Class H insulation system.

Body Material:

Aluminum alloy, die-cast

Strainer:

Fine mesh screen (0.135 in. [0.34 mm] diameter). AISI 303 steel, 
serviceable after removing inlet flange screws. Meets EN161 re-
quirements for strainers

Seals and Gaskets:

Hydrocarbon-resistant NBR and Viton rubber types.

Flange Kit:

Consists of one flange with sealing plug, one O-ring and four
screws. See Table 2.
Note: Valve comes with one kit only.
