Detailed introduction

Firefighting-specific for petrochemical enterprises

Scope of application:

Petrochemical companies use "steady-high-pressure" firewater or foam-water mixture pipelines to control water flow by means of shut-off and on/off valves.

Product features:

● Quick to open and close
● Reliable sealing
● Special treatment for superior corrosion resistance
● Simple and effortless operation
● Unique and practical design
