Williams 112299 WM333S Compensating Dual/Single Valve
The most significant design of the WM317 or WM333 Compensating Valve is the fingertip control. An operator need not have a sore arm to complete a day's work. Adjustable handle friction may be set to the requirement of the job, or the desire of the operator. The low reactionary pressure (a function of exclusive Williams valving) allows precise control with small effort. Long life of individual parts is a result of the low reactionary valving. There are also no cams to wear out, as the operating force is straight push or pull. Pressure compensation range is variable from 0-60 PSI to 0-180 PSI, depending on the valve specified. This allows a wide choice for specific requirements. Compact mounting is a bonus feature to save space in critical panel areas, and all lines point straight down. A common air supply feeds both valves, and an air strainer is included with the fittings. Cartridge replacement of valving keeps unproductive time to a minimum. A removable barrier plate assembly renews the internal valving in minutes with simple hand tools. Air flow capacity is ample for all pilot controlled systems, and many direct hookups. One quarter inch cylinder parts flow over 35 CFM (standard air is measured at 100 PSI head pressure).
