Siemens Combustion Controls

Siemens SKP actuators combine with Siemens VG valve bodies to provide gas safety shutoff, pressure regulation and air/gas ratio control. Easy to assemble and install, Siemens gas valves offer outstanding performance in a compact package.

On/off/ratio control Double diaphragm ratio regulator Compensates for variance in combustion chamber pressure Ideal for applications with preheated combustion air
	Safety shutoff operation Proof-of-Closure (POC) switch to ensure safety Modular design and quick connect wire terminals Extremely low 13.5 VA power consumption Power on indication LED Visual position indication (VPI)
All of the SKP15 features plus… Pressure regulation to 20 PSI Accurate pressure control with zero droop Applicable as a 1:1 ratio regulator or zero governor
	½” – 3” threaded single valves 1” – 3” threaded double valves 2½” – 6” flanged double valves 1½” – 6” bio gas double valves

From the ultra-precise, linear flow control found in the VKP proportional control valve to the extremely repeatable, cost effective VKG/VKF butterfly valves; VK valves provide the control required in combustion applications.

1 ¼” – 8” sizes Full and reduced port Compatible with ANSI or DN flanges
	Profiled cylinder provides linear change in flow across angular rotation ½” – 2” sizes Separate NPT flanges allow mounting flexibility Direct connection to a VGD20 shut-off valve SQM33/40/45 actuator mounts directly to valve
Full, medium and reduced port versions ½” – 4” NPT; UL approved ½” – 3” Rp; CE approved Up to 25 psi pressure ratings Cycle tested and certified from -40 to 160°F Manual adjustment versions Clear position indication Limiting orifice valve models VRG… for bio gas applications

Siemens SQM actuators deliver precise control and multiple user-friendly features. Available as stand-alone actuators or assembled to control valves; SQM actuators are the best solution for precise flow control applications.
