Safety proportional spring valve ARI-SAFE 12.921 DN32*32

Safety proportional spring valve ARI-SAFE 12.921 DN32*32

The degree of opening changes in proportion to the amount of excess pressure over the set pressure. Full opening is achieved when the pressure is exceeded by 10%. With this series of valves, the diameter of the outlet pipe is equal to the diameter of the inlet pipe.

Features of ARI-SAFE safety valves:

• Full lift and proportional;
• Abrasion resistant seat and disc;
• Valves can be made with stainless steel or EPDM bellows, which eliminates the influence of back pressure, as well as contamination of the working environment;
• Versions with elastic seal available;
• Precision execution of the disk and guides;
• Built-in trigger sensor;
• Possibility of completing with a metal rupture disc when used in super-aggressive environments.
