Pressure Compensated Proportional Poppet Valves

Parker’s selection of 2-way proportional poppet valves provide exact and reliable controls for applications that require a proportional flow control with a very low leakage rate. These valves are capable of handling flows up to 83 lpm (22 gpm) and pressures as high as 210 bar (3000 psi). The added feature of an integrated pressure compensator make these valves ideal for applications that need controllability at a very high degree of confidence. Parker’s 2-way proportional poppet valves are available in normally-open or normally-closed configurations and can pair with any Current Controlled Pulse Width Modulation (PWM) valve driver. These valves have uses on a variety of machinery within the agriculture, aerial, material handling, or construction markets.

Markets:
• Agriculture
• Aerial
• Construction
• Material Handling
• Miscellaneous Mobile

Features/Benefits:
• Excellent metering capability and control throughout the full flow range
• Reduced drift
• Low leak control (less than 5 dpm)
• Modular solution to applied problem
• Low leak compensator, requiring no additional seals, results in very low hysteresis (< 10%)
• Maintains constant flow regardless of load condition
• Patented integrated low leak compensator

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

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