We have developed modern, reliable and FEM-calculated valve heads, specifically for use as air receiver fittings. These ensure permanent operation (acc. AD2000-S1) on ships, offshore (FPSO) and onshore plants. They can be installed on starting air, emergency air and working air reservoirs, etc., and are available in rated widths of DN 38, DN 50 and DN 80. The shut-off, safety and control fittings are located centrally and in one space-saving housing on the valve head.
