ROV 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 turbotype compressors.The ROV valves are with few components and with extended eylindrical connections, to ensure ease of installation and service. ROV valve can work as a mixing or diverting valve. The ROV temperature regulating valve utilises the high coefficient 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 will correspond 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
Two types of thermostatic elements 49°C and 60°C. Thermostatic elements are made of stainless steel. Easy to maintain and does not require manual adjustment. High resistance to vibration or shock. Can be installed in any position. Valves are available with butt-welded type connections.
