Bypass valve 12.753 ARI-PRESO DN20 GG-25 PN16 Tmax=+300C flange

ARI-TAKEN 12.750 Bypass valve PN16 Tmax=+450oC flange

 

Bypass valves – these are automatic pressure relief devices, actuated by static pressure arising in front of the valve and characterized by a gradual rise of the spool in proportion to the increase in pressure above the opening pressure. In the bypass valve, pressure stabilization is achieved due to the design of the shut-off element, which eliminates the dynamic effect of the working medium on the movable part of the shut-off element.
