No. 166 MGM Excess Flow Check Valves can be

mounted in any orientation with negligible effect on

flow rate. Each valve will have the proper flow

direction indicated by an arrow stenciled on the

flange. As with all MGM excess flow check valves, the

series 166 is equipped with an orifice in the check

mechanism to allow for pressure equalization and will

reopen automatically after repairs are made.
