Siemens VRD40.xxxUx double valves for use with SKP… electro-hydraulic valve actuators
The normally closed VGDxx.xxxU / VRD40.xxxUx series of modular double-body gas valves combine with SKPx5.xxxU series electro-hydraulic actuators to provide safety shut-off, gas pressure regulation and/or air-gas ratio control for commercial or industrial gas burners.
Compact VRD40… Biogas double-valve bodies consist of two safety shut-off valves in series. Each individual safety shut-off valve has double seats to achieve high flow.
Patented seat construction with individual closing spring for each seat to assure reliable shut-off and high close-off pressure rating.
