Metal Valves
Robust and precise valve technology for industrial processes.
The reliable choice for the highest demands
Metal valves are essential across numerous industries. Whether in plant construction, process engineering, or filling systems – they stand out for their robustness, long service life, and reliability, even under the most demanding operating conditions.
-
The solenoid actuator opens or closes the valve directly, without the need for auxiliary pressure.
Ideal for vacuum applications, small nominal diameters, and systems that must operate from 0 bar.
-
The solenoid actuator controls only a small pilot orifice. The medium’s own pressure performs the main function and opens the valve. Ideal for large nominal diameters with low energy consumption. Requires a minimum pressure differential.
-
This principle combines both advantages. The valve is permanently linked to the solenoid actuator and is supported by medium pressure when required. Ideal for applications with fluctuating pressure conditions, as it remains fully functional from 0 bar.
Available control types
Types:​
-
Metal valves are available in multiple designs to suit different application needs:
-
2/2-way valves: Two ports, two positions – for straightforward flow control.
-
3/2-way valves: Three ports, two positions – commonly used for controlling double-acting cylinders.
-
5/2-way valves: Five ports, two positions – enable precise control in more complex systems.
Functions:
Normally closed (NC): In this setting, the valve remains closed when at rest and opens when power is applied.
Normally open (NO): Here the valve remains open in the resting state and closes as soon as power is applied.
Overview of housing materials​
-
Brass: Popular for its excellent corrosion resistance and strength, brass is a commonly used material in many applications.
-
Stainless steel 1.4305 (V2A steel): This stainless steel impresses with good corrosion resistance and easy cleaning, which makes it versatile.
-
Stainless steel 1.4571 (V4A steel): With even higher corrosion resistance than V2A steel, this material is particularly suitable for demanding operating conditions.
-
Aluminum: Lightweight yet strong, aluminum is ideal for applications where low weight is crucial.
-
Gunmetal: This copper-tin alloy is known for its high wear resistance and is used in demanding environments.
-
Grey cast iron GG25: A material with excellent thermal conductivity and wear resistance, often used in industry.
-
Cast steel GS-C25N: A high-strength steel that is ideal for demanding applications due to its good weldability and toughness.
