SKP55.013U1 Siemens Controller
$1,801.70
The Siemens SKP55.013U1 is a high-performance electro-hydraulic actuator designed for use with Siemens VG series gas valves. It serves as a multifunctional safety component, combining safety shut-off, constant pressure regulation, and air/gas ratio control into a single, compact unit. By monitoring and adjusting the pressure difference across restrictions in both the gas and air supply lines, it ensures a constant air-to-gas ratio regardless of changes in air volume.
Overview
The Siemens SKP55.013U1 is a high-performance electro-hydraulic actuator designed for use with Siemens VG series gas valves. It serves as a multifunctional safety component, combining safety shut-off, constant pressure regulation, and air/gas ratio control into a single, compact unit. By monitoring and adjusting the pressure difference across restrictions in both the gas and air supply lines, it ensures a constant air-to-gas ratio regardless of changes in air volume. This integrated design reduces the complexity, size, and weight of the gas train by eliminating the need for separate upstream constant pressure regulators.
Features
- Combined safety shut-off and differential pressure (ΔP) governor in one unit
- Constant air/gas ratio maintenance even during air flow disruptions
- Compensation for combustion chamber back-pressure fluctuations
- Modular design allows for 360-degree rotation to facilitate easy field wiring and installation
- Visual position indicator and “power on” light for clear operational status
- Spring-return fail-safe closure in less than 0.8 seconds upon power loss
- Slow opening and immediate closing mechanisms to ensure safe burner cycles
- Low power consumption (typical 13.5 VA) for energy efficiency
