STANDARD DESIGN

The Alfa Laval 700 Series valve's rugged plastic stem bushings eliminate metal-to-metal galling. The stem is threaded to the actuator shaft, eliminating the coupling between the stem and actuator, which ensures proper alignment. Bushings at each end of the cylinder support stem also ensure perfect alignment. Each 700 Series valve features a heavy-duty bonnet and body ferrule design that will stand up to years of pounding from hydraulic shock.

WORKING PRINCIPLE

700 Series valves are remotely controlled by means of compressed air. This design requires very few simple, movable parts, greatly enhancing reliability. Heavy-duty construction and precision-molded bonnet gaskets ensure positive alignment under severe operating conditions. The valve stem design requires only a single o-ring seal.
