Technical documentation
Benefits
- · Design and Sealing
- The floating ball is automatically pressed against the downstream seat by the pressure of the medium, ensuring reliable tightness
- Pressure increase = increase in sealing force, making the valve highly reliable under pressure fluctuations
- 2- or 3-piece body simplifies maintenance and repair
- · Safety and Reliability
- Anti-blow out stem for protection against accidental stem ejection
- Anti-static device prevents spark generation in flammable media
- 100% sealing and functionality tests in accordance with international standards
- · Wide Temperature Range
- Special designs:
— Down to -196 °C (cryogenic conditions)
— Up to +800 °C (high-temperature environments) - · Customer Adaptability
- Compatible with all standard connections: DIN / ASME / JIS / weld ends
- Customizable material selection including metals, carbon seals, PTFE, PEEK
- Steam jackets, piggable designs, special testing (PMI, helium tightness, fire safety, etc.)
