 On the contrary, the valve is closed when the medium flows back.  Swing check valves have a disc that is tilted and rotates on its axis and work in a similar way to lift check valves.  Check valves are often used as bottom valves in pumping units to prevent the backflow of water.  Check valves are combined with globe valves to provide safety isolation.

Check valve is a valve that relies on the medium itself to flow and automatically open and close the valve flap, used to prevent the backflow of the medium, also known as check valve, check valve, backflow valve, and back pressure valve.
Check valve is a valve installed in the pipeline to prevent the backflow of media. Check valves can be used on many types of pipelines such as over water, oil and gas, etc.
The Chinese Refrigation Equipment Exhibition is the most special exhibition in Refrigation field.Our Diefei Brand Check valve and Butterfly valve is an important part of this Exhibition.We have the expertise and experience to produce,also have a big After-service team . We get the high apprecition from our customers.
The purpose of using check valve is to avoid the backflow of medium, generally in the outlet of the pump should be installed check valve. In addition, the outlet of the compressor should also be installed check valve. In summary, in order to avoid the backflow of the medium, in the equipment, installation or pipeline should be installed check valve in general in the nominal diameter of 50mm of the horizontal pipeline are selected vertical lift check valve. Straight lift check valve in the horizontal pipeline and straight pipeline can be installed.
Check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.
The check valve opening and closing parts are opened or closed by themselves by the flow and force of the medium to prevent the backflow of the medium. The valve is called a check valve. The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents. The check valve, also known as a one-way valve or a check valve, is used to prevent the backflow of the medium in the pipeline.
Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.Advantages of the gate valve.1. low fluid resistanceBecause the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.2.
Entering 2022, our orders for butterfly valves and check valves are increasingly full, and the delivery date has been scheduled to April. We will continue to maintain a booming production and sales situation, and will not be affected by the Spring Festival holiday at all. The delivery date will start in late February.In addition, in a new field, the photovoltaic new energy business sector, our company continued to win the bid for the supporting projects for the newly expanded production base of JA Technology and LONGi Group.
In production and life, the emergence of valves is that the utilization rate of their valves and accessories is getting higher and higher, such as check valves, check valves, electric butterfly valves, pneumatic butterfly valves, rubber soft joints, electric ball valves, one-way valves, and wafer butterfly valves. , filter, etc., which have brought great convenience to production and life.
Test valve refers to the hole and remaining elements of the circular disc and with the aid of its own weight and media stress generated motion to block the media float lower back valve.  automatic valve elegance, additionally referred to as test valve, one-way valve, backflow valve or isolation valve.  disc movement is split into lifting and swing.  elevate test valves are comparable in creation to globe valves besides for the stem that drives the disc.  the medium flows in from the inlet quit (decrease side) and flows out from the hole give up (higher aspect).  valve
