Installation, Operation and Maintenance Instructions

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.

I. INSTALLATION

A. Standard 94 Series three-piece and flanged one-piece 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.

B. When installing 94, AF94 or FZ94 flanged one-piece valves, use

standard gaskets suitable for the specific service. Tighten flange

bolts or studs evenly. Follow ANSI standards for flange bolt

torque.

C. For Weld End Valves (SW, BW):

NOTES: Prior to welding, THOROUGHLY CLEAN ALL JOINT

SURFACES to prevent contamination.

Valves with “PG”, “RG”, “XG”, “AG” and “GG” seat/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 line. A red welding tag

will be attached to the valve. If these valves are disassembled, the

graphite-coated stainless steel gasket body seals (code “G”) 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 End Valves:

1. Tack weld the valve in place.

2. Remove three body bolts, loosen the fourth and swing out the

body with valve open. Close the valve and remove the seats,

ball and body seals.

NOTE: FZ94 valves can not be swung out. Remove fourth bolt

and spread pipe ends to clear centering ring (Revision R3

FZ94 valves with “G” seats, and all Revision R4 and later

FZ94 valves do not have centering rings). Close valve, remove

ball, seats, body seals.

3. Swing body in and secure it with one additional body bolt

diagonally from first.

4. Weld pipe ends. When gas welding, DO NOT play flame on

the valve body.

5. Allow valve to cool. Reassemble valve. Install new body seals,

or coated stainless steel “S” gaskets (code M or G), if they

were shipped separately from the valve, discarding the

temporary Buna body seals found in the valve as received.

See I.D.3.
