TESCOM 44-1300 series pressure-reducing regulator valve

The TESCOM 44-1300 series is a high-pressure, high-flow pressure-reducing regulator with venting and balanced valve designs. It's suitable for applications like commercial diving-breathing air, special gas mix regulation, hard - suit diving, and high - pressure tube trailer gas reduction. Here is a detailed introduction:

Specifications of TESCOM 44-1300 series

Maximum Inlet Pressure: For stainless - steel bodies, options are 4500 psig / 310 bar and 6000 psig / 414 bar. For brass bodies, options are 3750 psig / 260 bar and 5000 psig / 345 bar.

Outlet Pressure Ranges: Include 0 - 300, 0 - 600, 0 - 1000, and 0 - 1500 psig (0 - 20.7, 0 - 41.4, 0 - 69.0, and 0 - 103 bar), with 0 - 2500 psig / 0 - 172 bar also available.

Body Material: Brass, 303 or 316 stainless steel.

Seat Material: The main valve uses CTFE (except for 44 - 13X2 - XXX2, which uses Teflon®). For the vent valve, Teflon® is used for 300 and 600 psig / 20.7 and 41.4 bar outlets, and CTFE is used for 1000 and 1500 psig / 69.0 and 103 bar outlets.

Back-up Rings: Teflon®.

Gaskets: CTFE.

Remaining Parts: 300-series stainless steel, 17-4, 17-7 stainless steel, Teflon®, and brass.

Port Size & Type: 1/2", 3/4" with SAE, NPTF, MS33649, BSPP connections, and 1/2", 1" flanges.

Operating Temperature: - 15°F to 220°F / - 26°C to 104°C.

Flow Capacity: 1/4" main valve has a Cv = 0.8; 3/8" main valve has a Cv = 2.0.

Load Type: Spring, dome, air.

Weight (without gauges): 6.25 lbs / 2.8 kg.

Features of TESCOM 44-1300 series
