Gietijzeren handmatige mesgatklep - DN200

Key Features

· Material: High-strength cast iron body with stainless steel (SS304/SS316) blade for superior wear and corrosion resistance.

· Size: DN200 (8") – compliant with ISO 6708 and ASME B16.10 standards.

· Pressure Rating: PN10/PN16, optimized for low-to-medium pressure systems.

· Sealing System: Resilient EPDM/NBR seals or optional metal-reinforced seals for tight shut-off in harsh conditions.

· Operation: Manual handwheel or lever actuator for easy, low-torque operation; non-rising stem design saves vertical space.

· Connection Type: Flanged ends (EN 1092-2, ASME B16.5, or customized to requirements).

· Blade Design: Ultra-thin, sharp-edged blade cuts through thick slurries and prevents particle buildup.

· Standards: ISO 16135, EN 12570, and tested per API 598 for leakage integrity.
