Series 608 Ball Valve

CAUTION: Flowserve recommends that all

product which must be stored prior to installation

be stored indoors, in an environment suitable for

human occupancy. Do not store product in areas

where exposure to relative humidity above 85%,

acid or alkali fumes, radiation above normal

background, ultraviolet light, or temperatures

above 120°F or below 40°F may occur. Do not

store within 50 feet of any source of ozone.

1.0 INSTALLATION

1. 608 valves may be installed for flow or vacuum

in either direction. Use care to exclude pipe

sealants from the valve cavity. Valves with

upstream relief hole in ball (V3 option) are one-

way valves.

2. Weld End Valves (TE, SW, BW): NOTE: Prior

to welding , THOROUGHLY CLEAN ALLJOINT

SURFACES to prevent contamination. Valves with

“PG”, “RG”, “XG”, “AG”, and “GG” seat and body

seal combinations and V67 option code are

compatible with welding temperatures. Therefore,

these valves are weld-as-is and do not have to be

disassembled to be welded in the line. These

valves will have a red welding tag attached. If

these valves are disassembled, the graphite-

coated stainless steel gasket body seals and the

seat back seals (used with “A” or “G” seats only)

must be replaced. When welding these valves, the

ball must be open to prevent adhesion of weld

spatter to the ball. Use STICK or MIG welding,

and allow valve and joint to cool to the touch

between passes. For all other weld valves:

a. Tack weld valve in place.

b. With valve open, remove three body bolts,

loosen fourth and swing out body. Remove fourth

bolt and spread pipe ends Close valve, remove

ball, seats, body seals. Return body to its original

position and temporarily secure it with two body

bolts diagonally opposite each other.

c. Weld valve in line.

d. Allow valve to cool, reassemble valve. Install

new body seals, if they were shipped separately

from the valve. Temporary Buna body seals, if

found in the valve as received, are not to be

reused. If coated stainless steel “S” gasket body

seals are used (Code M or G), the wide flange of

the “S” gasket must face the valve body. See

View A-A detail on page 5.

e. Tighten and torque body bolts evenly and

diagonally opposite each other, alternating in a

criss-cross pattern. Use torque figures below:

Note: Stainless steel bolts and nuts are generally

used in all three-piece valves with stainless steel

bodies.

CAUTION: The fluoropolymer and UHMWPE

body seals (codes T and U), and the coated

stainless steel gaskets (codes M and G) make

excellent seals. However, some points of

caution in their use need emphasizing.

a. No fluoropolymer or UHMWPE part (except a

seat) or seat back seal is reusable. Coated

stainless steel gaskets are also not reusable and

cannot be used in stainless bodies with cast

surfaces or serrations in body seal area. Upon

disassembly of the valve, these seals or gaskets

should be discarded and replaced with new parts.

b. Care must be taken to avoid scratching the

fluoropolymer or UHMWPE seals or the coating of

the stainless steel gaskets during installation.

Light lubrication of these seals can help to prevent

damage.
