Installation Requirements
Inlet isolating valves (full flow type) must be installed close to the DRV40 for ease of
maintenance. It is recommended that outlet isolating valves (full ow type) are also installed.
The use of supply / return strainers will reduce debris entering the DRV40. The recommended
mesh aperture dimension = 0.5 mm.
Inlet pressure tappings which allow measurement of the inlet pressures to the DRV40 under
operating conditions are particularly recommended for in-service testing.
Pipework must be rigidly supported to avoid any strain on the connections.
Make sure the pipe layout will avoid the build up of trapped air in the system. Air release valves
can be used where this is not possible.
Inlet and outlet threaded joint connections should be made with PTFE thread sealing tape or
liquid sealant. Do not use oil-based, non-setting joint compounds.
To eliminate pipe debris it is essential that supply pipes are thoroughly ushed before
connection to the DRV40.
