Parker's 3-position, 3-way spool type open center shuttle valves can handle flows up to 100 lpm (26 gpm) and 420 bar (6000 psi) while providing precise flow control for sequencing or pressuring sensing applications within various mobile or industrial markets. These spring centered valves use internal pilot signals to shift when pressure at either end of the spool exceeds the spring setting, allowing flow from the higher pressure port to the lower pressure port, making them ideal for sensing or sequencing applications.
Markets:
• Aerial
• Construction Equipment
• Forestry Equipment
• Material Handling Equipment
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile
Features/Benefits:
• High flow capacity
• Various switching pressures available
• Hardened working parts for maximum durability
• All external parts zinc plated
Applications:
• Transmissions, hot oil shuttle
• Sequencing
Additional Technical Insight:
Available in two sizes, these valves are generally used in a transmission circuit where the excess charge pump flow is directed to a cooler. This valve will be selected by the drive side and direct the excess flow from the return side to tank.
