KSB VALVE - KNIFE GATE VALVE HERA-BD

1. Straightforward installation of pneumatic and electric actuators and position switches

• This is ensured by a robust and compact steel mounting yoke. A hard anodised aluminium NAMUR adaptor plate attached to the actuator also allows proximity switches or solenoid valves to be quickly installed (plug & run).

2. Reliable and service-friendly stem seal

• The gland packing is made of PTFE impregnated fibre and can be re-adjusted during operation. When replacing the packing, there is no need to remove the valve from the piping.

3. High functional reliability and safe sealing in both flow directions 

• The stainless steel valve disc is polished on both sides and guided by a confined U-shaped seal along the entire valve travel. This prevents “chattering” of the disc and minimises the risk of deposits.
• Flushing corners in the body ensure the seat is flushed-clean when the valve closes.

4. Suitable for universal use

• Since the flange is connected via threaded pocket holes and throughbolts, the gate valve can be used as wafer-type or dead-end valve at full operating pressure.

5. Economical 

• The valve is available in a single-piece (up to DN 500) or two-piece body design with full bore providing unrestricted flow passage. The body is completely machined inside, leading to a tight fit of all components, very low pressure losses and high flow rates.
• As a standard feature, O-rings are integrated into the body and serve as flange seals. This helps to save extra costs for providing and fitting external flange seals.
