STAR valve flange: Perfect valve connection
With dimensions specially designed for valves, STAR valve flanges for connections to valves offer the perfect connection of PE to steel and cast iron without any misalignment.
This is why the STAR valve flange is ideal for valve connections:
Reduced dead space for ideal flow behavior
Offset-free, nominal width connection
Force-fit connection without tilting effect
For offset-free connections
Conventional PE dimensions do not match the standard dimensions of steel and cast iron pipes. The dimensions of the STAR valve flange, on the other hand, have been precisely matched to such connections. This makes it possible to create a connection from PE to steel and cast iron that merges without offset.
- Reduced dead space for ideal flow behavior
- Offset-free, nominal width-compliant connection
- Force-fit connection without tilting effect
Cost optimization by using a special flange
Choosing the right connection variant has a direct influence on the cost- efficiency of a pipe connection. Variant A shows the classic solution with a stub end and loose flange on a DN 400 fitting. Variant B, on the other hand, uses a special flange that enables the connection of a DN 350 fitting - with the same pipe diameter of d 400 mm.
The advantage: the smaller fitting enables significant cost savings to be achieved without reducing the flow capacity of the PE pipe. The special flange ensures a connection with the correct nominal diameter and enables more economical planning.

Choosing the right flange connection
Choosing the right flange connection is essential for the operational safety and durability of a pipeline. Different flange types are used depending on the pressure, temperature or material requirements of the continuing pipeline. The following diagram shows when which flange type is the best choice.
