Self acting, Pilot & Piston operated pressure reducing valves are most popular for pressure reduction of steam in all types of industries. The valve operates on Spring Balance principal. The downstream pressure is sensed below the diaphragm which is balanced by the spring tension. Increasing spring tension, increases outlet pressure and vice versa.

The valve has additional external sense line provision also, which improves performance and accuracy of outlet pressure, irrespective of changes in upstream pressure. The valve has high turn down ratio, from full to 10%. It is most ideal for low and medium pressures.

Dalring Muesco make pressure reducing station, duly IBR approved is designed, sized and manufactured to the exacting requirement of customers based on parameters like flow Rate, pressure, temperature, etc. PRV is of self regulating type Model PRV 1001, generally for low-pressure duty. Recommended PRV for high-pressure duty and higher turn down ratio (up to 40:1) is Robotrol operated Control Valve – Model RB 70142.

Safety requirements such as safety shut-off valve with over pressure and under pressure setting, diaphragm operated relief valve, flame arrestor etc. can be incorporated as required. Active and monitor regulators with by-pass line is also possible. The unit gives excellent down-stream control of pressure with full safety.

Darling Muesco make pressure regulating valves are self actuated – spring & diaphragm operated for precise control of pressure for maximum combustion efficiency in commercial installation.These valves has very high flow capacity and very high precise regulation with the help of Pilot.

These valves (also referred as Pressure Regulators) maintain the outlet pressure steadily irrespective of varying inlet pressure in the pipeline. These high capacity regulators are used as final control elements for burner application, installed just ahead of burner manifold in industrial furnaces. These high capacity regulators are used for air, nitrogen, natural gas, hydrogen and many other industrial gases. The regulators give very precise downstream pressure and very low fluctuations.

The Pilot Operated Regulators gives very precise downstream pressure and very low fluctuations, with precision up to 1/10th of the inlet pressure. They are extensively used as active and monitor control in series for natural gas pressure reducing system.

Darling Muesco make of Deluge Valve is an automatic control valve, which is pneumatically or electrically actuated, with size ranging from 2” to 20”. The valves are TAC approved and manufactured conforming to UL specifications. The valves are compatible to all types of fire detection system.

Our Deluge Valves are fully automatic, as they are of flow operated type. The valve opens on demand to provide water flow to the fire protection sprinkler systems. Pilot systems can be hydraulically, pneumatically or manually operated. Opening of the valve is by electrical signal to solenoid valve loss of control pressure or by manual opening. The trim is factory assembled, thus avoiding piping work at site. This reduces problems during commissioning and after sales services.

The valve type is diaphragm which has following features:-
• Very fast response
• Low friction
• High flow capacity
• Minimum maintenance
• Imported diaphragm
• Patented quad seal ring for zero leakage.

It also has manual station as test trim, manual override and drain line. The operation of our valves is much simpler as compared to other brands. Also, the response time of our valve is just 2-3 seconds or even less, as against 10-20 seconds as in case of other brands. The installation of our valves, being globe type, is much faster and economical.

Darling Muesco make of various designs and types of De-Super heaters are offered for different requirements to reduce steam temperature from super heated to saturated:-

• Variable Spray De-Super Heater VSD-110.
• De-Super Heater Mechanically Atomised-DMA.
• Ventury Type De-Super Heater V-105.

Based on process parameters, suitable De-Super Heater is offered with complete instrumentation package.
