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.
