26-2300 SERIES

Product catalog summary

Specifications
The 26-2300 Series regulator is designed according to ANSI/ASME B31.3 standards. It has a maximum inlet pressure range of 0-50, 0-150, and 0-250 psig (0-3.4, 0-10.3, 0-17.2 bar) with a design proof pressure of 150% of the maximum rated pressure. The regulator ensures bubble-tight leakage and operates within a temperature range of -40°F to 165°F (-40°C to 74°C). For extended temperatures up to 400°F (204°C), consultation with TESCOM is recommended. The flow capacity is Cv = 0.60, and the maximum operating torque is 25 in-lbs (2.8 N•m).

Materials
The body is available in 303 Stainless Steel, 316 Stainless Steel, or Aluminum 2024-T351. The diaphragm is made of Nitrile, Buna-N, and the main valve seat is PTFE. O-rings are also Nitrile, Buna-N, and seals are PTFE. Remaining parts are constructed from 300 Series Stainless Steel.

Cleaning and Weight
The cleaning standards are CGA 4.1 and ASTM G93. The weight of the stainless model is 2.25 lbs (1.0 kg), and the aluminum model is 1.25 lbs (0.6 kg).

Features and Applications
The TESCOM 26-2300 Series is a diaphragm-sensed backpressure regulator that controls pressures up to 500 psig (34.5 bar) and offers flow capacities (Cv) from 0.02 to 1.0. It is suitable for hydraulic or pneumatic testing, calibration, and pump discharge pressure control. Key features include a crack to reseat pressure of 2%, low torque handknob control, bubble-tight shutoff, and compatibility with the TESCOM ER5000 Electropneumatic Controller. It is available in spring, dome, and air-loaded models with standard panel mounting.

Flow Charts
The document includes flow charts for different models, illustrating the relationship between inlet pressure (psig/bar) and flow rate (SCFM/SLPM) for nitrogen. These charts are essential for understanding the performance characteristics of each model.

Part Number Selector
The part number selector provides a guide for choosing the appropriate regulator configuration based on body material, control pressure range, inlet and outlet port type, and size. Options include 303 Stainless Steel, 2024-T351 Aluminum, and 316 Stainless Steel, with pressure ranges from 0-50 psig to 0-250 psig and various port types and sizes.
