QUICK-CLOSING VALVE SELF-MEDIA OPERATED In addition to the well proven quick closing safety shut-off valves in standard design with actuator controlled by means of instrument air, the self-media operated quick closing valves are used in any application area for which the quick and safe shut-off of gaseous media as well as fuels is required, but auxiliary pneumatic energy for control is not available. As a fully pre-mountend and functional valve unit ready for installation, the self-media operated quick closing valve sets standard in regards to service life and reliability even in the most demanding applications. Applications: Thermal Power Plants, Gas Turbines & Gas Compressor Units, Steelworks, Refineries & Petrochemical Plants, Biogas & Landfill Gas, Pipeline & Gas Distribution Systems, Industrial Combustion YOUR BENEFITS Closing time < 1 sec High safety level through zero leakage Complete, functional valve unit ready for connection – incl. TÜV Type Examination Certificate Heavy duty design for highest number of operating cycles High-performance valve with a extended service life H2-ready OPERATION DETAILS The self-media operated quick-closing valve is equipped with a piston actuator fully suitable to be applied with the geaseous operating medium. A special control system including gas filter, pressure regulator and safety relief valve (SBV) ensures that the operating medium, which is taken off upstream sided, is well conditioned in regards to purity as well as secures the required control pressure.
