R-30 S Disclaimer This document is an Installation, Operation and Maintenance (IOM) manual for A.R.I. Flow Control Accessories Ltd. (A.R.I.) products. The information enclosed herein contains restricted, privileged, proprietary and confidential information, intended only for usage by authorized A.R.I. technicians. If you are not a qualified technician, you must not take any action in reliance upon this document, unless otherwise permitted in writing by A.R.I.
R-30 S 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.
R-30 S 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.
R-30 S 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.
R-30 S 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.
R-30 S 2.2. Installation procedure Install the valve as indicated by the arrow on the valve bonnet, indicating flow direction [1]. It is recommended to install isolation valves upstream and downstream of the control valve [2]. Close the 2-way outlet ball valve [3B], and turn on the water supply to the valve. Check for leaks;...
R-30 S 2.3. Initial Start-up - The Control Valve Make sure that the upstream and downstream isolation valves are closed [2] and [2A]. Turn off the manual 2-way ball valve at the downstream [3B] port of the valve. Slowly open the upstream isolation valve [2]. Turn on the manual 2-way ball valves of the upstream [3A] and the downstream [3B] ports of the valve.
R-30 S 2.4. Initial Set-up - The Pressure Sustaining Application The following is a general description of the Pressure Sustaining Application: This pressure-sustaining automatic control valve is designed to maintain a minimal preset upstream pressure by releasing excessive pressure to the downstream system. The Eliptix R-30-S valve is a Normally Close Valve (N.C.) that is activated by the line pressure.
R-30 S Make sure that there is a downstream flow demand Make sure that the upstream pressure is higher or equal to the required pressure. Turn the pilot valve’s locking nut (4A) counter clockwise, until it touches the adjusting bolt (4B) head. Make sure all 2-way ball valves (3) are open.
R-30 S 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.
R-30 S 5. TROUBLESHOOTING Problem Cause Check Solution Valve does not open 1. Inlet pressure is too 1. Check the inlet 1. Make sure that the water supply pressure and/or the pump is on. 2. The 2-way outlet 2. Check the state of the 2.
