Non Slam Axial Check Valve Manufacturer in China

At present, the axial flow check valves on the market are mainly monopolized by several major brands in Europe and the United States. After years of R&D and practice, THINKTANK has accumulated in the design, manufacture, inspection, and experiment of axial flow check valves. The mature experience has successfully replaced European and American brands, saving huge costs for owners, contractors and engineering companies, and the fast delivery date has greatly shortened the project delivery time.

Design and Selection of Check Valves

Check Valve Types

ball check valve installation1 (1)

Ball Check Valve (Lift)

The ball check valve is simple and compact and commonly used on small water or wastewater pumps where the economy is important. A ball check valve consists of a threaded or flanged body with internal features that guide a rubber‐coated ball in and out of the seat as the flow goes forward and reverse.

silent check valve

Silent Check Valve (Lift)

The silent check valve is suitable for water supply and drainage pipelines. The valve disc is guided by the central axis at both ends of the inlet and outlet, and it can be opened and closed flexibly. It can be installed horizontally or vertically. The valve disc is spring-loaded, and its quick closing can effectively reduce the water hammer pressure, with good sealing performance and no noise when closing. It has the advantages of small size, lightweight, low fluid resistance, fatigue resistance, and long service life.

静音式止回阀 (1)

Nozzle Check Valve (Lift)

The axial flow check valve is a high-performance check valve designed in accordance with API 6D and ASME B16.34. In addition to the function of a general check valve, it also uses superb sealing technology to make the valve zero leakage. Unique Venturi inner streamlined flow channel design has the advantages of small flow resistance, good flow state, fast response to medium pressure changes, and small size. It is the preferred valve for general industrial use and pipeline use and is especially suitable for oil pump outlets and natural gas compressor outlets.

dual plate check valve (1)

Dual Plate Check Valve (Swing)

The dual plate check valve has two spring-loaded butterfly valve disc, which are assemble on the shaft of the disc through hole. Compared with the single disc swing check valve of the same size, this structure also reduces the disc weight by 50%. Due to the spring load, this valve responds quickly to reverse flow.

斜盘止回阀 (1)

Traditional Swing Check Valve with Lever and Weight

The heavy hammer check valve is mainly used in the water supply system. It is installed vertically in the pipeline. It depends on the pressure difference in the system and the weight of the valve flap to realize the lifting, automatically preventing the backflow of medium water and ensuring the normal operation of the pipeline.

斜盘止回阀3 (2)

Tilted Disc Check Valve

The seat sealing surface of the tilting disc check valve is a part of the oblique cone. The sealing line formed between the seat and the disc is an approximately elliptical curve. The angle between the plane of the curve and the centerline of the valve flow path is 60 degrees; The long axis center of the approximate elliptical sealing line forms an angular eccentricity with the cone axis, that is, the second eccentric included angle between the axis of the cone where the valve seat sealing surface is and the centerline of the valve body flow channel is 15 degrees to 20 degrees

Basic Knowledge

Here is some basic knowledge about the check valve, if you have other questions, just feel free to contact us. 

What is no slam axial nozzle check valve?

Nozzle Check valves which are also called an axial flow check valve, which is very important for non-return fluid purpose with no slam and fast closing characteristics. Mostly axial check valve installed downstream of rotating equipment to protect the expensive mechanical equipment from possible damages due to backflow.

How does an axial flow valve work?

The Axial check valve is normally closed. When closed, the closing forces are control chamber pressure acting on the sleeve exterior plus the elastic preload. The opening forces are inlet pressure acting on the interior of the sleeve through the inlet cage.

The most common 6 types of check valves

Nozzle Check Valve, Silent Check Valve, Silent Check Valve, Dual Disc/Plate Check Valve, Swing Check Valve, Tilted Disc Check Valve
