Each

 

VGD20.xxxU

 

double

valve

 

requires

 

2

 

threaded

 

mounting

 

flanges

 

(AGFxx.xxU).

 

Each

 

flange

 

includes

 

the

 

necessary

 

installation

 

hardware

 

(bolts,

 

nuts

 

and

 

O

‐

ring).

 

Each

 

mounting

 

flange

 

has

 

a

 

¼

tap.

 

The

 

flanges

 

can

 

be

onto

 

the

 

pipe,

 

and

 

then

 

bolted

 

onto

 

the

 

VGD20.xxxU

 

gas

 

valve

 

body.

 

This

 

feature

 

eliminates

 

the

 

use

 

of

 

pipe

 

unions

 

and

 

permits

 

the
