Advantages of China Valve Manufacturing Co., Ltd. Check Valves
Preventing Backflow
SUNFOR ® Fire check valves are designed to prevent backflow, which is the reversal of the flow of water or other fire suppressant agents in a fire protection system. Backflow can cause contamination of the water supply and reduce the effectiveness of fire protection systems. Fire check valves stop backflow by automatically closing when there is a sudden drop in pressure.
Saving Lives and Property
The use of SUNFOR ® check valves in fire protection systems is critical in saving lives and property. Fire check valves help to confine fire to a specific area by closing off the flow of flammable liquids or gases. This helps to prevent the spread of fire and limit the damage caused by the fire. In addition, the use of fire check valves reduces the need for human intervention in emergency situations.
Durability
SUNFOR ® check valves are made of durable and corrosion-resistant ductile iron premium material. They are designed to withstand extreme temperature and pressure changes, ensuring long-lasting performance.

Check Valve Application

Check Valve For Fire Protection System
Fire check valves play an essential role in ensuring the safety of buildings and the people who occupy them. They are an important component of fire protection systems and are designed to prevent the backflow of water in the event of a fire.
During a fire, water is pumped into the building through fire sprinkler systems and other fire protection equipment. Without proper backflow prevention, however, this water can flow back through the pipes and contaminate the water supply, potentially causing damage to the building and endangering those inside.
Fire check valves prevent this by automatically closing when the water pressure in the pipes drops, preventing any backflow from occurring. They are typically installed at the base of the riser, which is the vertical section of the pipe that feeds the water to the fire sprinklers and other equipment.
check valve for residential and commercial plumbing systems
As we all know, a plumbing system is an integral part of any building, be it residential or commercial. And when it comes to the safety of such plumbing systems, fire check valves play a vital role. These valves are designed to control and prevent the spread of fire in a building through the plumbing system.
A fire check valve is a type of valve that allows water to flow in only one direction. The valve opens in the event of water flowing in the direction of its arrow, but it closes automatically when backflow or siphoning occurs. This ensures that contaminated water or other substances do not contaminate the potable water supply.
In case of a fire outbreak, fire check valves play a critical role in preventing the spread of fire through the plumbing system. This is because the valves are designed to automatically close when they detect an increase in temperature caused by heat from the fire. The closure of the valve prevents the spread of water through the system, thereby preventing the spread of the fire.


Check valve For industrial applications
A fire check valve is an essential component in industrial applications where safety is of utmost importance. This valve ensures that fire does not spread through a piping system in case of an outbreak. It helps to control the flow of water and extinguish the fire, thereby minimizing the damage caused.
The fire check valve is specifically designed to prevent backflow, ensuring that the water supply is always flowing in one direction. This ensures that the water supply is not contaminated and remains potent enough to extinguish the fire.
In industrial applications, fire check valves are installed in fire protection systems, and they are often required by law. They play a crucial role in protecting human lives and property in case of a fire outbreak.
