Application：

Ship pipeline system: Because ship valves need to bear complex pressure and bending loads, angle stop check valves are suitable for ship pipeline system to meet various fluid control requirements.

Maintenance suggestion:

• Regular inspection: check the sealing performance and operation flexibility of the valve regularly to ensure that the valve is in good working condition.

• Lubrication and maintenance: properly lubricate and maintain the valve to reduce friction and wear.

• Prevent blockage: regularly clean impurities and blockages in the valve to ensure smooth flow of fluid.

Material selection:

• Stainless steel: stainless steel materials such as 304, 316 and 316L have excellent corrosion resistance and high strength, and are especially suitable for corrosive media such as seawater.

• Cast iron: It has good castability and corrosion resistance, but its strength is low, so it is suitable for occasions with low pressure.

• Cast steel: it has high strength and corrosion resistance, can withstand high pressure and temperature, and is suitable for high pressure and high temperature systems.

• Brass: It has good corrosion resistance and sealing performance, and is often used for valve discs and seats.

• Rubber: In some types of marine stop check valves, it is used as a seal to improve the sealing performance of the valve.
