从China供应商批发进口4 8 12 Electric Actuated Butterfly Valves Parts — FOB条款

These 4 8 12 electric actuated butterfly valve parts use QT450-10 ductile iron for the valve body and disc, a material grade with a minimum tensile strength of 450 MPa and elongation exceeding 10 percent. The casting achieves a ball rate above grade 3, which reduces porosity and improves mechanical integrity under pressure. The solid-body design increases weight for the same caliber compared to hollow alternatives, adding structural rigidity in high-flow applications.

The seat is lined with standard EPDM rubber, delivering resilience and tension stability that allows the valve to exceed 10,000 open-close cycles without leakage. The valve body undergoes an electrostatic powder thermal spraying process with a 250 µm coating thickness, followed by curing at 180 °C for two hours and a 200 °C preheat for three hours. This treatment doubles surface adhesion versus conventional powder coating and extends colorfastness to 36 months in outdoor conditions.

These parts suit industrial pipelines in water treatment, HVAC, and chemical processing, where reliable sealing and actuator compatibility are critical. Buyers typically confirm actuator torque requirements and flange standards before ordering. Lead time, MOQ, and Incoterms are supplier-specific and must be verified directly with Luoyang Yifa Machinery Technology Co., Ltd.

Luoyang Yifa Machinery Technology Co., Ltd operates from No.905, Century International Building 17 at the intersection of Qingdao Road and Jiudu Road in Luoyang’s High-Tech District, Henan Province. The company’s address places it within a recognized industrial hub for machinery and valve manufacturing in central China.

The supplier holds a harbor trust tier on the platform, though its response rate and average response hours are currently unrecorded. No additional certifications, client lists, or production scale details are provided in the listing, so these must be requested directly from the company.
