2.4 Supplemental Components
e following components are either only required for specic types of Sv, Mv, and Lv Series FM-200®
System arrangements or else may be utilized in dierent capacities or locations depending on the specic
arrangement.
2.4.1 Manifold Check Valve
P/N 18547 (Sv), 18546 (Mv), 18538 (Lv) (See Figure 2.4.1a, 2.4.1b, and 2.4.1c)
In a multiple cylinder arrangement where the slave and primary cylinders share a common manifold or in a
connected main/reserve arrangement, a manifold check valve must be placed between the discharge outlet
and the discharge manifold. e manifold check valve prevents back ow from the manifold should the
system be inadvertently discharged when one or more cylinders are disconnected for weighing or servicing.
e check valve required depends on the Series type of the system. e Sv Series check valve has 1 1/4 in
(32 mm) NPT connections, the Mv Series has 2 in (50 mm) NPT connections, and the Lv Series has 3 in
(80 mm) grooved connections.
