully open or close.
● Piston-type drain valve automatically removes residual water from the cavity after the valve assembly closes, preventing freezing in winter.
● Can deliver a columnar jet or a misty spray.
● The main valve in the valve assembly seals against pressure— the greater the pressure, the better the seal.
● Made from premium materials, offering superior rust resistance.
● JOTUN paint, lasting three years without fading.
