Pressure Reducing/ Regulating Valve

• Nitrogen Blanketing Valve:

Gas Pressure Regulator/Low Pressure Reducing Valves.
Models: – DP 266HP/BP/LP
Function: – These DP 266HP are self actuated, either spring or Diaphragm operated for accurate control of gas pressure for maximum combustion efficiency in commercial gas installations. The regulator maintains the outlet pressure, irrespective of fluctuation in inlet pressure in the pipeline.
Application: – These high capacity regulators are used in Air, Nitrogen, Natural Gas, Hydrogen etc. industrial gases.
Size: – 15 NB – 150 NB
Pressure Rating: – 150# & 300#
Max. Inlet Pressure: – 20 Kg/Cm2
Max. Outlet Pressure: – 50mm WC.
Material of Construction: – Carbon Steel, Stainless Steel, Duplex Steel, etc..

• Pressure Reducing Valve DA 3550 & 355:

Automatically reduces a higher inlet pressure to a constant lower outlet pressure. The valve consists of a main valve and (Fig. 55) pressure reducing control pilot. Slight changes in downstream pressure acts on topside of control diaphragm causing main Valve to counteract pressure changes and hold a constant outlet pressure.

The regulator will reduce the upstream pressure to a constant downstream pressure regardless of the change in flow rates/or inlet pressure. The pilot is a Normally Open

valve that senses the downstream pressure.

Models: – DA 355 (Globe), DA 3550 (Angle).

Size: – 25 NB – 750 NB.

Spring Range: – Standard: 20-175 Psig, Optional: 5-35 Psig.

Materials: – Carbon Steel, Alloy Steel, Stainless Steel etc.

Additional Features: –

Pressure Reducing/Sustaining.

Pressure Reducing/Check

Pressure Reducing/Solenoid On-Off.

Pressure Reducing/Surge

Pressure Reducing/Low Flow By-Pass.

• Pilot Operated Pressure Reducing Valve For Gas & Air DP 876:

Function: – Series DP 876 are pilot operated used for Air & Gas services, In single stage, pressure reduction can be achieved very precisely upto 1/10 of the inlet pressure. Pilot operation with pressure downstream pressure & with very minimum errors & fluctuation.
Size: – 50 NB – 200 NB
Pressure Class: – 150# & 300#.
Material: – Carbon Steel, Stainless Steel, Duplex Steel, Super Duplex Steel. etc..
Application: – Used in Natural Gas Pressure reducing stations, where inlet pressure is very high, but requires precise downstream pressure.

• Pressure Reducing Valve – Steam Services DPRV 5004:

DEVaaM make Self acting, pilot & piston operated pressure reducing valves are most popular for reduction of steam in all types of industries. The principle on which this valve operates is Spring Balanced.
The downstream pressure is sensed below stainless steel diaphragm which is balanced by spring tension. Increasing spring tension increases the outlet pressure & vice versa. The DEVaaM make pressure reducing valve has external sense line provision, which improves performance & accuracy of outlet pressure.

Size: – 15NB – 200NB.
Pressure Rating: – Class 150 & 300 as per Table H BS10.
Outlet Pressure: – 0.5 Kg/Cm2 – 12.5 Kg/Cm2.
End Connection: – Flanged & Screwed.
Materials: – Carbon Steel, Stainless Steel, Duplex Steel, Super Duplex Steel. etc..
