✔ Design requirements:
- Resistance to dezincification of copper alloys
- Compliance with specific stainless steel grades (e.g., for the ball)
- Connection requirements
- Ensure the correct closing direction is maintained
- Rotation stops must clearly indicate the positions (open or closed)
- Compliance with internal diameters to ensure full bore flow
✔ Performance requirements:
- Controlled operating torque
- Sealing
- Sealing angle (seat overlap angle on the ball)
✔ Durability tests:
- Torsion tests
- Bending tests
- Mechanical stop tests
- Acoustic tests (Class 1: ≤ 20 dB)
- Endurance tests (cycle requirements)
Our mechanical tests carried out on 
The DVGW certification for drinking water is currently in progress.
Principle of the drilled ball
Drilled ball shut-off valves, when in the open position, help prevent water retention zones between the ball and the valve body, which could otherwise promote bacterial growth and limescale build-up.
