132SPACER RINGMade of a single piece covering the

upper part of the pressure seal gasket.

It is normally manufactured in the

same material as the body.

133GASKET RETAINERIt is made normally of the same

material as the body, and constructed

in four pieces, called segments. The

segments are sized to minimize the

gap between them.

The segmental ring supports all the

forcers transmitted from the bonnet

through the pressure seal gasket and

the spacer ring. It is calculated to

withstand all the force withoutcrac-

king.

134COVER RETAINERDesigned sufficiently resistant to

withstand the forces transmitted by

the cover stud (28).

The cover retainer is normally made

of the same material as the body, but

it can be constructed in any other

material on request. It is machined

tomach exactly with the body, what

guarantees a perfect alignment of the

unit.

17PRESSURE SEAL GASKETThe pressure seal gasket is usually

supplied of compressed

graphite,bordered on the upper and

lower edges with braided filaments of

carbon fiber.

Gasket can also be made in stainless

steel.

25HINGE (ARM)The arm is constructed of the same

material as the valve body. Designed

to swing smoothly, is provided with

an integral mechanical stop, suitably

machined, which contacts the valve

body when the valve is in fully open

condition, and avoids the disc to create

the first contact.

27HINGE PIN (SHAFT)Constructed from a stainless steel

forged bar, is normally designed for

being assembled externally through

the side/s of the valve body, although

internal shaft designs are also available

on request.

In the normal external shaft construc-

tion, one or two cover/s (19A), fitted to

the body with 4 studs (28A) assure a

perfect tightness. Seal between

cover/s and body is achieved by using

spiral wound gaskets (17A).

For some special applications, to

avoidslamming effect, shock

absorbers(dashpots) are installed in

the valve ,connected to the hinge pin

throughstuffing box/es.

1BODYAvailable both in cast and forged steel,

it has been designed to meet all

therequirements of ASME, API and

British Standards.

The body-bonnet connection is made

by a pressure seal gasket. Its pre-

stress condition is achieved by mean-

sof bolts screwed to the bonnet

flange. Ends are normally butt-

welding although they can be also

flanged on request.

All bodies are provided with integrally

cast bosses, located and sized in

accordance with ASME B16.34, which

allow the provision of drain.

3COVERUsually constructed in the same

materials as the body.

6SEAT RINGSupplied in forged stainless steel,

hardfaced with Stellite-6 (2mm of min.

thickness). Seat ring is renewable,

normally welded to the body.

Sealing contact surface is lapped

fora perfect tight seal.

8DISCThe disc is normally constructed in

forged stainless steel for diamters upto

8”, and in cast steel of the same

material as the body for larger sizes.

Contact face is overlayed with 2 mm

minimum thickness of Stellite-6.

It is designed so that the valve can

operate both in horizontal and vertical

positions.

BPE´s y-body (flite-flow) pressure seal

check valves are used to prevent

reverse fluids in lines with high

pressure and/or temperature.

For instance, in boiler aplications, this

valve is used as feed water check

valve, preventing reverse water flow

through the boiler during normal

operation or during boiler shutdown.

Aviailable options

� Equalizer for full disk (this option is

also aplicable to stop-check type).

� Lager sizes on request.

� Flanged or butt-weld ends.

� Full range of body/cover materials.

� Full range of trim materials.

� Meet design of ANSI B16.34, ANSI

B16.5, API 600, BS and DIN.

Design features

��Low pressure drop, approximately 70% less than vertical t-body check

valves (tiliting disc or swing check).

��Low piping cost. In its simplest form, piping cost is contained in the

relationship between size, pressure drop and velocity.

In sizing piping lines the designers would tend to go to the next larger pipe

size when velocities get a little higher than what was considered acceptable.

This would imply an increased piping cost. /LUJL the economic necessity

for minimum pipe sizing, valves of lower pressure drop, and trend toward

higher velocities. Y-body check valves answer this need.
