Peter Huber Ball Cock CPL, M16 x 1

The Peter Huber 328240 is a high-specification, 3-part manual ball valve assembly (Ball Cock CPL) designed for high-performance thermoregulation in demanding laboratory and pilot plant environments. Featuring a standard M16x1 thread, this industrial-grade valve is engineered to handle extreme thermal conditions, supporting an expansive working temperature range from -60°C up to +200°C. Constructed from premium 1.4404 (AISI 316L) stainless steel and featuring high-quality PTFE seals with separate chambers, it provides superior chemical resistance and a leak-proof shut-off. Its "blow-out proof" stem design and DN10 nominal width ensure safe and efficient fluid control, making it an essential component for isolating reactors or external applications in high-pressure circulation loops.

Key Features:

• Brand: Peter Huber
• Connection Type: M16x1 thread connection (standard for Huber laboratory circulators)
• Design: 3-part body construction, DN10 (10mm internal diameter)
• Temperature Range: Versatile operation from -60°C to +200°C
• Material: High-quality 1.4404 (316L) stainless steel for maximum durability and corrosion resistance
• Sealing: High-performance PTFE seals with specialized separate chamber design
• Pressure Rating: Rated for up to 10 bar at 175°C (Maximum safety margin)
• Safety: Features a blow-out proof steam-grade stem design for high-pressure industrial use

This ball valve is optimized for systems where thermal stability and personnel safety are paramount. Unlike standard low-temperature valves, the 328240 is built to withstand the rigors of frequent temperature cycling and high-pressure pumps. Its manual operation lever allows for quick, clear status identification, making it the perfect choice for process isolation in Ministat, KISS, and specialized CC series temperature control systems.

Frequently Asked Questions

1. How does the 328240 differ from the standard 6091 ball valve?
The 328240 is a heavy-duty, 3-part stainless steel valve rated for a much wider temperature range (-60°C to +200°C) and higher pressures (10 bar) compared to the 6091 model, which is typically restricted to 90°C or 140°C. It is designed for industrial-grade reliability.

2. Can this valve be used with cryogenic thermal fluids?
Yes. With a lower limit of -60°C, it is perfectly suited for use with silicone-based low-temperature fluids. The PTFE seals remain flexible and effective at these temperatures, preventing leaks in cold environments.

3. Why is the 3-part body design important?
The 3-part construction allows for easier maintenance and cleaning. If the seals eventually wear out after years of high-temperature use, the valve body can be serviced without necessarily removing the entire fitting from the pipework.

4. Is the M16x1 connection compatible with all Huber units?
M16x1 is the standard outlet size for Huber’s smaller and mid-sized units like the Ministat and KISS series. For larger Unistat models using M24 or M30 threads, you would need a thread adapter to use this specific valve.

5. What does "blow-out proof stem design" mean?
This is a safety feature where the stem (the rod connecting the handle to the ball) is installed from the inside. This prevents the stem from being ejected under high internal pressure, ensuring the safety of lab personnel during high-temperature operations.
