Two-Way Ball Valve ZEROVAL-K2H
The classic build of our two-way ball valve, with DIN flanged ends PN 25 — fully cavity-free and piggable. TA-Luft certified for chemical and emission-controlled plants; the seat concept is protected as a German utility model.
Tested for tightness.
The ZEROVAL-K2H two-way ball valve meets the German TA-Luft regulation — the principal regulatory requirement for limiting fugitive emissions in chemical and solvent plants. Stem and body seals stay below the required leakage rate over time, tested and certified.
In-house design.
The cavity-free seat concept is an in-house development of ES Armaturen and is registered as a utility model at the German Patent and Trademark Office — not a copy, but a structurally independent design proven for years in food, pharma and chemical plants.
The standard model in the ZEROVAL family.
If you need a classic two-way ball valve with DIN flanged ends, the ZEROVAL-K2H is the model. Robust, well-stocked, established in many applications — and fully cavity-free thanks to our patented seat concept.
- TA-Luft certified — verified tightness for chemical and emission-controlled plants.
- Utility-model protected — patented cavity-free seat concept, in-house development.
- Fully cavity-free — no gaps between ball, seat and body.
- Piggable — full unrestricted bore, compatible with pigging systems.
- Wide size range — DN 15 to DN 150, all at PN 25.
- CIP/SIP-capable — cleanable and steam-sterilisable in place.
- FDA-compliant seals — PTFE seat suitable for direct product contact.
- Manual or pneumatic — lever, rack-and-pinion actuator, position feedback.

Four industries, one standard.
Food & beverage
Dairy, beer, juices, syrups — wherever hygiene and cleanability govern product quality. Fully cavity-free, FDA-compliant seals, CIP/SIP-capable.
Pharmaceutical
Sterile processes, API solutions, intermediates. Complementary to the aseptic compact valve ZEROVAL-KC, the K2H is the standard for flanged applications.
Cosmetics
Creams, pastes, emulsions, shower gels. The cavity-free build prevents product residues and enables fast product changeovers.
Chemical
Coatings, adhesives, solvents, reaction mixes. TA-Luft certified — the legal basis for use in German chemical plants.
Which build fits your plant?
All three are two-way ball valves — they differ in connection and face-to-face. The K2H is the classic standard build with DIN flanged ends.
Standard build · Flanged PN 25
Classic DIN flanged connection. TA-Luft certified. For food, pharma, cosmetics and chemicals. DN 15 – DN 150.
Wafer build · Sandwiched
Most compact face-to-face — sandwiched between DIN PN 16 mating flanges. Ideal where install space is tight.
Compact build · DIN 11864/2
Aseptic flange contour machined into the body. Drop-in for aseptic pharma and biotech piping.
Two-way ball valve questions.
What is a two-way ball valve?
A two-way ball valve is a 2-port valve that opens or shuts the flow in a straight pipe run. With the valve open, the ball bore matches the pipe ID — full bore with no restriction. The ZEROVAL-K2H adds a fully cavity-free seat, making it suitable for hygienic applications.
What does TA-Luft certification mean for a ball valve?
TA-Luft (Technische Anleitung zur Reinhaltung der Luft) is the German regulation limiting fugitive emissions from industrial plants. A TA-Luft certificate proves that the valve's stem and body seals stay below the required leakage rate over time — mandatory in chemical, coatings and solvent plants in Germany.
What is utility-model protection?
The cavity-free seat concept of the ZEROVAL-K2H is registered as a utility model (Gebrauchsmuster) at the German Patent and Trademark Office. It is an in-house development of ES Armaturen — not a copy and not a licence, but a structurally independent design.
What sizes and pressure ratings are available?
The ZEROVAL-K2H two-way ball valve is supplied as standard from DN 15 to DN 150 at PN 25. Higher pressure classes are available on request.
How does the K2H differ from the wafer and compact ball valves?
All three are two-way ball valves. The K2H is the classic standard build with DIN flanged ends PN 25 — robust, TA-Luft certified. The Wafer ball valve ZEROVAL-WF is a more compact wafer build for DIN PN 16 mating flanges. The Compact ball valve ZEROVAL-KC carries the DIN 11864/2 aseptic flange contour directly on the body, for aseptic pharma and biotech piping.
