Nwụnye

  1. The POV valve is used in conjunction with the BSV back-pressure independent safety relief valve to protect compressors against excessive pressure.
  2. Install the valve with the spring housing upwards to avoid thermal and dynamic stress.
  3. Ensure the valve is protected from pressure transients like liquid hammer in the system.
  4. The valve should be installed with the flow towards the valve cone as indicated by the arrow on the valve.

ịgbado ọkụ

  1. Remove the top before welding to prevent damage to O-rings and teflon gaskets.
  2. Use materials and welding methods compatible with the valve housing material.
  3. Clean internally to remove welding debris before reassembly.
  4. Protect the valve from dirt and debris during welding.

Mgbakọ

  1. Wepu irighiri ihe ịgbado ọkụ na unyi sitere na ọkpọkọ na ozu valvụ tupu mgbakọ.
  2. Tighten the top with a torque wrench to the specified values.
  3. Ensure grease on bolts is intact before reassembling.

Agba na njirimara

  • Precise identification of the valve is made via the ID label on the top and stampna-abanye na valvụ ahụ.
  • Prevent external surface corrosion with a suitable protective coating after installation.

Nwụnye

  • Mara! Valve-type POV is categorised as a compressor overflow accessory (not as a safety accessory).
  • Hence, a safety valve (e.g. SFV) has to be installed to protect the system against excessive pressure.

  • The temperature in the area between the valve body and top, as well as in the area between the seat and the teflon cone during welding, does not exceed +150 °C/+302 °F.
  • This temperature depends on the welding method as well as on any cooling of the valve body during the welding itself (cooling can be ensured by, for example, wrapping a wet cloth around the valve body).
  • Make sure that no dirt, welding debris, etc, gets into the valve during the welding procedure.
