Pressure Compensated Priority Flow Control Valves

Onde Comprar

Pressure compensated priority flow control valves maintain constant flow regardless of changes to inlet pressure for flows up to 90 lpm (24 gpm) and pressures up to 420 bar (6000 psi); excess flow is diverted once the priority flow requirement is met.

Descrição completa do produto

Parker’s family of pressure compensated priority flow control valves feature a proven design that allows for a reliable and repeatable flow compensation curve throughout a wide pressure range while ensuring priority flow is met. These valves can operate with hydraulic system flows as high as 90 lpm and pressures up to 420 bar with a selection of adjustment and tamper-proof options. Parker’s pressure compensated priority flow control valves are ideal for steering, brake, or actuator control applications within a broad range of markets, such as the agriculture, construction, material handling, industrial, and oil & gas markets.

Markets:
• Agriculture
• Construction Equipment
• Material Handling Equipment
• Miscellaneous Industrial
• Miscellaneous Mobile
• Oil & Gas

Features/Benefits:
• Fine adjustments
• Reverse flow function
• Hardened working parts for maximum durability
• Tamperproof options available
• All external parts zinc plated

Applications:
• Steering applications
• Actuator speed control
• Meter-in circuits

Additional Technical Insight:
Priority style pressure compensator flow control valves maintain constant priority flow to one leg of a circuit regardless of any changes in load or inlet pressure. Once the priority flow is satisfied, any excess flow may be used in other parts of the circuit. The valve consists of a control orifice housed within a spring biased compensator spool. This orifice may be fixed or adjustable. The priority port is normally open while the bypass port is normally closed. As flow enters the inlet port of the cartridge, it passes through the control orifice. A pressure differential is created across the compensator spool. If the inlet flow exceeds the setting of the valve, the force produced by this pressure differential exceeds the spring force and shifts the compensator spool; opening up the bypass port, and bypassing the excess flow. If the load pressure at the bypass port is greater than the load pressure at the priority port, the compensator spool will further shift restricting the priority flow to that of the valve setting. However, caution should be taken if the priority gets blocked so that no flow can pass through the control orifice, the compensator spool will shift, blocking the bypass port and allowing inlet pressure to go to full system relief pressure. It is common to place an external relief valve downstream of the priority flow port to prevent a no flow condition.
