Flat gate valve with diversion hole
Technical Parameter
Product model: Z43W/F
Nominal diameter: DN40~600mm
Nominal pressure: PN1.6~25.0MPa
Operating temperature: -29°C~120°C

Product Structure Features
Flat gate valve with diversion hole has two kinds of structures, soild gate and expandng split gate. On the gate there is a through hole which is the same size as body passage. When the
valve is opened, the diversion hole on the gate constitutes a through conduit to the body bore, easy for medium to flow and pigs to clean,prevent medum depositing which affects
conveying capacity of the pipelines.
