Product Overview
The Siemens VRF Gas Valve series is designed for industrial combustion systems handling biogas, recycling gas, and standard fuel gases. These valves are typically used in burner gas trains where reliable shut-off and controlled gas flow are required.
VRF valves operate as normally-closed two-port valves and are used together with Siemens SKP15, SKP25, SKP55, or SKP75 actuators to perform functions such as safety shut-off, gas pressure regulation, and air-gas ratio control.
The modular design allows the actuator to be mounted directly on the valve body, creating a flexible gas control assembly for different burner configurations. These valves are commonly used in industrial boilers, furnaces, and process heating systems where consistent combustion and safety are critical.

Technical Description
The Siemens VRF series gas valves are normally closed safety shut-off valves designed for industrial combustion systems. These valves are engineered for applications using biogas or recycling gases, where gas composition can vary depending on the process.
When combined with SKP electro-hydraulic actuators, the valve opens slowly during burner start-up and closes rapidly during power loss or safety shutdown. This ensures stable burner operation and prevents unsafe gas accumulation in the combustion chamber.
VRF valves are available in several sizes and are designed to support high gas flow capacity required in industrial burner installations.
