Ordering Information

Description

Series 76 ISO-Universal flanges and components in this

catalog are made of type 304 stainless steel. Centering

ring and seal assemblies are offered with an aluminum

centering ring and spacer ring, or with a stainless

centering ring and an aluminum spacer ring. Rotatable bolt

rings and clamps are made of aluminum alloy. Retaining

rings are made of steel.

Flange seal surfaces are carefully machined and inspected

for defects. They are cleaned and packaged to remain

clean and protected in shipping. The user should observe

precaution as required to prevent seal surface harm. This

is especially important for used components returned to

storage.

Installation

The Series 76 ISO-Universal flange components can be

connected in various ways. The figures below illustrate

some possibilities. Figure 2a shows a pair of MF flanges

retained by double claw clamps. This is usually the most

economical arrangement. In Figure 2b an MF flange with

a rotatable bolt ring is joined to a bolted flange using nuts

and bolts. In Figure 2c an MF flange is joined to a tapped

bolt flange using single claw clamps. Tapped flanges are

found on some valve bodies. Alternatively, a rotatable bolt

ring could have been used with an MF flange to obtain the

same result shown in Figure 2c. Last, Figure 2d shows a

pair of bolted flanges joined in the usual way by nuts and

bolts.

In attaching a rotatable bolt ring to an MF flange as in

Figure 2b, the ring is first passed over the flange with the

larger bore of the ring facing outward from the open port.

The split retaining ring is then snapped into the groove on

the periphery of the MF flange. Then the bolt ring is pulled

forward into position. Pairs of bolted flanges may also be

used.
