– All cast iron and steel components are protected against corrosion by high-quality epoxy coating.
– Robust and compact steel yoke for straightforward mounting of pneumatic and electric actuators and position switches. A hard anodised aluminium NAMUR adapter plate attached to the actuator allows sensors or solenoid valves to be quickly installed (plug & run).
– Reliable and service-friendly stem seal: The gland packing is made of PTFE impregnated fibre and can be re-adjusted during operation. There is no need to remove the valve from the piping to replace the packing.
– High functional reliability and tight shut-off in both flow directions

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

– Suitable for universal use. Flange connection via tapped blind holes and throughbolts enables the wafer-type knife gate valve to be clamped between pipe flanges or used as dead-end valve at full operating pressure.
– Economically efficient

– The valve is available in a single-piece or two-piece body design with full bore providing unrestricted flow passage. The body is fully machined inside, resulting in a tight fit of all components, very low pressure losses and high flow coefficients.
– 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.
