Advantages:
->One Piece
ball and stem PFA Lined full port, Blow-out proof
->The lining of
valve and ball can provide the general chemical corrosion-resistance
materials
as
PFA & FEP by requirements.
->As for the
innovative plate-type PTFE bellows filling structure, it can automatically
adjust between
the
movable filling gland ring and spring tableting, and even though under the
condition of heat-cool cycle,
the
filling always has high leak tightness and reliability for
pre-selection loading.
->Even though on
condition of frequent alternation between coldness and heat.
it can realize the sealing effect for the flange of metal to metal
mode.
->It has
unified lining thickness in the sealing area to promote the ability for
resisting the permeable media
->Strengthen
the surface loading ability for labyrinth sealing through casting sealing lip.
Carry long life
PTFE
valve seat.
->It adopts
special spring valve seat design to ensure permanent leak tightness within the
range of the
entire pressure/temperature, including in condition of vacuum.
->It can choose
the lining with antistatic property.
->PFA and FEP
thermo-plastic valve lining with 3.5 mm's thickness, anti-seep, anti-corrosion
and anti-vacuum.
->As for the
high penetrability medium, it can adopt 5mms lining for the over-current part
in the valve.
