Why buy GESTRA check valves from Fergo?

Fergo is an authorised GESTRA partner and offers three decisive advantages over direct supply or other distributors: competitive industrial pricing visible in the shop without request for quotation, warehouse stock in Neuss (Germany) with dispatch in 1–2 working days via DHL across Europe, and a complete solution — combine GESTRA check valves with GESTRA steam traps, Fergo disc check valves and flanged lift check valves from one source, one contact, one delivery.

Applications — steam, condensate, power plants and chemicals

GESTRA check valves are the first choice in steam and condensate systems. In steam plants, metallic-seated RK86 and RK76 secure the line downstream of steam traps and heat exchangers. In power plants and district heating, CB26 flanged valves protect high-pressure lines from backflow. In the chemical industry, stainless steel RK86A with EPDM seat isolate reactive process lines. In water treatment, RK44 bronze valves prevent backflow in drinking water and cooling circuits. In building services, MB14 brass valves protect heating circulating pumps. Check material compatibility with the resistance check tool.

GESTRA check valve in stock — EU-wide delivery

Fergo stocks all 127 GESTRA check valve variants — original packaging with full GESTRA documentation. Dispatch in 1–2 working days across Europe. Each valve ships with datasheet and declaration of conformity. All certificates are in the shop. For project quantities or special configurations the Fergo team prepares an individual quotation.
