FieldQ Valve Actuator
Corrosion Protection
Description
The corrosion protection system of FieldQ actuators consist of
the following treatments or materials:
1.
Pretreatment
The actuator housings are anodized inside and outside, to give
them a durable and superb protection against wear and corro-
sion.
2.
De-greasing.
All aluminum parts are de-greased before the coating is
applied by washing with an alkaline solution to assure the best
bonding between the aluminum surface and the coating.
3.
Finish
3.1 Actuator
- Polyurethane powder coating for exterior use.
- The powder coating is applied cold using automatic electro-
static spray equipment and is cured for about 10 minutes at
minimum 200°C (392°F) offering excellent light and weather
resistance.
3.2 Module
- Polyurethane coating for exterior use.
- The coating offers excellent light and weather resistance.
- Good chemical resistance against most bases, acids,
solvents, alkalis and oils at normal temperatures.
- Excellent exterior mechanical durability.
4.
High grade & hard anodized aluminum pinion.
Actuators with high grade & hard anodized aluminum pinions,
passed a 1000 hours salt spray test.
5.
Stainless steel or coated steel parts.
External parts are stainless steel or coated alloy steel.
6.
Corrosion protected springs on Spring Return actuators
All the springs of spring return actuator are Deltatone® or epoxy
(black) coated to prevent the corrosion of the springs and assure
a long cycle life.
