Flühs Valve Technology

Heating valves regulate heating-water flow and temperature in heating systems. Flühs supplies specialized turned parts that integrate into heating valves to enable precise temperature control.

Air vent valves are used to release trapped air or discharge excess water from pipelines, tanks, or other vessels. Flühs valves support efficient water circulation and help prevent unwanted pressure fluctuations in piping systems.

A shut‑off valve (also called a stop or isolation valve) regulates flow in gas or water lines in residential and industrial buildings. The wide Flühs portfolio in valve technology includes numerous valves with an integrated shut‑off function and offers a configurable shut‑off valve solution for isolating main and branch service lines.

A thermostatic valve in sanitary installations controls hot‑ and cold‑water flow to a pre‑set outlet temperature. A special wax element expands when the set temperature is exceeded (and contracts when it drops below), causing the valve to open or close and keeping the mixed‑water temperature constant. Across all sizes, Flühs thermostatic valves use premium components made from special brass. Combined with our patented differential drive, they deliver very fast response times and stable water temperature. In comparative testing against like‑for‑like competitors, our S18 Thermostar valve achieved the fastest response time.

Plumbing valves for sanitary applications regulate and control flow, examples include ball valves, shut‑off valves, diaphragm valves, bellows‑sealed valves, and plug valves. Flühs valve technology for controlling water flow in sanitary systems is a worldwide market leader and currently comprises roughly 1,400 active valve assemblies.

More about Plumbing Valves

Water valves are manual or electric valves used to regulate water flow and maintain pressure in water‑supply systems, for example, in potable‑water installations or irrigation systems. Flühs valves are used primarily in the plumbing industry for shower, lavatory, or kitchen fixtures.

A valve for 3‑hole fittings provides shut‑off and flow control for fittings with 2 separate controls and one spout (e.g., a cold‑water tap and a hot‑water tap). Flühs offers complete, high‑performance solutions with Unit and Drop‑in valves that are easy to install.

Mixing valves blend cold and hot water to a certain temperature and typically have two inlets and one outlet. Examples include the Flühs Mix valve and the Flühs Promix valve. In addition to precise flow and temperature control, Promix can optionally provide an energy‑saving cold‑start function.

Ball valves are a type of shut‑off valve in which a rotating ball regulates the flow of water or gas. They are used in heating and plumbing systems and across many industries. While the Flühs Shut‑Off valve is not constructed as a ball valve, it enables comparably fast, effective control and positive shut‑off of flow.

A diaphragm valve uses a flexible diaphragm to regulate or shut off gases or liquids in industrial processes. Flühs focuses on drinking‑water valves that achieve control and shut‑off via cones or ceramic discs rather than diaphragms.

A bellows‑sealed valve offers high hermetic sealing to prevent leakage, typically used in industrial piping with hazardous media. Flühs valves are designed for potable‑water systems and employ elastic sealing discs (for example in the Classic valve) and, where applicable, o‑ring or lip seals (for example in the Lifetime valve) to ensure durability and tightness.

An in‑wall valve is a shut‑off valve commonly installed behind the wall or panels in residential and commercial buildings, with only the operator visible. The in‑wall version of the Flühs Shut‑Off valves can be adjusted via the spindle to the required wall thickness for precise on‑site alignment.

A check valve (also called a non‑return or backflow‑preventer valve) allows flow in only one direction and is often used in heating or cooling systems. Examples include the Flühs Classic RS  and the KFR valve. A spring‑loaded sealing cone ensures the fitting is only traversed in the intended direction.

A free‑flow valve is a shut‑off fitting in potable‑water installations in which the valve disc moves completely out of the flow channel when opened, minimizing pressure loss. In Flühs Shut‑Off assemblies, for example, Classic or Lifetime headworks provide the shut‑off function, while a free‑flow path enables high‑capacity flow.

A KFR valve combines a free‑flow valve with an integrated check valve and is used in potable‑water installations, e.g., at the building’s water service entry. It prevents water from the private network from flowing back into the public water‑supply grid. The Flühs KFR valve uses sealing cones to stop backflow.

A diverter redirects water within a fitting to one of several outlets, for example, from the tub spout to a hand shower. The Flühs Motion valve uses ceramic discs to switch water across up to 3 ways and allows targeted flow control as well as shut‑off of the entire unit.

A plug valve is a type of shut‑off valve that uses a conical obturator instead of a ball. In Flühs valves, shut‑off is achieved via ceramic discs, a cone‑and‑seat combination, or custom solutions.
