Siemens VKP Proportioning Gas Valves

Siemens VKP valves are proportioning gas valves designed for precise modulation and continuous control of gas flow in industrial combustion systems. They are specified in applications where variable gas flow is required, rather than simple ON/OFF shut-off.

VKP valves are used as control elements within a gas train, supporting stable combustion and accurate gas–air ratio control in conjunction with the wider combustion control system.

Typical Applications

• Proportional gas flow control
• Combustion systems requiring continuous modulation
• Ratio-controlled industrial burners
• Gas trains incorporating separate safety shut-off valves

Valve Function and System Role

Siemens VKP valves are designed to regulate gas flow proportionally in response to control signals from the combustion management system. Unlike safety shut-off valves, VKP valves are not intended to provide primary gas isolation.

For this reason, VKP valves are typically installed downstream of dedicated safety shut-off valves such as Siemens VGG or VGD valve bodies. This separation of safety and control functions supports safe and stable system operation.

Integration with Siemens Combustion Systems

VKP proportioning valves are commonly used as part of integrated Siemens combustion systems, working alongside safety shut-off valves, SKP actuators, pressure switches, and burner management controls.

Correct system design ensures that safety shut-off and modulation functions are handled by the appropriate components within the gas train.

Available Valve Sizes and Specifications

Siemens VKP valves are available in a range of sizes and configurations to suit different industrial combustion requirements. Detailed technical specifications for each VKP valve model are provided within the individual product listings below.

Selection and Replacement Guidance

When selecting or replacing a Siemens VKP valve, the required control range, valve size, and system compatibility must be confirmed to ensure correct operation.

If you are unsure whether a VKP proportioning valve is suitable for your application, or if a different Siemens valve type is required, technical confirmation is recommended before ordering.
