700 Series
More dependability and easy maintenance
The 700 Series valves are designed to deliver years of reliable performance. Rugged and long-lasting plastic stem bushings eliminate metal-to-metal galling. The stems are threaded to the actuator shaft, eliminating the coupling between the stem and the actuator, thereby ensuring proper alignment. And bushings at each end of the cylinder support stem also ensure perfect alignment. The 700 Series features a heavy-duty bonnet and body ferrule design that will stand up to years of pounding from hydraulic shock.
More styles and sizes for more application versatility
Two actuators (long and short) fit most 700 Series valves – including a wide selection of shut-off and divert valves. Valves are also available in sizes from 1" (25mm) to 4" (102mm) OD so you can build any size valve without increasing inventory requirements. Available normally open or normally closed, actuators can be field-reversed simply by disassembling, repositioning and reassembling.
