OFB
OFB shut off ball valves are a suction solution for superior reliability of oil-free system featuring Danfoss Turbocor® compressors.
OFB shut off ball valves efficiently prevent from refrigerant migration during extended standby periods and therefore, from the risk of liquid slug upon compressor restart.
Features and benefits
- High reliability through the stem and seat designed for high cycles
- Strong reliable sealing
- Tight shut off ball valve
- Low torque enabling long lifetime of both valve and actuator
- Easy integration and installation through the modular flange system compatible with different piping standards. Inlet flange size 4" or 5" fitted for different Turbocor® compressors
- Welding and brazing interface to standard pipes and elbows
- Ready to equip with Actuator - ISO 5211 -F07/17 mm. Actuator can be mounted to make the OFB to be controlled electrically
- High system efficiency through the smooth intake flow with low pressure difference and low flow turbulence
- Effective design is direct mounting to the compressor
- Low torque - a quarter turn actuator rated at 80 Nm can be sufficient and lead to a long lifetime
