These valves provide a very cost effective
alternative to the more expensive valves manufactured
in exotic materials such as Hastalloy, Titanium etc.
One piece ball and stem ensures there is minimal play
between valve and actuator, giving precise and responsive
control. One piece PTFE bellows type packing is pre
loaded using a Stainless Steel spring gland follower
and ensures no leakage to atmosphere even during hot
and cold cycling. Valves are designed with optimum lining
thickness to ensure permeating media such as Chlorine
does not come into contact with the body. All products
are finished externally with a high quality epoxy paint.
Features and Benefits:
Cv range of .8 - 400
Equal percentage characteristic
Blow out proof stem
Double stuffing box for applications
requiring absolute safety
Tight Shut Off
Liners are anchored and suitable
for use on vacuum applications
Size Range: 15-100mm
Body Material: S G Iron
Trim material: PTFE, PFA, Hastalloy, Titanium
Lining Materials: PFA, FEP, PVDF
End Connections: Flanged
Pressure Rating: ANSI 150LB, BS4504 10/16
This range of control valves provides
the ideal solution for applications where highly corrosive
and aggressive fluids need to be controlled. The valve
has a ductile cast iron body epoxy coated with a range
of linings to suit the particular application. A standard
PTFE bellows provides protection from leakage to atmosphere
in the stem area. The plug and seat are made of modified
pure PTFE and are easliy replaced. Hastalloy and Titanium
seats and plugs are also available. Trim characteristics
- On/Off, Linear, Equal percentage. All bolts and nuts
are stainless steel providing protection against corrosion.
Available with the Valtek linear actuator as standard
but can be adapted to suit other actuator types on request.
Features and Benefits:
Wide range of Cv values
Micro flute plugs available for
handling small flow rates
Bellows sealed bonnet ensures no
media leakage to atmosphere
Cost effective when compared to
metal alloy equivalents
Tight Shut Off
Liners are anchored and suitable
for use on vacuum applications
