Specifications* Pressure Ratings : Class:150-300 #* Temperature Ranges : -40 to 90 deg. C.* Standard Materials : Stainless Steel* 150-400 mm ASTMA 216 Gr. WCB & Alloy Steel

The DLR-44 Nutech-01 series regulator is a piston sensed, dome loaded, positive biased, pressure regulator. The positive bias provide a constant outlet pressure from 50-1500 PSI (3.4-105 BAR) greater than the reference pressure.

* spring loaded safety relief valve* full lift pop type design* open bonnet with cap & liver* close bonnet with liver* close bonnet with packed liver.

Over pressurization protection : protect the downstream piping system and the regulator's low pressure chambers against over pressurization due to possible regulator malfunction or failure to achieve complete lockup.

The 900 series altitude valves controls the liquids automatically in terms of their level in the reservoirs without any additional arrangements like float or other controlling devices. Function: It automatically controls the liquid levels in the reservoir. The design is compact and easily mounted on the equipment and has free maintenance characteristics. 900 Series valves are hydraulically operated, diaphragm actuated, pilot controlled globe type valves.

Loading pressure - either air or inert gas - is applied to tge tope of the diaphragm by the loader to open the main valve against the valves spring and inlet pressure. After the valve is open, more loading pressure is applied to the top of the diaphragm to keep the valve open while building up the desired reduced pressure under the diaphragm and to restore equilibrium under flow conditions. Reduced pressure from the down stream piping system is applied to the bottom of the metal diaphragm through an external impulse line.

Over pressurization protection : Protect the downstream piping system and the regulator's low pressure chambers against over pressurization due to possible regulator malfunction or failure to achieve complete lockup. The allowable outlet pressure is the lowest codes, state codes, Nu-Tech bulletin NEV-300 or other applicable standard. The method of protection can be relief valve, monitor regulator, shutoff device or similar mechanism.
