All animal rights activists may rest assured; we do not intend to fit valves from our factory to elephants in the future. Elephants do not need them anyway. Their trunk is a multifunctional organ: for feeling, gripping, breathing, smelling and fighting. The trunk is also used as a suction and pressure pump thus allowing the elephant to drink 200 litres of water in 5 minutes. The trunk can also be used to spread dirt and dust over the skin. No matter whether it's regulating or controlling, water or highly viscous media, the elephant and nieruf can cope it.
»That's why we believe that the elephant best represents the diversity of our valves.«
Through our comprehensive product range of industrial fittings, we can supply the right valve for every budget, no matter whether low-price needle valves or high-price and sophisticated pressure reducing valves. In the scope of master agreements and great purchase quantities, we are happy to grant you project-specific discounts. High-quality industrial fittings at low prices with fast delivery times. That’s what NieRuf stands for. Should you have product-specific questions during the planning stage of your pipeline project, please don’t hesitate to contact the NieRuf industrial valves team at any time. Our competent employees can find the right solution for your problem in the area of industrial valves and measurement technology. Building pipelines with industrial fittings is a part of every industry. In ship building, pipelines are built in for the fuel inflow with solenoid valves. In biogas plants, pipelines with ball valves are utilised for the gas supply. In cooling systems, pipelines with butterfly valves are used for the inflow of cooling agents. In building technology, pipelines with check valves are utilised in the area of water and waste water. In the oil industry, oil tanks are fitted with sight glass fittings. In heating engineering, overflow valves are utilised as so-called bypass valves in combination with angle seat valves. In all these areas of application, industrial fittings by NieRuf play an essential role. The industrial fittings are utilised to control and adjust media within pipelines and also serve the purpose of protecting the facility depending on the fitting, such as safety valves, vent-valves or strainers. Thanks to our comprehensive range of industrial fittings with thousands of articles, we have the right product for any area of application. Whenever a medium has to be adjusted or blocked, this should be controlled and monitored. NieRuf GmbH supplies a variety of different measurement technology fittings. You can, for example, purchase temperature devices in different designs and for all kinds of temperature ranges to control the temperature of liquid and gaseous media. With float valves you can monitor the filling levels of containers, even if you cannot measure them. The float valve regulates the inflow or outflow of a liquid into or out of the container fully-automatically. Via our electronic pressure sensors, you can measure and visualise the existing pressure in your pipeline system or container system. With our manometers, also available with a glycerine filling, you can have the pressure displayed in bar directly at the point of measurement. This is usually built directly into a fitting, for example before and after a pressure-reducing valve or through a siphon and a manometer gauge valve. Through our fluid level gauges and point level switches, you can always keep an eye on the filling levels in your containers or pipelines. Should the limit level be reached, this is automatically transmitted to your control system. Through our variable area meters you can also keep an eye on the flow. We are happy to help you select the right measurement technology component for you.
