Parker's 3-position, 3-way open center spool type inverse 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, however the integrated check valves allow flow from the opposite port from the higher pressure to the lower pressure port, making them ideal for certain sensing or sequencing applications. These are used primarily to select between two accumulators to ensure the accumulator with the lowest pressure is charged.
Markets:
• Aerial
• Construction Equipment
• Forestry Equipment
• Material Handling Equipment
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile
Features/Benefits:
• Used to ensure that in a dual accumulator charging circuit the accumulator with the lowest pressure is sensed back to the charging valve
• Suitable for charge rates up to 25 LPM (7 GPM) per accumulator
• One size valve for most applications
• Ball type construction for low leakage
• All external parts zinc plated
Applications:
• Powered Brakes accumulator charging
Additional Technical Insight:
Used in conjunction with an accumulator charging valve this valve will ensure the accumulator with the lowest charge is sensed back to the charging valve.
