The stainless steel ball check valve (RB106) is the first choice for corrosive, hygienic or aggressive media — all wetted parts are 1.4408. The GGG40 ball backflow preventer (RB105) is the economical alternative for water and wastewater service with its self-cleaning aluminium ball.
Ball check valve flanged & threaded — connection types
| Connection | Nominal sizes | Bodies available | Standards |
|---|---|---|---|
| Flange PN16 | DN50–DN500 (GGG40) / DN15–DN300 (SS) | Stainless steel + GGG40 | EN 1092-2, EN 558-1 Series 48 |

Seal material — ball backflow preventer
| Seal | Temperature | Typical media |
|---|---|---|
| NBR (standard) | −20 °C to +80 °C | Water, wastewater, oils, greases, compressed air |
| PTFE | −20 °C to +150 °C | Acids, alkalis, solvents, aggressive chemicals |
| FKM / Viton | −15 °C to +200 °C | Hydrocarbons, fuels, higher temperatures |
Media compatibility can be verified using the resistance check tool.
Applications — ball check valves
| Industry | Recommended series | Seal |

| Irrigation / Cooling water | RB105 (GGG40) | NBR |
An upstream strainer protects the sealing face from coarse solids. In systems with high flow velocities, rubber expansion joints reduce water hammer at pump stop. For requirements beyond the standard range, FERGO engineers configure custom solutions — including PFA-lined versions.
Installation — ball backflow preventer
FERGO ball check valves can be installed horizontally and vertically (flow from bottom to top). The flow arrow on the body shows the correct direction. For flanged ball check valves, tighten bolts gradually in a cross pattern. Threaded ball check valves (BSP female) are screwed into the pipe socket with thread sealant tape or hemp.
Ball check valves in stock — EU-wide delivery
FERGO stocks over 60 ball check valves and ball backflow preventers — DN15 to DN500, in stainless steel 1.4408 and GGG40, flanged and threaded. Standard shipping via DHL arrives in 2–7 working days across Europe. Each ball check valve ships with datasheet and declaration of conformity. Certificates to EN 10204 (2.1 / 3.1) are available on request.
