CAST IRON SWING CHECK VALVE PN16
CHV401-PN16
Product Description
CAST IRON SWING CHECK VALVE PN16 is a cast iron swing check valve designed for PN16 (16 bar standard pressure).
Advantage:
High strength: Cast iron material has high mechanical strength and can withstand the working environment under PN16 standard pressure.
Effectively prevent backflow: The swing-type design can effectively prevent medium backflow and ensure the normal operation of the pipeline system.
Strong durability: Cast iron material has good corrosion resistance and wear resistance, which can ensure long-term reliable operation of the valve.
Usage: CAST IRON SWING CHECK VALVE PN16 is usually used in medium-pressure industrial pipeline systems as a control valve to prevent medium backflow, such as water supply systems, sewage treatment systems, air conditioning and refrigeration systems, etc. This kind of valve can ensure that the fluid flows unobstructed in the normal direction, and can be closed in time when the fluid flows in the reverse direction, protecting the pipeline system from damage.
Features
Product Overview
Cast iron material: The valve body and valve cover are made of cast iron, which is corrosion-resistant and pressure-resistant.
Swing-type design: The swing-type disc design ensures that the valve opens when the fluid flows in one direction and closes when the fluid flows in the reverse direction.
PN16 standard pressure: The design pressure is PN16, suitable for medium pressure pipeline systems.
