Features

Low-pressure setting and fast speed of response –

T205 Series regulator has a low-pressure setting as

low as 1 in. w.c. / 2.5 mbar. It can respond quickly to

downstream  ow demand and pressure changes due to

direct-operated structure.

Accurate control and small lockup pressure – Large

diaphragm area provides very accurate throttling control

at low pressure settings. An added bene t of lever style

regulator is that it can shut off the process  uid using small

lockup pressure.

Multiple applications – T205 Series regulator can be used

for a wide variety of gases including air, nitrogen, natural

gas, sour gas (NACE Construction), butane and propane.

Corrosion resistance – Multiple regulator constructions

are available in a variety of materials for compatibility with

corrosive process gases.

Easy conversion between constructions – Converts

easily from the Type T205 to the Type T205M with two

O-rings and one machine screw.

Sour gas service capability – Available construction to

meet NACE MR0175-2002.
