Valves and Controls

OVERFLOW VALVE


OVERFLOW VALVE

  • Three functions in one valve.

  • The OFV valve combines the functions of an overflow valve, a check valve and a stop valve COFV are angle-way over flow valves, which have adjustable opening pressure and cover the differential pressure range 2 - 8 bar (29 -116 psi).

  • The valve can be closed manually, during plant service and have back seating, enabling the spindle seal to be replaced with the valve still under pressure.

  • The valves are especially designed to prevent fluttering due to low velocity.

  • In consequence it is possible to apply the valves with wide fluctuations in capacity demands and maximum performance to part load.

  • A flexible O-ring provides perfect sealing over the seat

OVERFLOW VALVE

Range Temperature range: –46°C to +150°C
Pressure range : The valve are designed for max. working pressure 40 bar g (580 psig)
Installation The valve is designed to resist very high internal pressure, but as to the pipe system in general, hydraulic pressure caused by thermal expansions in entrapped refrigerants should be avoided.
Application Applicable to HCFC, HFC, R717(Ammonia) and R744 (CO2).
