Lynch Fluid Controls Inc. has launched the newest version of its Digital Display Proportional Valve Driver. This new generation of proportional valve driver features an expanded digital display and hardware changes that increase performance and allow for future advances. According to Ernie Lynch, president and CEO, “Companies have had to stock different types of valve drivers for different command input types, but the universality of Lynch’s new proportional valve driver (DDPDX) eliminates this problem.”
The Lynch Driver is compatible with all makes of proportional valves.
The Digital Display Proportional Valve Driver comes in six different forms:
• single solenoid mount with PG9 cable gland with an IP 65 rating
• single solenoid mount with DIN43650 cable connector with an IP 65 rating
• single NEMA 4X enclosure with clear lid
• dual NEMA 4X enclosure with clear lid
• single DIN rail mount open PCB
• dual DIN rail mount open PCB
Parameters can be customized to meet operational requirements. The operating voltage ranges from 9 to 36 V DC. Command input can be set from 0 to 5V, 0 to 10V, 4 to 20mA for a single and dual solenoid system. In addition, the dual drivers can be set to ‐10V to +10V. Current output ranges can be set from 0.20 to 3.00A and ramp time ranges from 0 to 99.5 seconds.
The extra bright digital display increases situational awareness and eliminates uncertainty by letting the operator know that power is present, settings are accurate and input/output is correct in even the most challenging low light conditions. The dual solenoid driver features a four-digit display and the single solenoid driver has a three-digit display. The dither ranges from 40 to 450Hz.
This unique driver simplifies set up and monitoring procedures of proportional valves in open loop systems. No additional electrical equipment or software are required and parameter settings are saved in memory. In order to set the parameters of the driver, a simple tool like a screwdriver can be used to operate the encoders. Each driver comes with short circuit reverse polarity protection and command input over‐current protection.
The DDPDX also simplifies inventory and supply management. Having a proportional valve driver that is flexible enough to work with any command input type reduces inventory and supply management costs. Setup costs are also minimized because there is no need to invest in additional equipment to make the DDPDX operational.
These drivers are designed to be used in a variety of applications and built to withstand an array of harsh environmental conditions. The DDPDX is capable of operating in temperatures that range from ‐40 to 75 degrees C. Lynch’s drivers have found their way into adverse applications in 35 countries where they are currently being used in both mobile and industrial equipment.
