Product description

Effectively preventing medium from backflow, the lift check valve is suitable for the application on the pipeline of petroleum industry, chemical industry, hydraulic power plant to control water, gas, oil and other corrosive medium. Using under high pressure is also available with this valve.
Features
1.The valve disc moves up and down along the midline of the valve body. Under the pressure of the fluid which flows in one direction, the valve disc will be raised up from the sealing surface of the valve seat. If there is backflow, the valve disc will return back to the valve seat to cut off the medium.
2.To further reduce the impact, the lift check valve is engineered with piston dashpot, which is installed with spring.
3.There are small holes on the piston. When the piston is moving, the medium will flow slowly, which will reduce the impacting force to the valve greatly .

Company introduction

Covering about 43,920 square meters in area, Henan Quanshun Flow Control Science & Technology Co.,Ltd is a special high-tech enterprise engaged in manufacturing flow control equipment including: semi-ball valve ,rotating ball valve ,ball valve, control valve, butterfly valve, gate valve, check valve and others. Our equipment can be used in poor working condition with strict requirement on corrosion resistance, abrasion resistance and erosion resistance of the product.
Currently the registered capital of our company is more that 8 million Dollars .We have set foot in the valve industry from the year 1984. In the past 30 years we have obtained rich experience in industrial valve and project service.
Due to the all-round quality management system,our valves has successfully passed certain certificate like :ISO9001, ISO14001,OHSAS18001,CE and some others.At present we granted 31 national patents.The superior quality of our valves come from strict quality control,reasonable inspection process and sufficient attention on each detail.
Possessing strong technical strength, our factory is equipped with advanced machining and testing equipment,including machining center,numerical control machine tool,large-scale vertical lathe,large boring mill,grinding machine, multi-function valve performance testing device and so on.Therefore, we are capable of producing valves made of both general material and special materials like WCB,WC6,WC9,304,316,316L,CF8,CF8M, etc.
To complete the standard system of industrial manufacture, we make optimal overall arrangement on the production line. By utilizing the existed advanced equipment, we comprehensively control the casting process ,inspection process,machining,assembling and commissioning of the valve .
Highly praised in the industry due to the outstanding product performance,our industrial valves is applied in the fields such as mining industry , chemical industry ,metallurgy industry, water industry , power industry, nonferrous metal, and some others.
QUANSHUN FLOW CONTROL has successfully established cooperative relationship with final user such as CHALCO,V-COALIMEX ,SINOPEC group and other distributors , Engineer company & Designing institute from all over the world .
We are looking forward to building partnership with more customer from all over the world !
