Worcester Controls

IMPORTANT: Valves intended for ammonia service must be of

stainless (not brass) material, with welded bonnet joint. The standard

bonnet joint is brazed, not welded.

CAUTION: Flowserve recommends that all products 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. INSTALLATION:

CAUTION: Tighten the packing nut before installing valve, due to

creep which occurs after initial assembly.

A. The Worcester Cryogenic Valve is unidirectional for flow in one

direction only and therefore can only be installed in one direction.

With the valve in the closed position, install it with the relief hole

in the ball on the upstream side. The arrow on the stem top or

bonnet will point downstream when the valve is open.

B. The Worcester Cryogenic Diverter Valve must be installed with the

bottom port on the upstream line.

IMPORTANT: DO NOT install valves with extended bonnets with

the extension tilted more than 30° from the upright vertical

position.

The valve is designed to maintain stem seals at normal ambient

temperature. Do not insulate the extension fully — allow 3" – 4" of

tube to protrude above the insulation.

C. To install valves with welded, brazed or soldered pipe ends (BW,

SW, SWO or TE):

NOTES: Prior to welding or brazing, THOROUGHLY CLEAN ALL

JOINT SURFACES to prevent contamination.

Worcester brass valves are of leaded forging brass. Brazing

cannot be successfully accomplished unless a white flux is used.

1. Tack weld valve in place.

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

with ball open. Close the ball and remove the seats, ball and

fluoropolymer coated stainless steel gasket body seals.

(Discard the gaskets when removed from the valve.) Note the

position of the seats so that they can be replaced in the same

position as they were removed.

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 the flame

upon the valve body.

5. Allow the valve to cool and then reassemble with ball, seats

and new gaskets that are included with the valve.

6. IMPORTANT: The fluoropolymer-coated, stainless steel

gaskets that are included with the Worcester

4" – 2"

Cryogenic valves make excellent seals, however, some points

of caution in their use require emphasizing:

a. The gasket body seals are NOT reusable. Upon removal

from valve, they should be discarded and replaced with

new parts.

b. Avoid scratching the fluoropolymer coating of the gaskets

during installation. Light lubrication of these seals can

help to prevent damage.
