K41 / K42 / K43 - Dome Loaded Pressure Regulators
Robust dome-loaded regulators delivering precise pressure control for gas and liquid applications.
Balanced valve design ensures stable pressure regulation.
Corrosion-resistant nodular iron construction enhances durability.
Low-pressure version improves sensitivity for precision control.
Features
The K40 Series dome-loaded pressure regulators provide accurate control for low to medium delivery pressures. Their balanced valve design minimises pressure fluctuations, ensuring stable regulation even with varying inlet conditions. Available with internal or external dome loading, they eliminate the need for a pilot regulator in gas applications. A low-pressure variant enhances sensitivity below 5 barg for improved precision. Built from durable nodular iron, the K40 Series withstands demanding environments. Designed for use with gas and liquid media, they support multiple elastomer options for varied temperature conditions. Ideal for gas supply systems and liquid pressure control applications.
