Siemens VRD40 Double Valves

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 For use with SKPxx.xxxU Electro-Hydraulic Actuators.   The normally closed VRDxx.xxxUx series of modular double-body gas valves combine with SKP… series electro-hydraulic actuators to provide safety shut-off, gas pressure regulation and/or air-gas ratio control for commercial or industrial gas burners. Application: All VRD40.xxxUx valves can be combined with any SKPxx.xxxUx series actuator. The actuator can be mounted while the valve is installed and under pressure. SKPxx.xxxUx regulating actuators are applicable for both low and high supply gas pressure applications, eliminating excessive regulator inventories. Maximum pressure ratings vary with valve size. All VRD40.xxxUx valves perform
