INSTALLATION
Do not put your hands or fingers into the tower or
port areas when the valve cycles.
Do not use higher pressure than rated for the valve.
Higher pressures can cause serious damage to the
valve or harm to operating personnel.
Do not energize the actuator before the valve is
properly attached to the pipeline.
Never use the valve with all flushing ports plugged.
If the medium is harmful in any way, the flushing
port must be piped to a safe location.
4.1
General
Flowrox gate valves are normally delivered fully assembled and ready for use. Only personnel
with appropriate training are allowed to install the valves. If the valve is delivered without an
actuator or accessories, they must be installed in accordance with the manufacturer’s
instructions.
Flowrox gate valves have connections with DIN or ANSI bolt drillings as standard design, but
other drillings are also available, such as BS, AS, JIS.
Reserve enough space for safe installation and maintenance. See
Appendix A
for valve
dimensions. Notice that during opening and closing cycles, a small amount of medium is
discharged in the valve body cavity; therefore do not install gate valves above walkways or
critical components. Flushing and drainage connection must be installed if medium is harmful
or corrosive.
If the valve has been stored in the warehouse, lubricate the valve as instructed in the
Lubrication
chapter.
