SKP25.013U1 Siemens Actuator

Overview

The Siemens SKP25.013U1 is a multifunctional electro-hydraulic actuator designed for use with Siemens VG series gas valve bodies. It integrates safety shut-off and gas pressure regulation into a single compact unit, streamlining gas train design by reducing the number of required components and fittings. This actuator is engineered for industrial and commercial burner applications and is known for its slow opening and immediate closing upon power interruption, ensuring operational safety. It can also function as a 1:1 air/gas ratio regulator or a zero governor when properly configured.

Features

• Integrates safety shut-off and pressure regulation in one unit
• Slow-opening and fast-closing (<0.8 seconds) mechanism for enhanced safety
• Modular design compatible with all VG series gas valve bodies from 1/2-inch to 6-inch
• 360-degree actuator rotation for flexible field wiring and installation
• Visual position indicator and “power-on” light for real-time status monitoring
• Low power consumption (13.5 VA)
• Optional NEMA 4 protection rating with the use of a sealing gasket
• UL listed, FM approved, and CSA certified
