VGG Series Valves

Operation

All VGG10.xxxU gas valves are normally closed, two-way valves. The valves have a standard,
integral, stainless steel mesh filter (0.9 mm) in the inlet to protect the downstream
components against contamination.
VGG10.xxxU series gas valves have a contoured valve disc for stable regulating control and
smooth release (see Figure 1).
