Sulzer Mixpac Q-System Cartridges For most cartridges, we can offer several piston designs such as solid pistons, weldable pistons and self-bleeding valve pistons. With the self-bleeding valve technology we offer a unique and outstanding technology to remove trapped air during insertion of cartridge pistons. This patented system has set a new standard in the industry. Buying cartridges is a matter of confidence, because cartridges must be leak free from -10°C to +50°C today, tomorrow and in years to come.
