Forged Check Valve
For medium and low pressure check valves with DN50mm or less, the body and bonnet should be bolted, that is, a Bolted Cover Forged Check Valve should be used.
For high-pressure forged steel check valves under DN50mm, the pressure self-sealing type (Pressure Sealed Bonnet Forged Check Valves) should be selected.
For medium and high pressure forged steel check valves with DN50mm or less, Welded Cover Forged Check Valves should be used.
