34SL20HT/手動閥34S※-L20H-T中英文產品介紹
（中文部分）
34SL20HT系列手動控制閥是一款專為工業(yè)流體系統(tǒng)設計的精密操作裝置，采用模塊化結構理念開發(fā)，適用于水、氣、油等介質的流量控制與管路切換。閥體采用高精度加工工藝與耐腐蝕合金材料復合制造，內部結構經過流體動力學優(yōu)化，有效降低壓損并提升介質流通效率。
該產品以人性化操作為核心設計理念，配備符合人體工學的防滑旋轉手柄，操作扭矩低于行業(yè)常規(guī)產品15%，可實現(xiàn)單手輕松調節(jié)。閥芯組件采用多層復合密封技術，配合自潤滑軸承結構，確保在-20℃至150℃溫度范圍內長期保持穩(wěn)定密封性能。表面硬化處理工藝使關鍵運動部件耐磨性提升40%，大幅延長維護周期。產品支持水平或垂直方向安裝，適配DN15至DN50多種管徑規(guī)格，滿足冶金設備、食品加工線、船舶動力系統(tǒng)等場景的多樣化需求。
針對復雜工況環(huán)境，34SL20HT系列特別強化了環(huán)境適應性設計。殼體表面經特殊涂層處理，可抵御鹽霧、濕熱等嚴苛環(huán)境侵蝕。內置安全鎖定裝置可防止誤操作導致的系統(tǒng)異常，雙冗余密封結構確保在突發(fā)壓力波動時的系統(tǒng)安全性。產品采用快裝式模塊設計，維護時無需拆卸管路主體，顯著提升設備維護效率。經過百萬次動作測試驗證，其機械壽命達到國際同類產品先進水平。
（English Part）
The 34SL20HT series manual control valve is a precision-engineered fluid management solution designed for industrial pipeline systems. Featuring a modular architecture, this product excels in regulating flow rates and managing medium diversion for water, gas, oil and other industrial fluids. Its corrosion-resistant alloy body incorporates hydrodynamic optimization to minimize pressure loss while maximizing throughput efficiency.
Ergonomic design principles are embodied in the anti-slip rotary handle, requiring 15% less operating torque than conventional valves for effortless single-handed adjustment. The multi-layer sealing system with self-lubricating bearings maintains reliable performance across a wide temperature range (-20℃ to 150℃). Surface hardening treatment enhances wear resistance by 40% on critical components, substantially extending service intervals. With flexible installation options (horizontal/vertical) and DN15-DN50 compatibility, it adapts to diverse industrial applications including metallurgical equipment, food processing lines, and marine propulsion systems.
The 34SL20HT series demonstrates exceptional environmental resilience through its salt-spray resistant coating and humidity-proof construction. Safety features include a dual-redundant sealing system and positive-locking mechanism to prevent accidental operation. The quick-disconnect modular design enables maintenance without full pipeline disassembly, significantly reducing downtime. Rigorous endurance testing confirms mechanical durability surpassing 1 million operation cycles, positioning it as a reliable long-term solution for critical fluid control applications.
