Installation The direct acting PRV VRCD-FF should be installed in horizontal position, especially with if subject to high differential pressure values. Vertical installation if not unavoidable is accepted and won’t affect the PRV performances. The valve has to be installed between two sectioning devices, one upstream and one downstream to allow for maintenance, with a filter upstream of it to prevent dirt from creating malfunctioning. -
Page 6: Maintenance
Maintenance The pressure reducer VRCD-FF is sturdy and reliable, entirely made in stainless steel machined from a solid bar it was designed to minimize maintenance and to tolerate high differential pressures without the risk of cavitation, material wear. A semi-annual visual inspection for the proper movement of the piston and the cleaning of the compensation chamber is recommended. -
