Emerson Fisher's Type C404-32 is used widely on transport trucks and large storage tanks, the 4 in. (DN 100) flanged unit comes standard with all stainless steel construction for maximum protection against rust and corrosion. For easy field maintenance, the seat ring is field replaceable. Type C404-32 flanged internal valve has gained wide field acceptance for use as primary shutoff valve, excess flow valve and back check valve. The valve can be used in conjunction with or without pumps and compressors. Because of the integral back check function of this valve, selective filling of manifold storage tanks requires the use of additional shutoff valve.
The Type C404-32 is the only internal valve that cannot be opened and closed by the Type P650 cable control.
Note: Closing flow vertical down
