Temperature regulating valve Type ORV

Assures optimal oil temperature control in refrigeration systems

ORV are 3-way industrial valves for maintaining a constant oil temperature in gas compressor systems, by mixing hot and cold oil in the lubricating system of e.g. screw or turbo type compressors.

The ORV valves are with few components and with extended cylindrical connections, to ensure ease of installation and service.

Features

• Stainless steel nickel plated thermostatic element.

• Butt-weld (DIN, ANSI) or socket weld (SOC) connection.

• No manual adjustment.

• Plug and Play design.

• Optimised ow characteristics.

• Robust design.

• High resistance against vibrations or shock.

• Can be mounted in any direction.

• Easy to dismantle and service when required.

• Classication: DNV, CRN, BV, EAC etc. To get an updated list of certication on the products please contact your local Danfoss Sales Company.

Temperature regulating valve, type ORV

Functions

Mixing operation

ORV valve can work as a mixing or diverting valve. The ORV temperature regulating valve utilises high coecient of thermal expansion of wax to create the internal movement necessary to have a cold and a hot inlet mixing to a common outlet. The outlet temperature corresponds to the nominal temperature of the thermostatic element.

The valve house has three ports:

• Port A is used for the common outlet

• Port B is for the hot inlet

• Port C is for the cold inlet

When the compressor unit is cold at start up, the thermostatic element will be contracted to let the full ow from port B pass until the nominal temperature (-12 °C / 10°F) is reached (Figure 1: Valve house(g. 1.1)). The thermostatic element will then begin to extract to let the outlet become a mixture of hot and cold oil.

When the nominal temperature is reached, the element is positioned in approximately half open position (Figure 1:

Valve house(g. 1.2)). If the temperature is reaching approximately the nominal temperature plus 5 °C / 9 °F, the

thermostatic element has been extracted to its fully open position (Figure 1: Valve house(g. 1.3)). In this position the oil temperature will only come from the cold inlet port (C) from oil cooler.

Figure 1: Valve house

From Figure 1: Valve house, it can be seen how the sleeve on the element is sliding in a vertical direction. The thermostatic element is kept in position by a spring.

Diverting operation

Diverting operation is similar to the mixing operation. It is carried out with separation in to two of the uid with single temperature. Due to that the temperature on the inlet is very stable fact the regulation is very smooth. The inlet temperature would correspond to the nominal temperature of the thermostatic element.

The valve house has three ports:

• Port A is used for the common inlet

• Port B is for the cold outlet

• Port C is for the warm outlet

The diverting operation otherwise is similar to the mixing operation.

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

The upper left curve shows the viscosity of dierent grades of oil as a function of the temperature. The viscosity is continued into the upper right curve where the 17 m3/h must be found. The line is drawn vertically downwards into the capacity table for the ORV valve models.

As shown two selections can be made: Either ORV 40 H2 with pressure drop at approx. 0.56 bar or ORV 50 H2 with pressure drop at 0.42 bar.

The nal selection will depend on the available pressures in the system. If the pressures are low (or can be low at certain loads) the ORV 50 H2 might be preferred. If the pressures are constantly available the pipe dimension may be taken into account and the ORV 40 H2 might be preferred.
