| Digital proportional valve driver comes in a wide variety of configurations and is compatible with all makes of proportional valves. |
The newest version of its Digital Display Proportional Valve Driver was recently introduced by Lynch Fluid Controls Inc., Mississauga, Ont., Canada. This new generation of proportional valve driver features an expanded digital display and hardware changes that improve 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.
Flexibility — The Digital Display Proportional Valve Driver comes in a variety of configurations:
• single solenoid mount with PG9 cable gland rated to IP 65,
• single solenoid mount with IP-65 rated DIN43650 cable connector,
• single or dual NEMA 4X enclosure with clear lid, and
• single or dual DIN rail mount open PCB.
Parameters can be customized to meet operational requirements. Operating voltage ranges from 9 to 36 Vdc. Command input can be set at 0-5 or 0-10 V, or 4-20 mA for a single and dual solenoid system. Additionally, the dual drivers can be set from -10 to 10 V. Current output ranges can be set from 0.20-3.00 A. Ramp time ranges from 0-99.5 sec.
Precision — The 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 450 Hz.
User friendliness — 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.
The 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° C.
