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.

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.
