The check valve is an automatic opening and closing valve that does not require manual operation or other actions. It relies on the flow of the pipeline medium itself to open or close the valve. It is mainly used to prevent the reverse flow control of the pipeline medium. It is also called a check valve. or reverse flow valve. The check valve has only one flow direction, that is, it can only flow along the water inlet and cannot go backwards. When the medium flows backward, the valve disc is closed. Check valves are generally installed in places to prevent the backflow of media when the valve is not closed. For example, a check valve is installed at the outlet of a common water pump to prevent high-pressure water from flowing backward into the water pump, causing the water pump impeller or other components to become loose or damaged due to hydraulic impact, leading to accidents. In short, check valves are used in pipelines or equipment to prevent the backflow of media. Common check valve types include: double-disc swing check valve, rubber disc check valve, ball check valve, etc. Our factory can produce all of them. We have more than 20 years of production experience and follow American standards ANSI and German standards. Designed, manufactured and inspected to DIN, British BS, GB and other advanced industrial national standards, you are welcome to purchase.

Y strainer (water filter) belongs to the pipeline coarse filter series and can also be used for gas or other  large particle filtering, installed on the pipeline can remove larger solid impurities in the fluid.

Enable machinery and equipment (including compressors, pumps, etc.) and instruments to work and operate normally and achieve stability process to ensure safe production.

Y-type filter (water filter) can be customized according to customer’s requirement (special pressure, special caliber).  It has the advantages of production simply, easy installation and cleaning, and Large amount of contamination.Y-type filter is an indispensable filter device in the pipeline system of conveying media. Y-type filter is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed level valve or other equipment to remove impurities in the media to protect the normal use of valves and equipment. Y-type filter has the characteristics of advanced structure, low resistance, convenient blowdown and so on. Y-type filter applicable media can be water, oil, gas.

The valve consists of a main valve and an external control pilot valve. Mainly installed in the bypass of building protected water supply system , to guarantee the pressure in the water supply area upstream of the main valve . When the pressure in the water supply pipe exceeds the set pressure of the pressure relief valve, the pressure relief valve is opened to prevent the pipeline and equipment from being damaged due to over pressure. The valve is mainly used for pressure relief of the circulating system of high-rise building fire test.

It is the upgrade product for spring type safety valve.

It is used for emergency repair of sand holes, cracks and fractures in the straight pipe parts of pipelines.

The shell adopts the card groove design around the shell, and the pressure is twice that of other similar  products.

The rubber ring is embedded in the shell to reduce the amount of glue to avoid secondary pollution to the water quality.

On the basis of the original nail tube, the removal device is added to increase the pressure bearing capacity of the product and avoid the pipe falling off.

From the rubber ring, does not affect the sealing effect. The rubber ring adopts the thickened double groove design to increase the compensation amount.

The anti-slip chuck adopts hinge design to make it fast to install and shorten the construction time.

Butterfly valve is a simple structure of the control valve, can be used for the switch control of low-pressure pipeline media butterfly valve refers to the closing part (valve disc or butterfly plate) for the disc, revolving around the valve shaft to achieve the opening and closing of a valve. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.

Air valves are used in pipeline exhaust, often installed at commanding heights or elbows, etc., to eliminate excess gas in the pipeline, improve the efficiency of pipeline road use and reduce energy consumption.
