VOG15.011U1 Siemens Valve

Overview

The Siemens VOG15.011U1 is a high-reliability, electro-hydraulically actuated oil safety shut-off valve designed for industrial and commercial burner systems. This versatile valve can be configured for either 2-way safety shut-off or 3-way recirculation, making it ideal for managing heavy fuel oils. It is engineered to open slowly when powered and close rapidly in less than one second upon power interruption, ensuring a critical safety interlock between the burner and the fuel supply.

Features

• Proof-of-Closure (POC) with over-travel verification ensures the valve is fully seated
• Dual-mode capability allows for standard shut-off or 3-way recirculation with a provided NPT plug
• Rapid safety shutdown closes the valve in under one second on loss of power
• Visual position indicator and integrated “power-on” status light for local monitoring
• Field-rotatable actuator (360 degrees) and quick-connect terminals simplify installation
• Durable brass body with stainless steel internals and high-temperature PTFE seals
• Low power consumption (approximately 20 VA) during continuous operation
