SAFETY RELIEF VALVE TESTER Brief History: Dunn's Valve Testers Inc have been manufacturing Valve Testers since 1978. We were the first to introduce valve testers and set the standard for all valve testing. We strive to maintain that level of Durability Value and Technology well into the future. Our Valve Testers provide a method of accurately and speedily testing valves at a relatively low cost per unit and designed with the test operator in mind. MODEL - Key Features • All valves are clamped eliminating possible distortion, breakage or false tests • Valves and Vessels with threaded connections are mounted into place using a threaded flange adaptor. • Using quick dynamic of hydraulic accusation secures the valve on the uniquely designed table of pressure seals immediately, saving on setup and breakdown • The compact design occupies a work area of less than 15 square feet • Patented Hydraulic Clamp Arms and Stainless Seal Plate #xxx1038; xxx2227 • Safety Hydraulic Interlock to prevent loss of sealing force during test • Regulated High Pressure Air Inlet for seal tightness test • 3000 PSI Hydrostatic test capability BUILD SPECIFICATIONS Our Relief Valve Tester machines accurately lift relief valve disc and allows the valve to reseat without damage. Our machines come in varies sizes depending on the size of the valves and pressures to be applied. • Valve Types - Gates ; Globes ; Plug ; Ball; Butterfly • End Connections - Flange ; Butt Weld; RTJ ; RF; S/E; S/W; WAFER NOTE: Each unit is adapted and built to specific client requirements from these base models Optional Extras Available - NPT Threaded Adapter Set, Data Acquisition System, Rapid Recycle System, Safety Shield, High Pressure Storage (ASME & DOT), Regulated Air and Hydraulic System for filling, draining, venting and testing, up to 30,000 PSI test pressure can be added, Air Test, Auxiliary Port, Seat-Tightness and Back-Pressure test clamps, High Pressure Air compressor up to 6400 PSI, Higher Test Pressure Capability, Test System for Pilot Operated Valves Email - [email protected] Telephone - 281 350-4767 CONTACT - Dunn's Valve Testers Inc.
