Parker Launches PE06 Proportional Valve for Brake-by-Wire Systems

Features and benefits of the PE06 proportional pressure reducing valve include:

• providing fast, precise hydraulic pressure control for electric/electrohydraulic braking
• low internal leakage rate of <25 cc at 200 bar
• inlet pressure maximum of 250 bar  and control pressure up to 170 bar
• flow rate of 301/min (pressure-dependent)
• single or dual-circuit design available
• robust design to withstand use in harsh operating conditions
• low hysteresis to ensure consistent braking force and reduced component wear
• solenoid connection AMP Junior Timer and DT04-2P “Deutsch” are now available with an integrated suppressor diode (optional) for serial quantities upon request

Per the company, brake-by-wire is an increasingly common technology particularly for off-highway vehicles. It replaces mechanical links with electronic signals to improve safety, efficiency, braking response time, and design flexibility. By providing a redundant architecture of the braking systems, it reduces the risk of catastrophic failures in cases of nonperformance of one circuit or electronic path. Because of these aspects, brake-by-wire and other by-wire technologies are critical to enabling autonomous and automated vehicle control.

Read our interview with Parker Hannifin’s Tim LaCrosse  in the article “Digitalization and Software Control Among Tech Trends at CONEXPO” to learn more about the growing use of steer- and brake-by-wire technologies the company sees in the mobile equipment market.

Brake-by-wire also helps to reduce the number of hydraulic components required, meeting the heavy equipment industry’s trend toward creating hydraulic-free cabins according to Parker Hannifin. Removing the hydraulics reduces weight and space claim as well as noise, heat and production time for cab manufacturers and OEMs.
