WAFER BALL VALVE
wafer ball valves are ideally suited to applications where space is
at a premium provide plus all the benefits of flanged ball valve
while reducing the cost and weight. The valve can be installed
between flanges with help of bolts.
Our wafer ball valve is normally one-piece design and floating ball
type, and are available in both cast and forged construction in
sizes ranging from DN15 to DN 100, in #150 to #900 pressure rating.
General Features
Italy Ball Valve
Applicable Standards:
- Design and Manufacturing : GB / T12237 / 1989
- Connection : JB / T79
- Fireproof Test: GB / T13927 - 1992

Wafer Type ball valves (or called “Italy Super Thin” Type ball
valves) are used in the pipeline equipment in the condition of
PN1.0~2.5MPa, working temperature of 29~180℃(sealing ring is RPTFE)
or 29~180℃(sealing ring is PPL Polyphenylene), to achieve to cut
off or connect the medium in the pipeline. The applicable medium,
such as water, steamer, oil, Nitric Acid, Acetic Acid, Carbamide,
or medium of oxidizability can be applied subject to difference
valve material adopted.
