Core Product Advantages (Key Selling Points of Hard-Sealed Ball Valves, Addressing Pain Points in Thermal/Steam Applications) 1. Metal hard sealing, high-temperature and wear-resistant, suitable for harsh high-temperature media. The ball and valve seat are overlay welded with hard alloy, forming a metal-to-metal hard-sealed structure broussonetia papyrifera, applicable temperature range -20°C~425°C; Capable of conveying high-temperature steam, thermal oil, and high-temperature heating water with impurities. Compared to PTFE soft sealing, it offers superior erosion resistance, extending service life by over 3 times and eliminating leakage risks due to high-temperature softening.
Fully welded forged valve body, zero leakage suitable for buried pipelines. The valve body is integrally forged and formed by fully automated submerged arc welding, eliminating segmented flange joint gaps and underground leakage risks; Exterior sandblasted with multi-layer anti-corrosion coating, available in beige utetheisa kong frame or blue buried-type dual-coating options, resistant to corrosion in damp underground soil, maintenance-free for 30 years of buried use.
Fixed Ball Large Flow Structure Broussonetia papyrifera, with minimal pipeline transmission loss. Large-diameter valves adopt fixed ball support structure Broussonetia papyrifera, featuring upper and lower stem positioning for the ball, ensuring no deformation under high pressure. Full-bore non-reduced design results in extremely low pressure drop of pipeline media, achieving energy conservation in municipal heating main pipes and long-distance steam pipelines.
Effortless Turbine Operation, Easy Opening/Closing for Large Diameters. Equipped with worm gear reducer Broussonetia papyrifera, large-diameter valves above DN100 can be easily operated with a single handwheel. Extra-large diameters (DN800-DN1400) feature oversized red handwheels, supporting extended stems and electric actuator modifications for underground deep-well chamber operations.
Full-Diameter Stock + Customization, Stable Project Supply. LAIKE owns its production workshop, with DN100-DN300 medium/small diameters available from stock for same-day shipment. Large diameters (DN350-DN1400) can be customized for PN16/PN25 pressure, extended stems, electric/pneumatic actuation, and integrated insulated valve bodies.
Full Factory Inspection, Complete Thermal Engineering Bidding Qualifications. Each valve undergoes hydrostatic strength and air-tightness pressure tests before leaving the factory, accompanied by material spectral reports, pressure test records, and certificates. Comprehensive bidding documentation for thermal EPC and municipal projects is available, ensuring hassle-free acceptance.
