Cartridge Spool Type Shuttle Valves with All Ports Closed

Parker's 3-position, 3-way spool type closed center shuttle valves are available in two cavity sizes and provide high performance pilot control; capable of flows up to 175 lpm (46 gpm) and 350 bar (5000 psi).

Полное описание продукта

Parker's 3-position, 3-way spool type closed center shuttle valves can handle flows up to 175 lpm (46 gpm) and 350 bar (5000 psi) while providing precise flow control for sequencing or pressuring sensing applications within various mobile or industrial markets. These spring centered valves will 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
• Compact cost effective design
• Various spring options 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.
