Alsafe / Tetra Alsafe process control valves

Industrial Alsafe control valves including part numbers 6-3180124631 and 6-3180156241 engineered for metering and pressure management across processing lines. Tailored for Tetra Alsafe systems with replaceable trim, sanitary diaphragms and pneumatic actuators for continuous operation.

Accurate flow rate and line pressure modulation for ingredients and solutions
Component part numbers matching Tetra Pak designations 6-3180124631 and 6-3180156241
Interchangeable trim seats with linear and equal-percentage throttling profiles
Sanitary diaphragm barrier separating actuator mechanisms from the line media

Alsafe / Tetra Alsafe intermediate steam barriers

Intermediate steam barrier assemblies engineered to isolate the sterile buffer tank interior from upstream sterilizers and non-sterile piping. Maintaining culinary steam temperatures between 110 and 125 °C, the barrier prevents microbiological ingress along valve stems and flanges.

Continuous thermal steam barrier operating within 110 to 125 °C temperature limits
Enables independent tank sanitation without interrupting upstream UHT sterilizers
Automatic steam trap monitoring and condensate discharge across valve jackets
Thermal stem barrier design eliminating bacterial migration into sterile circuits

Alsafe / Tetra Alsafe low-fouling end valve clusters

Downstream end valve clusters featuring low-fouling internal geometry to curb product adhesion and sediment formation along filling feed lines. Smooth internal contours protect product taste, consistency and homogeneity during long sterile packaging runs without premature fouling.

Optimized flow profile eliminating dead zones, foul buildup and media degradation
Supports extended uninterrupted manufacturing operating campaigns up to 122 hours
Hermetic switching between storage buffer vessel and downstream filling machines
Preserves delicate flavor balance and emulsion homogeneity in dairy beverages

Alsafe / Tetra Alsafe CIP cleaning valves and sensors

Automated cleaning-in-place CIP and sanitization loops integrated with inductive conductivity sensors such as 90600-3924. Rapid phase transition monitoring distinguishes rinse water, caustic solutions, acid detergents and product, curtailing ingredient waste and water usage.

Sharp phase boundary detection between detergent solutions and pure rinse water
Full interface compatibility with conductivity sensor part number 90600-3924
Automated switching of recovery drain and recirculation routing valve clusters
Durable electrode assemblies withstanding aggressive hot acid and alkali cycles

Alsafe / Tetra Alsafe sterile air overpressure control

Sterile air regulating valve clusters managing gas headspace conditions within Alsafe / Tetra Alsafe buffering vessels. Maintaining continuous positive pressure over liquid media, the group averts tank vacuum during jacket cooling and blocks ingress of ambient contaminants.

Maintains a positive sterile air head blanket above the buffered liquid volume
Safeguards tank shell structure against negative pressure under rapid cooling
Sanitary pressure relief valves and breathable sterile micro-filtration venting
Differential pressure monitoring during dynamic tank filling and discharging steps

Engineering standards and valve matrix architecture in Tetra Alsafe systems

The modular valve clusters engineered for Tetra Alsafe processing systems route liquid food streams, sterile air and cleaning solutions with high hygiene integrity.

Built from AISI 316L stainless steel, every contact surface undergoes precision electro-polishing down to Ra < 0.8 μm to eliminate product adhesion and residue buildup.

All seat and modulating control valves incorporate spring-return pneumatic actuators paired with inductive stem position sensors for automated feedback.

The compact matrix arrangement combines routing, divert and drain valves onto a rigid skid frame, reducing overall pipeline length and eliminating stagnant dead legs.

Full internal flow sweep ensures thorough surface contact during CIP circulation, safeguarding against microbial accumulation and preserving product sterility during prolonged buffer storage.

Control valves 6-3180124631 and 6-3180156241: technical specifications and sizing

Sanitary control valves corresponding to part numbers 6-3180124631 and 6-3180156241 provide accurate flow regulation and backpressure control on Tetra Alsafe tank skids.

Engineered for sensitive dairy beverages, liquid ingredients and chemical dosing reagents, the valves employ a contoured elastomeric diaphragm seal that isolates the drive mechanism from the fluid stream.

A pneumatic positioner facilitates linear or equal-percentage throttling across varying operational flows.

During component sizing and replacement, engineering teams verify port dimensions, pipe connection standards (tri-clamp, welded or DIN coupling) and pneumatic signal inputs to guarantee flawless integration into existing plant control loops.

Intermediate steam barriers (ISB): thermal isolation and contamination prevention

The intermediate steam barrier (ISB) creates a dependable thermal isolation zone shielding sterile buffer volume from ambient plant environments and upstream utility piping.

Culinary dry steam at 110 to 125 °C continuously circulates through barrier cavities, neutralizing potential microbial ingress across dynamic stem seals and flange junctions.

An independent ISB manifold permits isolated CIP cleaning and chemical sanitization of the buffer tank while upstream UHT sterilizers continue undisturbed operation.

Jacket condensate drainage is governed by thermostatic steam traps, sustaining an uninterrupted thermal barrier throughout extended production runs.

Automated CIP/SIP sequences and inductive conductivity sensor integration

Automated cleaning-in-place (CIP) and steam sterilization (SIP) sequences across Tetra Alsafe systems rely on real-time fluid phase monitoring.

Inductive conductivity sensors, including sensor part number 90600-3924, are installed in the return flow header to instantly detect transitions between product, rinse water and caustic or acid detergent solutions.

The supervisory automation uses conductivity data to trigger return divert valves, directing reusable wash solutions back to storage tanks while routing diluted rinse water to drain.

This minimizes ingredient loss, shortens cleaning cycles and curbs overall consumption of fresh water and chemical cleaning agents.

Aseptic holding integrity and extended manufacturing campaigns up to 122 hours

Tetra Alsafe buffer vessels and sanitary valve groups maintain sterile holding conditions over continuous production runs lasting up to 122 hours.

This high operational reliability results from sterile air overpressure blankets in the tank dome and low-fouling end valve clusters positioned ahead of downstream packaging machinery.

Low-fouling geometry prevents product baking and sediment buildup in dead ends, protecting the taste and emulsion consistency of extended shelf life (ESL) dairy and juice products.

Slow-speed magnetic or top-mounted agitators provide gentle stirring, preventing separation in sedimentation-prone suspensions and particulate formulations.
