J20728 - 04/07 - Subject to change. © Belimo Aircontrols (USA), Inc. 2.16 CONTROL VALVES ® A. Control Valves: Factory fabricated of type, body material, and pressure class based on maximum pressure and temperature rating of the piping system, unless otherwise indicated. B. Pressure Independent Control Valves a. Manufacturers: i. BELIMO AIRCONTROLS (USA), INC. b. The modulating control valves shall be pressure independent. c. The control valves shall accurately control the flow from 0 to 100% full rated flow with an equal percentage flow characteristic. The flow shall not vary more than +/- 5% due to system pressure fluctuations across the valve with a minimum of 5 PSID across the valve. d. Forged brass body rated at no less than 400 PSI, chrome plated brass ball and stem, female NPT union ends, dual EPDM lubricated O-rings and TEFZEL characterizing disc. e. Combination of actuator and valve shall provide a minimum close-off pressure rating of 200 PSID. f. The control valve shall require no maintenance and shall not include replaceable cartridges. g. All actuators shall be electronically programmed by use of a handheld programming device or external computer software. Programming using actuator mounted switches or multi-turn actuators are NOT acceptable. [Actuators for 3-wire floating (tri-state) on 1/2” – 1” pressure independent control valves shall fail in place and have a mechanical device inserted between the valve and the actuator for the adjustment of flow.] [Actuators for two-position 1/2” – 1” pressure independent control valves shall fail in place and have a mechanical device inserted between the valve and the actuator for the adjustment of flow.] [Actuators shall be provided with an auxiliary switch to prove valve position.] h. The actuator shall be of the same manufacturer as the valve, integrally mounted to the valve at the factory via a single screw on a four-way DIN mounting-base. i. The control valve shall require no maintenance and shall not include replaceable cartridges. j. The manufacturer shall warrant all components for a period 5 years from the date of production, with the first two years unconditional. k. The use of pressure independent valves piped in parallel to achieve the rated coil flow shall be permitted. Actuators shall be electronically programmed to permit sequencing the flow with a single control output point. The use of external devices to permit sequencing is NOT acceptable. Specifying Pressure Independent Characterized Control Valves (1/2” – 2”) Specifying Pressure Independent Characterized Control Valves Master Format To be inserted into Section 15900 – HVAC Instrumentation and Controls To be inserted into Section 15181 – HYDRONIC PIPING 2.6 CONTROL VALVES K. Calibrated Balancing Valves and Automatic Flow-Control Valves shall not be required on devices where pressure independent control valves are installed. NOTE TO BE ADDED TO THE PIPING DETAIL: Strainers shall not be required in front of each pressure independent control valve. A Type 20 strainer (or equivalent) should be installed in the system, in additional to other system strainers. To be inserted into Section 15950 – TESTING, ADJUSTING, AND BALANCING 3.11 PROCEDURE FOR HYDRONIC SYSTEMS [CHOOSE ONE OF THE FOLLOWING TWO PARAGRAPHS] H. Systems installed with pressure independent control valves shall not require hydronic system balancing. H. Systems installed with pressure independent valves shall require verification of flow for [10%] [20%] [25%] of the total installed product. Exact locations of tested product to be coordinated with the design engineer. 75
