Unique SSV Aseptic
This air-operated seat valve features the positive action of either a short-stroke or long-stroke actuator. The 761 valve is ideal for high volume, sanitary liquid processing applications. Its heavy-duty construction and precision-molded bonnet gaskets ensure positive alignment under severe operating conditions. The 761 valve has a sanitary and flexible design allowing it to be used in a wide range of applications, e.g. as a stop valve with two or three ports or as divert valve with three to five ports.
The valve is remote-controlled by means of compressed air. It has few and simple moveable parts which results in a very reliable valve.
The 761 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. The valve stem design requires only a single o-ring seal.
And bushings at each end of the actuator cylinder support stem also ensure perfect alignment.
The 761 series features a heavy-duty bonnet and body ferrule design that will stand up to years of pounding from hydraulic shock. Standard 32Ra finish on the ID.
