Technical documentation
Benefits
- Low Operating Torque
- High Pressure and Large Sizes
- Sealing and Safety
- Robust Design
- Global Standard Compliance
- Customizability
The fixed ball supported by a trunnion and driven through a stem eliminates the "floating" motion, lowering the required torque.
This facilitates automation with electric or pneumatic actuators, especially for large diameters.
Perfectly suited for high-pressure applications and medium to very large DN sizes where trunnion support ensures greater reliability than floating designs.
Spring-loaded sealing rings ensure tight shut-off, especially under high pressure.
Standard sealing on the inlet side; DBB/DIB options available for full isolation and drainage.
Blow-out proof stem and anti-static protection for safety in critical operations.
100% leak and function tested in accordance with international standards.
Compliant with ASME B16.34, API 608, PED / DGRL, TA-Luft (VDI 2440), and DIN ISO 15848-1 for emission and environmental safety.
Wide selection of body and sealing materials — from carbon steel to specialty alloys.
Optional configurations include:
Operating temperatures from -196 °C to +800 °C
Heating jackets, piggable design, DIB 1 / DIB 2
Reduced bore, custom painting, specialized testing (PMI, cryogenic, helium, fire-safe)
