1. Key Advantages
Zero Leakage Seal
- Hard alloy sealing surfaces (e.g. Stellite cobalt-based overlay welding), wear-resistant, high temperature resistant, in accordance with ISO 5208 standards, bearing pressure up to 16MPa.
Fast opening and closing
- Stem lifting design, short opening and closing stroke, labor-saving operation (handwheel or electric drive optional).
Long life
- 316L stainless steel stem + PTFE packing, resistant to high-frequency operation (more than 5 million times), maintenance-free design.
Multi-scenario adaptation
- Horizontal/vertical pipeline installation, suitable for chemical, food, pharmaceutical, energy and other industries.
