Page 4: Safety Instructions
R-20 RM 1. SAFETY INSTRUCTIONS General A.R.I. products always operate as components in a larger system. It is essential for the system designers, installers, operators and maintenance personnel to comply with all the relevant safety standards. Installation, operation or maintenance of the product should be done only by qualified workers, technicians and/or contractors using only good engineering practices, complying with and observing all conventional safety instructions in order to minimize risk and/or danger and/or hazard to workers, the public or to property in the vicinity in accordance with all relevant local standards. -
Page 5: Installation
R-20 RM Installation Install the product according to the detailed Installation Instructions provided with it by A.R.I. and according to the description given in this manual. The user should install manual Isolation Valves at the valve's upstream and downstream ports. In all installation sites, the user should enable good visibility and verify that the work and auxiliary equipment used are done in accordance with the relevant local authorized standards. -
Page 6: Before Returning To Regular Operation
R-20 RM Before returning to regular operation Re-assemble any protection covers or protection mechanisms removed during service or maintenance operations. Make sure that all the tools, ladders, lifting devices, etc. used during the maintenance procedures are taken away from the product area and stored. Remove grease and fat material residues in order to avoid slipping. -
Page 7: Installation
R-20 RM 2. INSTALLATION 2.1. Pre installation requisites Important: Before performing any work on the valve make sure that all workers on site are familiar with the safety instructions and the relevant local and general safety instructions and work regulations. Before installing the valve, flush the pipeline to remove scale, dirt and other particles that might affect the valve performance. -
Page 8: Installation Procedure
R-20 RM 2.2. Installation procedure Install the valve as indicated by the arrow on the valve bonnet, indicating flow direction [1]. In addition of the control valve it is recommended to install the following valves: Isolation valves upstream and downstream of the control valve [2] & [2A]. Air valves upstream and downstream of the control valve [5]. -
Page 9: Initial Start-Up - The Control Valve
R-20 RM 2.3. Initial Start-up - The Control Valve Make sure that the upstream and the downstream isolation valves are closed [2] and [2A]. Slowly open the upstream isolation valve [2]. Check for leaks; tighten bolts & fittings, if necessary. Turn the 3-way selector [3] to its “AUTO”... -
Page 10: Initial Set-Up - The Pressure Reducing Application
R-20 RM 2.4. Initial Set-up - The Pressure Reducing Application The following is a general description of the Pressure Reducing Application: This pressure-reducing valve is an automatic control valve designed to reduce a higher upstream pressure to a preset lower downstream pressure, and to maintain this constant pressure regardless of flow-rate or upstream pressure fluctuations. -
Page 11: Operation Instructions
R-20 RM 3. OPERATION INSTRUCTIONS To manually open the valve, turn the manual 3-way selector [ ] to its "OPEN" position. Please note: By doing so you will have no control over the downstream pressure; it is possible that your system will be exposed to excessive pressure. -
Page 12: Maintenance
R-20 RM 4. MAINTENANCE Under regular operation A.R.I's valves require minimal maintenance and no lubrication, however in freezing climates the valve should be dismantled and drained for the winter months. 4.1. Periodic Inspection Every 6 months visually inspect the valve's diaphragm for any tears. Every 12 months inspect the valve's operation and clean the Finger Filter. -
