Información del artículo

Parker’s selection of 3-position, 4-way proportional directional control valves provide predictable and precise controls for applications that require bidirectional flow and controllability. These valves are capable of handling flows up to 32 lpm (8.5 gpm) and pressures as high as 350 bar (5000 psi). These valves can be used in conjunction with an external compensator finer control is required, however these valves are ideal for variable flow actuator or motor applications that need exact control with to ability to stop completely and an acceptable rate of leakage due to the inherent characteristic spool design. Parker’s 3-position, 4-way proportional directional control valves can pair 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
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile

Features/Benefits:
• One piece cartridge housing
• Regulates flow proportionally to input solenoid current
• All external parts zinc plated

Applications:
• Applications requiring precise controls
• Variable flow applications
• Actuator control
• Motor speed control

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