AIR RELEASE VALVE, ISOLATING VALVE<Mede of PDCPD>
Features-Light weight and compact synthetic resin quick air release valve withadequate measures to deal with foreign substance.
Excellent cut off performance at low pressure (4.9KPa).
Discharges air at a high rate and reduces the time for water
filling/release.
The isolating valve is equipped with a pressure gauge mounting tap as
standard (75 - 200 mm).
