Swing Check Valve Flange Connection EN1092 PN16 PN10 Rubber Seated Non-return Check Valve
Rubber swing check valves mainly used for the outlet of the pipeline in the industrial departments such as water supply and drainage system, petroleum and chemical inoustry, so as to prevent the media from coun-tercurrent. Because the sealing ring of the product isdesigned byinclined design, the closing time is short, and the water haammer pressure can be reduced. The disc is made of butadiene rubber and steel plate pressed by high temperature. lt has good scouring resistance, good sealing performance, simple product structure, convenient main-tenance and transportation.

Air Release Valve Ductile Iron Composite High Speed Vent Valve Flanged Connection
Air release valves are critical components in pipelines and systems used to transport fluids such as water, oil and natural gas. These valves are designed to remove air or accumulated gas from the system, preventing air from causing flow interruptions and inefficiencies.
The presence of air in ducts can cause a range of problems, including reduced flow, increased energy consumption, and even damage to the system. This is why exhaust valves are vital, as they help maintain optimal performance of your system and ensure smooth operation.
One of the primary functions of a vent valve is to release trapped air from the system. When fluid enters pipes, air can become trapped in higher places, such as bends, heights, and mountaintops. As fluid flows through pipes, air can accumulate and form air pockets, resulting in reduced efficiency and increased pressure. Bleed valves are strategically placed at these high points to release trapped air and restore system balance.
Another important function of the exhaust valve is to prevent vacuum conditions from forming in the system. A vacuum condition may occur when the fluid velocity changes suddenly or when the liquid column breaks due to a high point or sudden valve closing. These vacuum conditions can cause equipment damage, pipe collapse, or even implosion. Vent valves protect the system by allowing air to enter and equalize pressure, preventing vacuum conditions from forming.
In summary, vent valves play a vital role in maintaining the efficiency and smooth operation of pipes and systems that carry fluids. They release trapped air and prevent vacuum conditions, ensuring optimal operation of the system and preventing interruptions and damage. By understanding the importance of vent valves and taking appropriate installation and maintenance measures, system operators can ensure the longevity and reliability of their piping and systems.

Good Selling Composite High Speed Vent Valve PN16 Ductile Iron Flanged Connection Air Release Valve
Composite high speed air release valve is composed of two parts: The high pressure diaphragm automatic air release valve and the low pressure intake air release valve. The high pressure air valve releases a small amount of air accumulated inside the pipe under pressure. Low pressure air valve can discharge the air in the pipe when the empty pipe is filled with water, and automatically open and air inlet into pipe to eliminate vacuum when the pipe is drained or vacuum or under the condition of water column separation.
