In February, we celebrate 5 years of Präzisionsarmaturen.com – thank you for your trust, and we look forward to continuing to support you with high-quality precision valves, fast delivery routes, and solution-oriented service in the future.
In February, we celebrate our 5th anniversary – and above all, we would like to say one thing: Thank you. Thank you to our customers, partners, and suppliers who have supported us since the beginning and continue to make us better every day through their requirements, projects, and feedback.
We started as a young family business that, in February 2021, took over the customer base and manufacturers of an established company that had been successfully operating in the market for more than 40 years. Since then, we have consistently pursued one goal: high-quality precision valves, reliable availability, and service that truly makes a difference in everyday operations.
What sets us apart is the combination of manufacturer expertise, direct access to numerous sources, and a practical understanding of industrial applications. We are an authorized partner of leading manufacturers worldwide, including Saint-Gobain (fluoropolymer valves, high-purity components), Kofloc (flow controllers, nitrogen systems, laboratory technology), and Aerre Inox (stainless steel valves for pharma and biotech applications). Our portfolio is complemented by other well-known suppliers such as Tescom/Emerson, ChemTec, VERSA, Plast-O-Matic, iPolymer, and many more.
Our solutions cover a wide range of applications – from PTFE and PFA valves for semiconductor processes and aggressive media to OEM components for fluid transfer, industrial pressure regulators, EC79-compliant hydrogen valves, and FDA-compliant valves for the food industry.
One key factor for many of our customers is speed. Thanks to direct supply channels without intermediaries, delivery times and costs can often be reduced. At the same time, we also support complex or unusual inquiries – with research, experience, and a strong network until the right solution is found.
The trust we have earned over the past years reflects the success of this approach: our website lists approximately 240 customers and 25 suppliers, and we are proud to be involved in projects and applications alongside well-known companies such as Robert Bosch, Infineon, Continental, VW, and many others.
Behind everything are dedicated people: Josef (all-round specialist, IT entrepreneur since 1998; focused on the wholesale of precision valves since early 2021), Claudia (order processing), Tahnee (accounting), and Renate (customer service), with additional support in shipping during vacation periods.
We look forward to the years ahead – to challenging applications, new opportunities, and growing partnerships. If you have a project where precision, material resistance, or reliable control is critical: Contact us.
What, How, Where & Why:
Process Cooling Sticks
Supply Sticks
As the name implies, Supply Sticks are generally used on the supply side of a process cooling applications. Located between the pump and the cooling components, these "sticks" may feature any number of valves, instruments, and other process controls pre-assembled for the following benefits:
Benefits
Increase strength by eliminating nipples
Reduce piping footprint
Reduce installation connections and
Eliminate adapters
Eliminate multiple part numbers
Sticks are highly customizable. In most cases the supply stick is called on to reduce downstream pressure to the cooling system, provide shut-off for servicing the system, and report system pressure.
For these reasons, most supply sticks feature a pressure regulator, a ball valve, and a pressure gauge, along with a gauge guard to protect the instrument from corrosion.
Return Sticks
Like the supply stick, the return stick is generally used for process cooling applications. Placed after the cooling components in a system, it may feature any number of valves, instruments, and other controls.
In most cases the return stick is called on to verify flow, pressure and temperature, and control or "throttle" flow through the system. For these reasons, most feature a manual diaphragm valve, a flowmeter, and a pressure/temperature Tridicator.
Some users prefer a metering ball valve with a linear flow characterized ball in place of the diaphragm valve. This custom option provides extremely accurate and predictable flow rates with a simple twist of the wrist.

What Causes Air in Liquid Piping Systems:
Air gets into most piping systems three ways. First, it is there to begin with. Unless the piping system is entirely assembled in a vacuum chamber, it will naturally have atmospheric air. Filling the system will expel some of the air, but not all of it. Traces of the original start-up air remains trapped at high points in the system.
The second source of air enters mechanically. Air is fed in by pumps, drawn in through open valves, etc. And when the system has vacuum conditions, air sneaks through seals, leaks – any opportunity it can find. As Aristotle said, nature abhors a vacuum.
A third way air enters a system is by piggybacking on the liquid itself. In the average municipal water system, for example, entrained air represents about 2% of the total water volume. This air is then released through natural outgassing, and joins the rest of the air in the system’s high points.
To show just how much air this is, if the entrained air in a 100’ pipeline were to completely settle out of the liquid, it would represent a 2’ slug of air. Whether the 100’ pipe is ½” or 3” diameter, 2% still represents a 2’ slug. Now if it were 1,000’ of piping, you could conceivably have a 20’ foot slug of air! Add that to the pre-existing air, plus whatever entered through pumping, and you have the potential for a serious volume of air.
Air (or gas) in a liquid piping system tends to accumulate at elbows and high points during low flow or static conditions.
This air pocket impedes flow as the system operates.
The flow restriction reduces the efficiency and performance of the system, forcing the pump to work harder and line pressure to fluctuate.
Eventually the air pocket grows, pressure builds, and the air pocket is set in motion with potentially devastating impact.
What it does:
So there are pockets of air in the system… what’s the problem?
Air in a piping system tends to accumulate at high points during low flow or static conditions. As the flow rate increases the air can be forced along the pipeline by moving liquid, and may become lodged at extreme high points, where it reduces the area available for flow. These flow restrictions reduce the efficiency and performance of the system.
As an air pocket grows, the velocity moving past that point increases until eventually the air is swept on toward an outlet. While line restrictions are a problem, a more serious situation can occur when air is rapidly vented from the system under pressure. The result is similar to instantaneous valve closure: water hammer will occur, with pressure surges that can easily exceed the strength of the system.
This often results in damage to the system, to property, and it can be dangerous to personnel.
How to get rid of it:
One of the time-honored methods of releasing system air is to connect a long vertical run of open pipe to a ball valve on a tee. Open the valve at system start up to allow air to escape, then close it as the pipe fills. Air/Vacuum valves are also used on tanks for the same purpose. If you look at enough piping systems, you’ll find a combination of valves and do-it-yourself remedies installed to rid the lines of air.
The solution – as you probably know by now – is an air release valve. The Plast-O-Matic Series ARV (shown in the diagram below) will automatically vent air during start-up of the system. Series ARV is normally open, and air is expelled as the system pressurizes. As the liquid rises, the self-guided poppet closes and ultimately seals bubble tight. When the system is shut down and liquid level drops, the valve re-opens.
A further safeguard is to use a degassing valve, Series DGV, which releases trace amounts of air as the system is operational. In many applications, both the air release and the degassing function are required. For these situations it is recommended to use both valves, or a single combination valve, such as Series CARD.
Below: An automatic Degassing Valve is one of the recommended tools to minimize entrained gas in a liquid piping system
