High-pressure valves
Why URACA valves?
URACA has been known for decades for the highest quality in the construction of high-pressure positive displacement pumps and high-pressure valves. In order to consistently meet this requirement, URACA in Bad Urach develops and manufactures highly reliable and durable valves for small to very large flow rates and system pressures of over 3,000 bar.
On the one hand, we can serve a multitude of necessary and meaningful individual functions, on the other hand the uniquely broad spectrum of valve types also covers many combinations of functions. This allows systems and plants to be built in a much more compact, efficient and cost-effective manner. As a further special feature, URACA valves offer maximum personal safety for the operator. Switching positions can be reliably and precisely queried and evaluated in the system control. Depending on the valve type, it can be used in potentially explosive areas up to zone 2. Highest material quality allows the use with different media and medium temperatures.
Almost all URACA switching valves can shut off a consumer line reliably against full operating pressure without auxiliary energy.
Cascadable URACA valves can be assembled extremely compactly to form a valve station.

URACA has developed hermetic process diaphragm pumps for these applications, which are available as individual special designs.
Advantages of the URACA process diaphragm pumps- emission-free handling of critical media
- space-saving thanks to T-arrangement of the diaphragm heads
- proven drive technology
- simple modernization of existing systems
