  • Brazing three copper tubes to create a four-way valve [IH]
    Due to the use of a higher power system, speed expectations were exceeded and improved over the client's previous method, which was torch heating...

  • The basics of pneumatic control valves
    to the actuator. The actuator is connected to the exhaust passage, therefore spring force or gravity must return the rod to its original position. Three-way valves may also be used in pairs to operate a doubleacting cylinder, thus replacing a four-way valve. Consider using paired three-way valves instead
  • Proportional Valves
    are an inexpensive way to control position, velocity, or force on equipment requiring high-speed response at high flow rates. Many proportional valves are modified versions of four-way, on/off solenoid valves in which proportional solenoids replace conventional solenoids. In operation, solenoid force is balanced
  • Right-sizing pneumatic valves
    the valve's internal pathways connect. The four main functions for directional-control valves are 2/2 (two-port, two-way), 3/2, 5/2, and 5/3. have a pressure-supply port and a working port, and are either normally closed (NC) or normally open (NO). In an NC valve, the ports do not connect and permit flow
  • Digital valves raise machine performance, not cost
    a general trenching speed, as well as modes 30% faster and 20% slower for high-speed or precision work. An auto-idle feature enhances fuel efficiency and reduces noise. Two joysticks replace pilot controls, and hydraulic and electronic sensors enhance diagnostics. The Incova distributed valve has four
  • Intensifiers
    . Single-ram boosters are limited in their capacity to supply high-pressure oil. Therefore, only certain types of hydraulic valves can be used in air-to-oil booster circuits. Valves that have tank drainbacks should be avoided, because they use booster capacity during operation. Four-way hydraulic valves
  • Software Animates And Analyzes Fluid-Power Curcuits
    for pressure-control devices. The library shows at least four, any of which can be dragged and dropped onto the diagram. Calculation sheets make it easy to size just about every fluid-power component. To size a cylinder, users type in only a few of the characteristics and the software calculates the rest. During
