Product Overview

Remote Overflow Prevention Valve produced by Xuzhou Desheng Petroleum Machinery Co., Ltd. Brand: DESEINOR The remote overflow prevention valve is an underground oil storage tank unloading overflow protection device installed on the oil tank unloading vertical pipe, enabling remote automatic overflow prevention and safe unloading to eliminate oil spill accidents. Core Functions • Automatic Overflow Prevention: When the liquid level approaches the upper limit, the main valve automatically closes to stop unloading. • Remote Control: Allows remote monitoring, testing, and reset without the need for manual operation in the tank. • Small Flow Drainage: After the main valve closes, residual oil in the hose is slowly drained at a small flow rate to prevent residual liquid leakage. • Safe and Reliable: Combines mechanical float ball and spring linkage, independent of electricity, with high stability. • Compliance Protection: Meets gas station safety regulations, preventing overfilling, oil spills, and static electricity risks. Structural Features • Body: High-strength aluminum alloy / cast iron, corrosion-resistant. • Internal: Float ball sensing, mechanical self-locking, bypass flow restriction. • Connection: DN100 standard port, compatible with unloading vertical pipes. • Design: Compact straight installation, easy to install and maintain. Working Principle 1. During unloading, as the liquid level rises, the float ball senses it. 2. Approaching the safe upper limit, the main valve automatically closes. 3. Residual oil in the hose is slowly drained through the bypass small port. 4. After the liquid level drops or is reset, the valve can be reopened. Application Scenarios • Underground oil storage tanks at gas stations • Oil depots, transfer stations • Petrochemical and oil storage and transportation systems Advantages Summary  Safety
