FUJIKIN - Check Valves

Features:

Fixed Cracking Pressures

Applicable Fluid
Air, Nitrogen gas, Inert gas like Helium, and non - corrosive gas and liquid.

Cracking and Reseal Pressures at 70 °F (20 °C)
※ 1：Inlet pressure at the beginning of flow The beginning of flow refers to a flow that produces continuous bubbles from the outlet side when the outlet piping is placed in water and pressurized from the inlet side.
※ 2：Pressure when the flow is no longer confirmed. [Claking pressure (nominal): 0.003 to 0.035 MPa] Reverse pressure according to cracking pressure is required for the seal of the valve seat, respectively. Reverse pressure is the pressure obtained by subtracting the inlet pressure from the outlet pressure. [Clacking pressure (nominal): 0.069 to 0.18 MPa] If the inlet pressure falls below the value shown in the table, the valve seat is resealed.
