For Pilot-Type Solenoid
Valve Applications

Krytox™ fluoropolymer lubricants reduced damage
claims for a Korean valve manufacturer.
A 5-Port Pilot-Type Solenoid Valve Application

The ChallengeElectromagnetic force causes the spools inthe solenoid assembly to move to the left
and right, reciprocally (see Figure 1). The fast
movement creates friction. Pressure is gauged at
0.1–0.7 MPa (1–7.1 kgf), and the response time isless than 12–38 ms.

The valve manufacturer had the following
requirements:• Guarantee cycle operation of 3,000,000 for
one year• Resist water and oil that enter an air port fromother processes and attack the greases on thespools and seals, causing failure of the cycle• Must operate at room temperature andwithstand atmospheric pressure

The Solution

Benefits of Krytox™ Oils and Greases

High performance Krytox™ oils and greases stand up totough conditions. Applying Krytox™ oil to the solenoid
coil in the assembly helped to reduce the friction andheat, allowing for longer cycles. Coating the spools andseals with Krytox™ grease helped to extend the life ofthese components, while enabling them to resist theenvironmental effects of water and other oils.

Synthetic fluorinated lubricants from Chemours can also
be used successfully in other manufacturing applications.
These oils and greases are ideal for many conditions,such as:Success Factors• Water and oil resistance: immiscible with water or oil in
air and not subject to water wash-off• Continuous high temperatures up to 288 ºC (550 °F)• Use around hazardous chemicals• Plastics, elastomer, or metal applications• Where flammability is a concern, including reactivegases and oxygen service• Durability proven in a 3,000,000 operation cycle ofopening and closing• Compatibility with aluminum spool and EPDM spoolseal
