How to perform routine maintenance and seal replacement for plastic valves?
1. Regular inspection of valve body and sealing surfaces: Visually inspect the valve body, seat, and gaskets monthly, recording any scratches, wear, or signs of aging.
2. Cleaning and lubrication: Use a lint-free cloth or specialized cleaner to remove oil and dust from the valve body surface; apply a suitable amount of chemically resistant lubricant to moving parts (such as springs and valve stems) to prevent jamming.
3. Quick steps for seal replacement: ① Remove the valve body and secure the mounting block; ② Quickly release the old gasket using the snap-fit structure between the spring and the mounting plate; ③ After checking the spring and mounting rod for damage, install the new gasket and re-snap it. This patented snap-fit limiting design significantly improves replacement efficiency and is applicable to the entire range of plastic valves from Jiangsu Leiting Precision New Materials Co., Ltd.
4. Functional verification: After replacement, perform a closed/open cycle test to confirm no leakage and smooth operation before putting the valve into use.
What are the key considerations for packaging and shipping PlasticValveSeries products?
1. Packaging Material Selection: Use moisture-proof and shock-proof polyethylene or corrugated cardboard boxes, clearly marked with "Moisture-proof, Pressure-proof" to ensure the valve body is protected from moisture or impact damage during long-distance transport.
2. Protective Measures: Each valve body is internally filled with PE foam or EPE granules, and partitions are installed between valve bodies to prevent mutual friction; soft protective sleeves are added to easily scratched valve covers and flanges.
3. Labeling and Instructions: The packaging must clearly indicate the product model, specifications, weight, quantity per carton, and the words "Lightweight Plastic Valve"; a user manual should also be included for quick identification by the customer on-site.
4. Transportation Method and Loading: Flatbed trucks or containers are preferred for full container transport. Keep the container level during loading to avoid tilting or severe bumps; for large shipments, pallet stacking can be used, with sufficient gaps between pallets to prevent deformation under pressure.
Advantages of PlasticValveSeries in Practical Applications:
1. Lightweight and High-Strength: Compared to metal valves, plastic valves weigh only 30%~40% of metal valves, reducing pipeline support structure costs.
2. Corrosion-Resistant and Scaling-Free: Utilizing high-molecular materials (such as PTFE and modified polyurethane), they maintain long-term sealing performance in strong acid, alkali, and salt spray environments, making them suitable for demanding industries such as solar energy, semiconductors, and chemicals.
3. Integrated Connection: The valve body can be directly heat-fused or snap-fitted to plastic pipes, eliminating the need for additional flange gaskets, shortening installation time and reducing leakage risk.
4. Technological Innovation and Patent Protection: As of December 2024, the company held 81 patents (36 invention patents, 36 utility model patents, and 9 design patents), including a snap-fit structure for easy seal replacement, further enhancing maintenance convenience.
