Electric Actuated Butterfly Valve DN50-DN900 - China Suppliers & Factory for High Quality Valves

Delivers a tight shut‑off with no leakage at the maximum rated pressure.

The only valve parts exposed to the medium are the seat and the disc.

Optimized for handling abrasive or erosive fluids.

Equipped with a cartridge‑type seat that can be replaced on‑site. The seat consists of a reinforced backing ring onto which the elastomer is vulcanized. Once the valve is bolted between pipe flanges, the seat remains stable, resisting any deformation or movement. The cartridge design also prevents issues like elastomer stretching or bending ahead of the disc during operation.

Provides a wide variety of material choices.

Includes a standardized actuator mounting flange to allow quick interchange of operators.

A top bushing takes up side thrust loads.

Hub sealing relies on preloaded contact between the flattened seat surface and the disc hub, ensuring a positive seal across all disc positions.

The one‑piece, wafer‑thin disc and stem design results in extremely low flow restriction.

The seat is replaceable without removing the valve from the pipeline, effectively isolating the body and stem from the fluid.

Molded‑in O‑rings serve as flange seals, removing the need for separate gaskets.

Universal mounting flange: The integrally cast actuator flange meets ISO 5211 dimensions, making it compatible with a wide range of operators—including 10‑position handle kits, gear operators, electric actuators, and pneumatic actuators.
