Energy launches new flow control valve, high-pressure cylinder.
Energy Hydraulics has introduced its first-ever electronic flow control valve for the mobile hydraulic markets. Energy has manufactured a single-spool, monocast valve, but now has added a pressure compensated flow control valve.
The new valve is targeted primarily at applications such as fertilizer and salt spreaders, or any use requiring non-feedback ground speed control, horsepower control, speed rate control of motors, or speed control of cylinders. Three models are available with 15, 20 or 25 gpm flow ranges, with a listed repeatability of [+ or -]10 percent. The valves are pressure compensated in both ports and are electronically adjustable, and proportional from 1 to 12 Vd.c., with 24 V coils also available.
The valves can operate at pressures to 3000 psi maximum and can be used in both open or closed center hydraulic systems, as long as the control flow is always open and not blocked. The valves feature a hardened spool, SAE - 12 port sizes, with manual override standard.
Energy, Monticello, Iowa, has also introduced its first 3600 psi and first threaded and guide cylinder. The newly launched CHD cylinder line fits at the top end of the company's off-highway cylinder range and is targeted at medium- and heavy-duty construction equipment. The Energy CHD cylinder has either a threaded-in rod guide for bores from 1.5 in. to 5.5 in., or a threaded ring retainer beyond the guide for 6 in. through 10 in. bores.
The CHD cylinder has buttress threads for bores over 3.5 in., with a variety of seal packages available. The standard piston seal is a glass-filled Teflon glide ring, while the standard rod seal is an energized twin-lip u-cup with backup ring. Class 40 gray iron, ductile iron or steel piston and guide are available, with glass-filled nylon wear rings available as needed.
A variety of base and rod ends are available including a trunion mount, bolted-on valve block, and valve block in base end configurations.
