INSTALLATION
Valve may be located in any position. Arrow on
valve body should match direction of flow. Secure
valve with gaskets between flanges and tighten
bolts evenly. Do not use this valve or any component
to align pipes or tighten gap between flanges.
Do not install on inlet side of solenoid valves or
control valves with electric shut-off or shut-off valves
unless a relief valve is used from therein between
piping. Do not install on inlet side of outlet pressure
regulators where liquid may become trapped.
Instead, check valves should be located on outlet
side of these valves. Check valves can be close-
coupled to other matching solenoid valves, pressure
regulators, or strainers by using a Male Adapter
Ring and longer bolts supplied when so specified
on order.
