The K31 / K32 / K33 Dome Loaded Pressure Regulators provide precise and stable pressure control in gas and liquid applications. With internal and external dome loading, they ensure stable delivery pressure even under varying inlet conditions. The balanced design optimises performance, particularly at low delivery pressures below 5 barg, while external sensing enhances flow capacity. Constructed from stainless steel or nodular iron, they withstand demanding industrial conditions. Offering multiple port sizes, material options, and outlet pressure ranges up to 70 barg, these regulators meet a range of system requirements. Leakage-tight performance and helium leak testing ensure superior reliability and safety.
