HydraForce expands electronic valve driver family
HydraForce has expanded its range of electrohydraulic controls with the addition of the configurable ECDR-0506A electronic valve driver. It can be used to enhance the control of hydraulic proportional valves used for transmission control, vehicle traction control, joystick control, and mobile equipment work functions, such as lifting, lowering, and rotating. The ECDR-0506A has a 32-bit […]
Linde Hydraulics launched modular valve system
Linde Hydraulics GmbH & Co. KG will be introducing its new VT1 Modular, a new modular valve system for mini-series and prototypes, at Bauma. The VT1 Modular system allows for up to seven user functions. Each function is controlled via a high-pressure directional spool valve, with possibilities to include secondary pressure and flow controls, all […]
Selecting directional control valves: From the basic to advanced
By Scott Knaack, Sr. VP of Sales and Marketing Prince Hydraulics Hydraulic directional control valves have always been fundamental to hydraulic circuits, machinery and equipment, but an increase in technology is bringing a new level of performance, sophistication and efficiency to these crucial workhorses. Today we see things such as fine metering spools, load sense, […]
Multi-function valve and pump controller
High Country Tek, Inc. has created a precision proportional controller that is rugged, versatile, compact, and simple to configure. Because of its programmatic flexibility, the EVC multi-function digital valve driver can be configured to control different machine subsystems, requiring only a simple configuration file for a range of functionality. And you don’t need to be […]
Directional control valves built with higher pressure capabilities
Muncie Power Products offers a family of directional control valves built with higher pressure capabilities to withstand the most extreme applications. Featuring high-grade iron castings and nickel-plated or hard chrome spools to meet high pressure applications, the family includes three series. Different spool, control, positioner and accessory options allow for customization of the V080, V130 […]
The lowdown on pressure-reducing valves
Pressure valves are absolutely critical for the safe, reliable and precise control of hydraulic machinery. As anyone would assume by their name, pressure valves are any hydraulic component put in charge of controlling and/or limiting fluid pressure. Although it is possible for a hydraulic system to operate without a pressure valve, nearly every machine has […]
New features for low-flow load-sensing valve
In an effort to meet new emissions and functional safety standards, system designers are turning to electrohydraulic solutions that offer more durable, efficient and reliable control. The PVG 16 is the first Danfoss low-flow load-sensing valve with electrohydraulic actuator technology — the PVE Series 6. Incorporating a microcontroller for closed loop spool position control, the […]
Pressure control: Upstream and downstream
By Carl Dyke, Hydraulics Consultant at CD Industrial Group Inc. www.cdiginc.com “It’s a PRV … a pressure control valve … a pressure regulator.” That’s what I sometimes hear when discussing symbols on a hydraulic schematic, or even when examining components. The acronym PRV really drives me crazy because it could stand for pressure relief valve […]
What is a Hydraulic Valve?
Asking “what is a hydraulic valve?” is like asking “how long is a piece of string?” The variations available to the hydraulic designer are absolutely astounding, not only because of the myriad types of valves on the market, but also because of the numerous manufacturers making them. The most basic description of a valve is […]
