Compact and Versatile Wafer-Type Check Valve – GESTRA RK 76 Series



GESTRA RK 76 Series
Pressure ratings: PN 6/10/16/25/40, ASME Class 125/150/300
Size range: DN 15–100, NPS ½″–4″
Description
The GESTRA RK 76 is a compact and highly reliable wafer-type check valve designed to prevent reverse flow in steam, gas, and liquid systems. Thanks to its spring-loaded disc mechanism, it supports installation in any orientation, including horizontal and vertical lines.
For models without a spring, installation is only permitted in vertical lines with upward flow.
The integrated spiral centering ring ensures precise alignment between flanges, facilitating fast and accurate assembly. This design is ideal for space-constrained systems and applications that demand consistent sealing performance.
✅ Application Areas
GESTRA RK 76 valves are used across a broad spectrum of industries where safe and efficient backflow prevention is essential:
Steam distribution systems in industrial and energy facilities
Condensate return lines in boiler and steam systems
HVAC systems for heating and cooling applications
Hot and cold water distribution networks
Compressed air and inert gas lines
Chemical and petrochemical plants
Pump discharge and bypass systems
District heating installations and energy centers
Oil & gas flow control systems
Industrial process lines handling clean or slightly contaminated fluids
