Pressure regulating valves are indispensable components for the safe and efficient control of pressure in industrial systems. They protect systems from overload, ensure constant operating conditions and extend the service life of your equipment. Our product range includes pressure reducing valves and overflow valves for water, steam, neutral liquids and gases – all manufactured in accordance with international standards such as DIN EN and PED.
Pressure reducing valves and pressure reducing valves reliably reduce the inlet pressure to a constant, lower outlet pressure. They are indispensable for protecting pipelines, valves and devices as well as for optimizing processes in industrial applications. Our pressure reducing valves are diaphragm-controlled and spring-loaded, which ensures precise control and maximum operational reliability. Whether for water, steam or gases – the pressure reducing valves in our range offer a long service life, easy maintenance and comply with international standards such as DIN EN and PED.

Overflow valves and overflow regulators are essential safety elements in hydraulic and pneumatic systems. They reliably protect systems against overpressure by automatically discharging excess pressure and thus preventing damage to pumps, pipes and valves. While overflow valves are primarily used in circuits with variable loads, overflow regulators also have the additional task of precisely controlling the pressure and keeping it constant. Both components ensure stable operation, extend the service life of the system and increase energy efficiency. Our overflow valves and overflow regulators are suitable for liquids, gases and steam and comply with international standards such as DIN EN and PED.

and special solutions possible
Our pressure regulating valves are not only used in classic pipelines, but are also an integral part of modern SKID systems, pressure reducing stations and control stations. They ensure precise pressure control in compact, pre-assembled systems and guarantee maximum operational safety and efficiency. Whether for water, steam or gases – we plan, configure and install complete valve solutions including pressure reducing valves and overflow valves.
Thanks to our experience in pipeline construction and stainless steel pipe assemblies, we integrate pressure regulating valves seamlessly into your systems – from design and production to turnkey installation.
Pressure regulating valves are used to control and stabilize the pressure in piping systems. They protect systems from overloading, ensure constant operating conditions and increase safety and efficiency.
There are two main types:
Pressure reducing valves (pressure reducing valves): Reduce the inlet pressure to a constant, lower outlet pressure.
Overflow valves and overflow regulators: Divert excess pressure or actively regulate it to prevent overpressure.
Our valves are suitable for water, neutral liquids, gases and steam. The choice of material and gaskets depends on the medium and temperature range.
All products comply with the relevant standards such as DIN EN, PED (Pressure Equipment Directive) and optionally TA-Luft for low-emission versions.
Yes, we offer variants for high temperatures (up to 400 °C), low temperature ranges, ATEX zones and special connections (ANSI, JIS, butt weld ends) on request.
Adjustment is made via a spring cover or an adjusting screw. Pneumatic control is also possible on certain models.
Many models are designed to be low-maintenance or maintenance-free. Others offer easy maintenance thanks to replaceable cartridges or membranes.
