Control valves are indispensable components for precise control of liquids and gases in chemical process engineering, analytical technology and biotechnology. These shut-off valves enable reliable regulation or complete shut-off of media flow by screwing the spindle into the valve housing.

Material diversity for different requirements

The available materials offer optimal solutions for various application areas:

Polypropylene (PP) shows excellent resistance to lubricants, aliphatic hydrocarbons, alcohols, ketones as well as organic and inorganic acids at working temperatures from -5°C to +90°C.

Polyvinylidene fluoride (PVDF) as a fluoroplastic offers extended chemical resistance, particularly to halogenated solvents, ammonia solutions and UV radiation at temperatures from -30°C to +150°C.

Perfluoroalkoxy (PFA) is characterized by exceptional resistance to aromatic hydrocarbons, phenols and strong acids and operates reliably from -200°C to +260°C.

Polytetrafluoroethylene (PTFE) is considered the most chemically resistant fluoroplastic with virtually universal media compatibility and a temperature range from -60°C to +260°C.

Technical specifications

Fine control valves are offered with nominal diameters of 3 mm, 4 mm and 8 mm and achieve maximum flow rates of 60 to 600 l/h depending on the design. The maximum operating pressure is 6 bar at +20°C. All plastic valves undergo strict leak testing according to DIN 3230 and guarantee the highest quality standards.

Angle valves for sampling are equipped with internal thread G 1/4" and enable continuous, safe sample extraction from tubing systems. Needle valves made from PTFE guarantee highly accurate dosing for gases and liquids with tubing of 3/8" outer diameter.

Control valves and other products, such as diaphragm valves, solenoid valves and check valves, are available directly in the online shop of RCT Reichelt Chemietechnik. The range of RCT Reichelt Chemietechnik offers over 80,000 different products, which are used among others in mechanical engineering, chemical technology, process engineering as well as medical technology.
