Siemens VGG Gas Valve Body

(21 products)

The Siemens VGG single body gas valves are designed to be combined with the SKP range of actuators. They are configured as normally closed and provide safety shut-off, gas pressure regulation and/or air-gas ratio control for commercial or industrial gas burners.

Application

All VGG valves can be combined with an SKP actuator. The actuator can be mounted while the valve is installed and under pressure. SKP regulating actuators are applicable for both low and high supply gas pressure applications.

All VGG valves perform these functions in combination with each of the following actuators:

SKP15 Safety shut-off
SKP25 Safety shut-off and constant pressure regulation or zero governor
SKP55 Safety shut-off, pressure regulation and differential pressure air-gas ratio control
SKP75 Safety shut-off, pressure regulation and adjustable air/gas ratio control

 

Since more than one function can be performed by a single valve, fewer components and fittings are required, significantly reducing both the size and weight of the gas train. In addition, smaller diameter gas valves can be used.
