Model 900 -Options for 900 Safety Relief Valve Test System

SAFETY INTERLOCK on hydraulic clamping circuit that will lock test pressure and not allow it to dump if the hydraulic system fails.

SAFETY SHIELD between clamp fixture and control console.

API-527, SEAT LEAKAGE FIXTURE for Safety Relief Valve outlet flange. Fixtures are aluminum and easily clamped and removed from the SRV outlet flange. Includes a Bubble Jar to ANSI B16.104. The size range is 2” – 150/300# to 12” – 150/300# ANSI pressure class.

DATA ACQUISITION AND ANALYSIS SYSTEM (DAAS) measures pressure and time with PC based hardware and software. The test data is read from transducers or other sensors and fed back to a CPU for processing by the system. The DAAS is configured to uniquely defined application requirements and will acquire, analyze and present the test data in real time. The test results can be stored by a unique test number assigned by the DAAS system or by the valve serial number. The results can be stored on a Flash Memory Stick, downloaded to the CPU, downloaded to a Laptop or sent to a Server. This DAAS software is LAB VIEW based and user friendly. LAB VIEW is a worldwide trade name and the software and hardware can be serviced by local LAB VIEW representation if necessary. Our screens are custom designed to reflect customer requirements.

LINEAR VALVE DISPLACEMENT TRANSDUCER (LVDT) To measure SRV stem lift and transmit the results to the DAAS system.

MUFFLER/SILENCER Model SV-3000, Silencer assembly for air/gas SRV testing. The system is self contained and is mounted on wheels. The assembly can also raise and lower to reach the outlet of the SRV being tested. There are seven (7) 20” long adapters (2”, 3”, 4”, 5”, 6”, 8” & 10”) to connect from the SRV outlet to the silencer.

PILOT VALVE CIRCUIT to actuate air operated pilot safety relief valves.

VACUUM TEST CIRCUIT to 28.5 Hg /0.7 psia / -14 psig. The vacuum circuit has a separate seal plate, digital gauge, vacuum pump and transducer.

3,000, 5,000 or 6,000 psi AIR COMPRESSOR 5, 7.5 or 10 HP, 460 volt / 3 phase / 50 or 60 Hz
