Veriflo offers a variety of diaphragm valves with various inlet connections,
outlet connections, and actuators and other options. Before installing the
valve you should fully understand the options of your particular valve and its
suitability for the application.
Step 1
Verify that the valve is rated for the system operating pressures and has the
proper connections and options for the type of gas and pressures required for
your application.
Step 2
Inspect the valve and your system connections for evidence of contamination
or damage. Valves that are damaged or contaminated should not be used.
Step 3
The fluid supplied to the valve must be clean. Contamination can damage the
valve’s seat and cause a leak.
Step 4
Inlet and outlet connections may be identified by an arrow marked on the
body for 2 port valves or by “IN” and “OUT” marking on multiple port valves.
Step 5
Securely tighten connection fittings in accordance with procedures
recommended by the fitting manufacturer or appropriate industry standards.
Step 6
Perform leak tests to verify there are no leaks to atmosphere or across the
valve seat. Leak test methods should be appropriate for the system leak
integrity requirements.
Step 7
Follow all applicable safety and maintenance procedures for your system
before applying system pressure.
Step 8
The valve is now ready for operation.
