The flanged ball valve stainless steel (KH155 / KH155-F1) is the first choice for corrosive media, chemical and pharmaceutical service. The ball is manufactured from 1.4408, chrome-plated for wear resistance, with a standard TFM1600 (PTFE) seal rated for −29 °C to +175 °C. For DVGW gas installations the KH121 series in ductile iron provides the required certification. For chemically aggressive media, PFA-lined ball valves with GGG40.3 body are available.

Pneumatic and electric flanged ball valve
FERGO assembles pneumatic and electric flanged ball valves in-house — including actuator sizing, NAMUR solenoid valve, limit switch box, inductive sensor, mounting bracket and pressure testing to EN 12266-1. The fully assembled packages ship ready for installation.
A pneumatic flanged ball valve uses a quarter-turn pneumatic actuator — double-acting for process control or single-acting (spring return NC/NO) for fail-safe shut-off. An electric flanged ball valve uses the J4C multi-voltage rotary actuator (24–240V AC/DC) for remote control, timer-based switching or integration with PLC and building automation systems.
Compact flanged ball valve KH156 — up to 60% shorter
The compact flanged ball valve KH156 is an ultra-short full bore flanged ball valve in stainless steel 1.4408. With a face-to-face length of just 42 mm at DN15, 68 mm at DN50 and 88 mm at DN80, the KH156 saves up to 60% installation length compared to standard EN 558-1 Series 14. Despite its short body, the compact flanged ball valve carries TA Luft, Fire Safe, ATEX and AD2000-A4 certifications. It suits retrofit situations and tight installations where a standard-length flange-end ball valve would not fit. The KH156 is available with hand lever, pneumatic and electric actuation.

Media compatibility can be verified using the resistance check tool. For requirements beyond the standard range, FERGO engineers configure custom solutions.

Flanged ball valves in stock — EU-wide delivery
FERGO stocks 684 flanged ball valve variants for immediate dispatch across Europe. Manual and automated, DN15 to DN200, PN10 to PN100. Standard shipping via DHL typically arrives in 2–7 working days. Each flanged ball valve ships with datasheet and declaration of conformity. All certificates — TA Luft, Fire Safe, DVGW, SIL 3, AD2000, ATEX — are available in detail.
A 3-way ball valve is used to divert, distribute, or mix flow within a pipeline system — all with a single quarter-turn. Typical applications include process and chemical plants, HVAC systems, water supply networks, and industrial automation. Fergo stocks over 250 models ready to ship — browse the full range.
Fergo supplies 3-way ball valves in the following materials:
Nickel-plated brass – for water, air, and neutral media up to 25 bar
Stainless steel 1.4408 – for aggressive media, high temperatures up to +180 °C, and up to 63 bar
Ductile iron + PFA lining – for highly corrosive chemical media
All materials are available from stock. Technical data sheets available on request.
An L-port 3-way ball valve always connects two of the three ports while the third remains closed. It is ideal for diverting flow between two outlets (A→B or A→C) with a 90° turn. A T-port 3-way ball valve can connect all three ports simultaneously, enabling both mixing (two inlets → one outlet) and splitting (one inlet → two outlets). The correct choice depends on the switching function required in your system. Our technical team is happy to advise — contact us.
Yes. Many manual 3-way ball valves can be retrofitted with a pneumatic or electric actuator at a later stage. The requirement is an ISO 5211-compatible mounting flange on the valve. On request, our team handles actuator sizing, assembly, and delivery of the complete mounted set. Request a quote.
All in-stock models are dispatched the same day for orders placed before 15:00 — via DHL parcel or freight carrier for larger quantities. Deliveries are made across Europe. Current stock availability and lead times are shown directly on each product page.
