Valve Installation
The oil valve installation should be in accordance with standard practices for end
connection selected. Valves with weld end connections are supplied with end
connections of sufficient length to prevent thermal damage to valve internals. As
a safety precaution, methods to thermally block the transfer of heat to the valve
body should be employed during welding.
The end connections should not be
modified to a shorter length.
The weight of the valve must be properly supported
to prevent excessive piping stresses. The valve may be installed in any position,
but the
actuator should be supported when the valve is installed horizontally.
Adequate clearance should be provided for valve maintenance and repair.
CAUTION
Valve must be installed in proper flow direction, per valve
flow tag. Improper installation will result in fuel
contamination of atomizing piping, and improper valve
operation.
CAUTION
Ensure piping upstream of fuel inlet DOES NOT include a
check valve since this will cause hydraulic locking of the oil
valve in the closed position.
