Description
We can manufacture a wide range of 3 way metal seated ball valve,
with “L” port or “T” port. The advanced solutions typical of SAT
model are used on these valves that still have no equal on the
market at present.
Our valves are equipped with metallic seats to allow the
manufacturing of metal seated ball valves with absolutely ZERO
LEAKAGE suitable for a wide range of services with working
temperatures from 100°C to +400°C.
The typical elastic properties ofeats and the fully bolted
construction allow an easy maintenance without necessity of
additional lapping of the seats against the ball.
The very high precision grounded balls are 100% controlled and they
are hard coated with most advanced system. All 3 way ball valve are
“trunnion mounted” in order to avoid lateral load against the
seats.
The 3 way valve is equipped with a unique and patented stem seal
design. The spring placed at stem top gives the contact load for
low pressure tightness and the adjustment of potential wearing.
The 3 way ball valve has a unique and patented stem tightness. The
spring located in the upper part of the stem provides the preload
for performance at low temperatures, recovering the wear.Cryogenic
or Non Trans Flow versions available on request.Live Loaded Design
stem packing.
