PARKER HANNIFIN DF201C60 - 2 Way Flow Control Proportional Valves

Parker’s selection of 2-way flow control proportional valves provide repeatable and precise controls to circuits requiring proportional flow control through a single line in a normally-open or normally-closed configuration. These valves are capable of handling flows up to 227 lpm (60 gpm) and pressures as high as 210 bar (3000 psi). These valves can achieve pseudo pressure compensation in both normally-open and normally-closed versions due to the pressure drop across the spool orifices, but an external compensator can also be used if finer control is required, making these valves ideal for variable applications that need exact control and do not demand the exact same flow every time a function is operated. Parker’s 2-way flow control proportional valves pair well with any Current Controlled Pulse Width Modulation (PWM) valve driver and can be used on a variety of mobile and industrial applications within the agriculture, construction, and manufacturing markets.

Markets:
• Agriculture
• Construction
• Material Handling
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile

Features/Benefits:
• Low hysteresis
• Hardened working parts for maximum durability
• All external parts zinc plated

Applications:
• Applications requiring precise controls
• Variable flow applications

Additional Technical Insight:
Recommended to be used with a Current Controlled Pulse Width Modulation (PWM) valve driver.
