DN 20 TO DN 50 – SINGLE SHAFT DESIGN
- Lower friction and pressure losses for optimised Kvs values.
- Optimised disc design means less turbulence and a shorter outlet section – just 2 x DN – downstream of the valve.
- Less turbulence also has the advantage of less noise and vibration in the system.
- Less dirt deposits.
OPTIMISED FLOW
Due to the optimised disc design, leading to a shorter outlet section.
OPTIMISED SAFETY
Due to the polygon connection, stiffer disc and blow-out protection.
OPTIMISED EFFICIENCY
Due to the optimised Kvs values and ease of servicing, enabling more compact systems. Can be fully insulated.
