| Valves
We
have a wide range of valves offering port sizes from M5 G1/2"
which are
available with mechanical, manual, pneumatic and solenoid actuators.
Valves can be supplied free-standing or as part of a manifold with
or without the
D-Sub terminal system.
Construction
By
using high quality materials and an approved sealing system, we
offer distinct advantages to our customers.
No compromises were made in the selection of materials. The bodies
are made from anodised aluminium, the spools
from stainless steel and the manual overrides from brass. The major
advantage of this sealing concept is low friction.
This
advantage is based on the following technical features:
There
is no deformation of the seal during assembly. They are allowed
to move independently within the brass cage. Without air pressure
there is no contact pressure and, therefore, no friction. This construction
also has consequences for the seals of the valves in use. When switching
a 5/2 valve, only three of the five seals are exposed to pressure
and applying friction to the spool.
This
unique sealing design means that the contact pressure, and consequently
the sealing effect, increases proportionally to the air pressure.
If the air pressure is low, contact pressure of the seals and friction
are minimised.
Even
when pressure is high, due to the shape of the cage, there is only
the minimal contact pressure applied to the sealing rings which
is necessary to seal the valve, as shown in the drawing above.
These features offer you:
High
durability and extended lifetime!
High
flow combined with compact design!
High
reliability of the valves!
