Safety Warning

Full Product Description

Parker’s family of pressure compensator valves feature a robust and contamination tolerant design that ensures consistent flow regardless of up or down stream pressures. These valves can operate with hydraulic system flows as high as 150 lpm and pressures up to 245 bar with a variety of differential pressure setting options. Parker’s pressure compensator valves are ideal for constant and consistent flow applications such as conveyors or saws within mobile, industrial, or manufacturing markets.

Markets:
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile

Features/Benefits:
• Stable and quiet response
• Contamination tolerant
• Hardened working parts for maximum durability
• All external parts zinc plated

Applications:
• Conveyors
• Saws
• Constant and consistent flow applications

Additional Technical Insight:
Inlet flow (upstream of the orifice or flow control valve) is split with one portion going to the compensator port inlet, the other portion passes through the orifice, or flow control valve, to the supply port. As pressure drop across the orifice reaches the selected compensator pressure drop, the higher pressure (pre-orifice) starts to shift the compensator spool into a throttling position. The valve works to maintain a constant pressure drop across the orifice. Using this type of valve allows greater flexibility in design and flows as these valves can flow as much as 40 gallons per minute. Compensator valves are used in circuits where a constant flow is desired regardless of upstream or downstream loads. As the pressure downstream of the compensator increases, the valve is forced open to maintain the constant pressure drop across the fixed, or adjustable, orifice. Conversely, if the pressure increases upstream of the orifice, the compensator valve will be forced closed to maintain the constant pressure drop across the orifice.
