Contact Julong RubberCategory Overview
Valve rubber parts are elastomer components used for sealing, flow control, pressure response, isolation, and protection in industrial valve systems. Julong Rubber manufactures custom molded valve diaphragms, seals, gaskets, sleeves, seats, boots, O-rings, and other rubber components according to customer drawings, samples, and application requirements.
Available materials include EPDM, NBR, HNBR, silicone, FKM, natural rubber, SBR, and other elastomers. Material selection depends on the operating media, temperature, pressure, movement, chemical exposure, sealing requirements, and expected service conditions.
Our custom valve rubber parts can be developed for water valves, air valves, control valves, pinch valves, diaphragm valves, check valves, pressure-regulating equipment, pumps, and other fluid-handling systems. Dimensions, hardness, tolerances, material grades, testing requirements, and production quantities are available upon request.
Manufacturing Process
See how custom rubber components move through material preparation, production, secondary processing, inspection, batch manufacturing and shipment. Real production photos provide a more direct view of the manufacturing process behind each order.
The exact production route varies by product, material, tooling and manufacturing process.
Material preparation starts according to the specified rubber type, hardness and project requirements before production begins.
Rubber material is prepared for the required manufacturing route, which may include cutting, weighing, preforming or extrusion preparation.
Parts are molded, extruded or otherwise formed according to the product design, tooling and selected rubber manufacturing process.
After primary forming, required secondary operations can include trimming, cutting, joining, bonding or other product-specific finishing processes.
Dimensions, appearance and specified characteristics can be checked during production according to the drawing and agreed inspection requirements.
Approved production conditions are carried into repeat manufacturing, with batch output prepared for inspection, handling and final release.
Finished parts are prepared for final inspection, packing, identification and shipment according to the confirmed order requirements.
