26-2300 series

Product catalog summary

Specifications
The TESCOM 26-2300 series is a diaphragm-sensed backpressure regulator designed for high accuracy. It operates under ANSI/ASME B31.3 pressure rating criteria with maximum inlet pressures of 0-50, 0-150, and 0-250 psig (0-3.4, 0-10.3, 0-17.2 bar). The design proof pressure is 150% of the maximum rated pressure, and it ensures bubble-tight leakage. The operating temperature ranges from -40°F to 165°F (-40°C to 74°C), with extended temperatures available upon consultation. The flow capacity is Cv = 0.60, and the maximum operating torque is 25 in-lbs (2.8 N•m).

Materials
The body is made from 303 or 316 stainless steel, or aluminum 2024-t351. The diaphragm and O-rings are made of Buna-n, while the main valve seat and seals are Teflon®. Remaining parts are constructed from 300 series stainless steel.

Cleaning and Weight
Cleaning follows CGA 4.1 and ASTM G93 standards. The stainless model weighs 2.25 lbs (1.0 kg), and the aluminum model weighs 1.25 lbs (0.6 kg).

Features and Benefits
The regulator offers crack to reseat at 2% of set pressure, low torque handknob control, and bubble-tight shutoff at all reseat pressures. It is available in four flow capacities: Cv = 0.60 standard, with optional Cv = 0.06, 0.12, and 1.0. Spring, dome, and air-loaded models are available, and panel mounting is standard. It is compatible with the TESCOM ER5000 electropneumatic controller.

Applications
Suitable for hydraulic or pneumatic testing, calibration, and pump discharge pressure control.

Flow Charts
Flow charts illustrate the relationship between inlet pressure (psig/bar) and flow rate (SCFM/SLPM) for nitrogen, with specific models like 26-2322-24 and 26-2321-24 highlighted.

Part Number Selector
Part numbers are selected based on series, 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 of 0-50, 0-150, and 0-250 psig.

Warning
Users must read and understand the TESCOM Safety, Installation, and Operation Precautions before using the product.
