Inverted bucket steam traps

For many years Spirax Sarco inverted bucket steam traps have set the standard for performance and reliability. They are among the most robust mechanical trap types and operate using the density difference between steam and condensate. Their stainless steel internal mechanism, robust body construction, strong water seal and inlet check valve make them well suited to demanding steam applications, including superheated steam duties. Different orifice sizes allow matching to pressure and load conditions, and the range covers low, medium and high pressure operation up to 62 barg. They remain a strong option where mechanical simplicity, durability and dependable performance in difficult service conditions outweigh the need for more compact thermostatic or disc-type formats. That positioning keeps them relevant for users who value proven mechanical behaviour over a more compact but less rugged trap style.
