A lock prevents unwanted changes to the controls. The airoperated 775 valve dispenses difficult, stringy materials. The valve body comes in all-stainless steel or aluminum with a PTFE-impregnated hard-anodized finish. Self-adjusting seals come in either a fluoroelastomer or PTFE. The valve’s shape, mounting configuration, location, and operation of the controls let the valve easily integrate into automated machinery or simple workstations. Available accessories include standard and custom nozzles, nozzle arrays, spray heads, and digital valve controllers.
