Gate Valve - BH5 Series

These valves, by virtue of the venturi-type flow path,

offer the combined advantages of maximum flow

efficiency and ease of operation. These are meant for

high pressure-high temperature applications and are

available in Carbon steel and Alloy steel materials.

While the stems of carbon steel valves are of 13%

chromium stainless steel, those of alloy steel valves are

made from 16% chromium special stainless steel, for

high temperature and anti-corrosion properties. The

wedges are of two piece construction held together by a

pin, offering flexibility. This combined with the mirror

finish lapping ensures perfect sealing and compensates

for wear in the long run. These valves are provided with

pressure seal (self-seal) bonnet to provide better third

port seal. Thrust ball bearings enable the valve to be

operated with minimum effort.

These Valves find their application in high

pressure and high temperature lines where the

end connections are to be made by butt-welding. It

is recommended for on/off services ; and the

media to be handled are water, oil, gas, steam or

other non-corrosive ones.

Edge Preparation

Pressure Seal

BHEL standard valve body is designed in

accordance with ASME B 16.34.

BHEL standard inside diameter is decided based

on ASME B 16.34 or connecting pipe size.

BHEL standard edge preparation is in accordance

with ASME B 16.25. Any other preparations,

however, are also available to order.

Sealing surface on both body and bonnet is

overlaid with austenitic stainless steel for freedom

from rust.

Differential angle at face between seal ring and

bonnet is maintained for good sealing tightness.

Hardness of seal ring is HB 90 (Max.).

Edge Preparation

Pressure Seal

BHEL standard valve body is designed in accordance

with ASME B 16.34.

BHEL standard inside diameter is decided based on

ASME B 16.34 or connecting pipe size.

Edge preparation is in accordance with ASME B

16.25.

Sealing surface on both body and bonnet is overlaid with austenitic stainless steel for freedom from rust.

Differential angle at face between seal ring and bonnet

is maintained for good sealing tightness. Hardness of

seal ring is HB 90(Max.).

Opening Angle

Pressure seal for spindle

Arm-disc Connection

Spindle

Opening angle of 45-50 degrees is provided for

quick closing due to reverse flow and for a lower

pressure drop when fully opened.

Sealing mechanism through spindle is of the same

construction as the one of pressure seal bonnet.

To ensure secure connection between arm and disc

nut, welding to disc instead of split pin is used.

A special material named OHTARON with hard

Chrome plating is used in all valves.

Cushion plate

Stopper pin

Bushing

OPTIONAL FEATURE

To achieve a shock absorbing effect and to reduce

fluttering action, cushion plate is provided.

To prevent the disc from revolving, stopper pin is

inserted between disc and arm.

Special material named SUPER NICKERON is used

to prevent wearing and /or seizure.
