Ralston Instruments has expanded its line of DP pressure transmitter adapters to fit a larger number of manufacturers’ block and bleed valves and manifolds. The DP transmitter adapters fit the following 3 and 5 valve manifolds: Rosemount 2051, 3051 series DP pressure transmitters; Yokogawa EJ series DP pressure transmitters; Endress+Hauser Deltabar PMD55 and PMD75 transmitters; and, Honeywell Smartline ST700 and ST800 pressure transmitters.

Additionally, the company has also added several bleeder screw adapters for Rosemount, Noshok and PGI block and bleed valves that connect pressure transmitters to the process.

These adapters thread into the block and bleed valve where the bleeder screw normally goes. They can then be used to pressurize a transmitter for calibration and testing after it has been isolated from the process.

The Ralston Instruments bleeder screw adapters fit the following valves: Rosemount 306 In-line manifold adapters; Rosemount Anderson Greenwood M25 and M251 Block and Bleed gauge valve adapters; Noshok 600 Series, 700 Series, 2070 Series, 2170 Series Block and bleed valve adapters; and, Parker PGI V-526 and V-527 Bleeder Screw Gauge Valve adapters.
