| DH /- Series (Low Pressure Blanketing Regulator System ) |
 |
|
These type of self actuated downstream pressure control valves are used for high pressure range. These valves have handled pressure as high as 210 kg./sq.cm.g.
These valves are immune to drastic changes in the inlet pressure as long as inlet pressure is higher than the set point .The controlled downstream pressure remains constant irrespective of large changes in the flow through the valves because these valves have high flow capacity.
|
These are manufactured to meet with the individual demand of flow and the range of controlled pressure. The high pressure valve bodies are manufactured from bar stock to ensure the rigidity of the material. The material of construction is selected keeping in view, the service for which the valve is to be used. |

| Features |
Tight Shut Off Capability
Special trim design eliminates wear & erosion of seating providing excellent tight shut off capability over long working life.
Temper Resistant
An adjusting screw protective cap is standard to discourage tampering with pressure setting.
Wide range of Flow & Pressure Setting Capability
Wide range of body size available to satisfy varied flow requirements. Different set pressure ranges are available to cover set pressures from 0.5 Barg. To 9 Barg
