HERA-BD

Product catalog summary

Overview: The HERA®-BD Knife Gate Valve is designed for bi-directional sealing applications, suitable for water, wastewater, and solids-laden fluids across various industries including industrial plants, wastewater treatment, food and beverage, and biogas plants.

Key Features:

Corrosion Resistance: All nodular iron and steel components are protected by a high-quality epoxy coating.
Actuator Installation: The valve supports straightforward installation of pneumatic and electric actuators and position switches, facilitated by a robust steel mounting yoke and a hard anodised aluminium NAMUR adaptor plate.
Stem Seal Reliability: The gland packing is made of PTFE impregnated fibre, adjustable during operation, and replaceable without removing the valve from the piping.
Functional Reliability: The stainless steel valve disc is polished and guided by a U-shaped seal, preventing chattering and minimizing deposits. Flushing corners ensure the seat is clean when the valve closes.
Universal Use: The valve can be used as a wafer-type or dead-end valve at full operating pressure due to its flange connection design.
Economical Design: Available in single or two-piece body designs with full bore for unrestricted flow, integrated O-rings serve as flange seals, reducing additional costs.
