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 1200°F or below 400°F may occur. Do not store
within 50 feet of any source of ozone.
A. INSTALLATION
1. Standard valves may be installed for flow or vacuum in either
direction. Valves with upstream relief hole in ball (V3 option) are
one-way valves. Use care to exclude pipe sealants from the valve
cavity.
2. When installing, use standard gaskets suitable for the specific
service. Tighten flange bolts or studs evenly. Follow ANSI
standards for flange bolt torques.
B. OPERATION
1. The operation consists of turning the handle and/or stem 1 /
4
turn
clockwise to close, and 1 /
4
turn counter-clockwise to open. When
handle and/or stem flats ( 1 /
2
"-1 1 /
2
"), or stop plate pointer and/or
stem groove (2"-10") are in line with the pipeline, the valve is
open. These valves may also be automated.
2. These valves will provide bubble-tight shutoff when used in
accordance with Flowserve's published Pressure-Temperature
Chart.
3. It is not good practice to leave a ball valve partly open (throttling
operation) without knowledge of the pressure drop and flow at
that position. These conditions should be checked with the
Worcester Control Valve Brochure.
4. As shipped from the factory, valves (except oxygen prepared
(V20, V33 or prefix code “X”) and valves with V38 or V46 option)
contain a silicone based lubricant. This is for break-in purposes
and may be removed if it is objectionable for a particular
application by disassembling and solvent washing. Lacquer
thinner will remove the lubricant.
5. Media which can solidify, crystallize or polymerize should not be
allowed to stand in ball valve cavities.
6. Torque Requirements: Operating torque requirements will vary
depending on the length of time between cycles, line pressure,
type of valve seats, and the media in the system. For a detailed
analysis of valve torque requirements, see the Worcester Actuator
Sizing Manual.
NOTE: Media which contain fine powders (25 microns or less) will
significantly raise ball valve torque requirements.
CAUTION:
7. The fluoropolymer body seal (T), the fluoropolymer coated
stainless steel “S” gasket (M), the graphite body seal (Z), and the
Grafoil laminated gasket (G) make excellent seals. However, some
points of caution in their use need emphasizing.
a. No teflon part (except seats) is reusable. Coated stainless steel
“S” gaskets and graphite body seals, and Grafoil laminated
gaskets are also not reusable. Upon disassembly of the valve,
they should be discarded and replaced with new parts.
b. Care must be taken to avoid scratching the fluoropolymer or the
coating of the stainless steel “S” gasket during installation.
Light lubrication of these seals and gaskets can help to prevent
damage.
