|
|
|
Insensitive to contamination in the hydraulic fluid , to high temperatures and to high pressure surges
|
- Use instead of directional valves for "ad hoc" applications
- Controlling movements of inspection and test equipment
- For systems where pressure is to be built up or released in a targeted and metered manner
- Applications where pressures have to be maintained over a long period of time.
- Taper-seat design (hardened, ground parts)
- Any mounting position
