Shuttle
LM • Hardened, precision ground parts for durability
• Internal mechanical stop limits poppet travel eliminating
spring solidification
• Spherical poppets for low leakage
Load/Motor
Controls
FC • “D”-Ring eliminates backup rings
• All external parts have yellow zinc dichromate. This (2) (1)
coating is ideal for salt spray applications. (2)
• High flow capacity
