PPR截止閥與閘閥產品說明
PPR截止閥和閘閥是流體控制系統中不可或缺的關鍵組件，采用優質無規共聚聚丙烯（PPR）材料制成，適用于冷熱水輸送、暖通系統及工業管道領域。產品涵蓋20mm、25mm、32mm、40mm、50mm、63mm等常用規格，可滿足不同場景的安裝需求。
材質特性
PPR材質具備優異的耐高溫性（長期耐受70℃水溫，短期耐受95℃水溫）、抗化學腐蝕性及環保安全性，長期使用不結垢、不滋生細菌，符合生活用水衛生要求。閥門內壁光滑，可有效降低流體阻力，減少能源損耗。
結構設計
截止閥采用精密模壓工藝成型，閥桿與閥座接觸面經過特殊處理，確保啟閉靈活且密封性能穩定；閘閥主體結構采用流線型設計，全通徑結構使流體通過時無阻礙，適用于需要完全開啟或關閉的管道場景。兩種閥門均配備耐磨損EPDM密封圈，有效防止滲漏，延長使用壽命。
應用優勢

規格參數
- 公稱直徑：20/25/32/40/50/63mm
- 工作壓力：PN20（常規冷水）/PN16（高溫熱水）
- 適用介質：冷熱水、中性液體
PPR Stop Valves & Gate Valves Product Description
PPR stop valves and gate valves are essential components in fluid control systems, manufactured from premium polypropylene random copolymer (PPR) material. These valves are widely used in cold/hot water supply, HVAC systems, and industrial pipelines, available in 20mm, 25mm, 32mm, 40mm, 50mm, and 63mm specifications to meet diverse installation requirements.
Material Properties
PPR material exhibits outstanding heat resistance (withstands 70℃ long-term and 95℃ short-term), chemical corrosion resistance, and environmental safety. The smooth inner surface prevents scaling and bacterial growth, ensuring compliance with potable water hygiene standards while minimizing flow resistance.
Structural Design
Stop valves feature precision-molded bodies with specially treated spindle-seat contact surfaces for smooth operation and reliable sealing. Gate valves adopt full-bore streamlined design for unrestricted flow in fully open/closed positions. Both types integrate wear-resistant EPDM sealing rings to prevent leakage and extend service life.
Functional Advantages
- Easy Installation: Compatible thermal fusion connection ensures seamless integration with PPR piping
- Low Maintenance: Excellent weather resistance and material stability reduce long-term upkeep
- Versatile Application: Multiple sizes accommodate varying flow demands in residential, agricultural, and commercial systems
Technical Parameters
- Nominal Diameter: 20/25/32/40/50/63mm
- Pressure Rating: PN20 (cold water)/PN16 (hot water)
- Compatible Media: Cold/hot water, neutral liquids
