Sanitary Hygienic Butterfly Valve Tri Clamp Pneumatic Valves

Manual isolation in hygienic process lines requires repeatable disc positioning, compatible sealing materials, and a suitable pipe connection. A three-piece welded butterfly valve with a 12-position handle provides controlled manual adjustment, while CNC-machined stainless steel components support consistent assembly.

Three Piece Body Access Around the Disc

The three-piece body separates the main valve sections around the disc and seat. This arrangement gives access to internal components during maintenance without replacing the complete valve assembly.

For a sanitary butterfly valve, this structure suits fixed process sections where inspection or service requires access to the valve body.

Twelve Positions for Repeatable Adjustment

The 12-position handle provides indexed disc positioning across the operating range. It allows repeatable intermediate settings instead of limiting operation to fully open or fully closed.

A manual handle suits local control points with limited cycling. Pneumatic sanitary valves are more suitable where remote actuation or repeated automated operation is required.

• Repeatable intermediate disc positioning
• Direct local manual control
• Suitable for limited operating cycles
• Optional pneumatic actuation

Welded Ends Versus Clamp Access

Welded ends create a permanent connection with the surrounding pipe and suit fixed sections where valve removal is infrequent.

A tri clamp butterfly valve uses a removable connection for locations that require regular inspection, cleaning, or replacement. The connection should match the piping layout and service method.

Seat Selection for Process Media

Hygienic butterfly valves require seat materials compatible with the process medium and cleaning cycle. Available choices include EPDM, silicone, NBR, and FKM, each with different resistance to chemicals and temperature.

The operating temperature is specified at -20°C to 120°C. Pressure limits should be confirmed for the selected configuration because ratings can vary with operating conditions.

Design Details and Their Process Role

Where the Valve Structure Fits

A sanitary butterfly valve can serve isolation points, process skids, equipment connections, and hygienic transfer lines. Manual operation fits local control, while pneumatic sanitary valves suit automated systems with repeated cycling.

Final configuration depends on the medium, seat material, pressure, temperature, connection type, cleaning method, and operating frequency.
