Cast iron check valve PN 16

Description

Cast iron check valve PN 16

One of the components of water transfer is Cast iron check valve PN 16 . As its name suggests, its function is to straighten the flow of water, that is, when the flow is in one direction, this valve is open, and when the flow is reversed, the valve is closed and stops the flow.

These valves are usually placed after the pump to prevent water from entering when the pump is stopped, which causes the wear of the pump. Another use is to prevent water hammer and the resulting damages. As we know When the pump stops moving suddenly, like a power outage, it causes a ram shock.

The material of this product is made of cast iron and it is produced in two pressure ranges of 10 atmospheres and 16 atmospheres, and it can be used for all liquids, especially in petrochemical and power plants, and they can withstand all high temperatures easily. It is placed in the network.

Disadvantages

Due to the cast iron material, this product has a heavy weight and it is difficult to transport it in the garage.

Cast iron fittings are produced in different sizes from 50 mm to 400 mm and to wings, these fittings increase the costs of transmission projects.

Cast iron joints break quickly in front of sudden impacts. Care should be taken during transportation

Advantages

One of the advantages of cast iron fittings is 1- its resistance to corrosion

2-Resistance to high temperatures

3- Resistance to high pressures as well as negative pressures

4- Resistance to abrasion

5- Resistance to external pressures such as

Weather changes, which is the reason for the expansion and contraction of the connection and causes the failure of the connections
