Model 115-26TR (Fueling Service) Model 115-26TR Solenoid Control/Check/Thermal Relief Valve Global performance. Personal touch. TOLL FREE 1.888.628.8258 phone: (918)627.1942 fax: (918)622.8916 7400 East 42nd Place, Tulsa, OK 74145 email: [email protected] website: www.controlvalves.com The OCV Model 115-26TR solenoid control valve is designed to open or close in response to an electrical signal. It will also close in the event of a pressure reversal, but will relieve thermal buildup from downstream to upstream. Typical examples include: Process control Petroleum loading terminals SERIES FEATURES Electrically operated solenoid allows valve to open or close Can be maintained without removal from the line Adjustable response speed Factory tested and can be pre-set to your requirements Thermal Relief-relieves thermal buildup from downstream to upstream. Field adjustable Model 115-26TR SCHEMATIC RECOMMENDED INSTALLATION OPERATION A two-way solenoid, when closed, causes the main valve to close. Opening the solenoid opens the valve. The pilot system is equipped with a needle valve that allows the opening and closing speed of the valve to be adjusted. If downstream pressure becomes greater than upstream pressure, the valve will close to prevent reverse flow; however, should downstream pressure increase to the set point of the thermal relief valve (6), this valve will open to relieve the buildup to the upstream side of the valve. COMPONENTS The Model 115-26TR consists of the following components, arranged as shown on the schematic diagram: 1.) Model 65 Basic Valve Assembly 2.) Model 451 Two-Way Solenoid Pilot, N.C. 3.) Model 126 Ejector 4.) Model 141-2 Needle Valve 5.) Model 141-1 Check Valve 6.) Model 684703 Thermal Relief Valve 7.) Model 123 Inline Strainer 8.) Model 155L Visual Indicator ( optional) SIZING Definitive sizing information can be found in the Series 115 section of the OCV Catalog and Engineering section Performance Charts.

Refer to the Dimension Table. Valve should be installed with the bonnet (cover) at the top, particularly 8" and larger valves, and any valve with a limit switch. Shut-off valves should be installed upstream and downstream of the control valve. These are used to isolate the valve during start-up and maintenance. Following main valve installation, the solenoid must be wired into the user's control system. This is a simple two-wire (plus ground) connection. REVISED 12/16/10 Note: Working pressures of solenoids vary greatly, consult factory on application of OCV Model 115-26TR valves.
