Slow-closing check valve also known as butterfly cushion check valve, oblique bridge soft seal slow close check valve seat adopt bevel type, large eccentric design, external or built-in buffer system, is my company independent research and development,with independent intellectual property rights of patented products.

Mainly installed in the pump export and medium deep place,prevent the backflow medium, automatic eliminate the destructive water hammer,protect the safety of water pump and pipeline. It is mainly composed of valve body, valve plate,buffer system. Structure is novel, the closing of the valve plate short journeys, smooth operation, low energy consumption in medium under the action of buoyancy open closed,is a new generation of energy saving and consumption reducing and environmental protection products.

What are the characteristics and biggest advantages of Slow-closing check valve?

①Easy to open
Adopt bevel type seat, easy to open, open valve in low velocity of fluid mechanics;

②Close short journeys, low energy consumption
Close short journeys, required to reduce energy consumption, reducing the media on the impact of the valve and valve seat and the water hammer wave in pipe;

③Multiple cushioning devices
According to the working conditions of the scene, there are built-in and built-out buffer device to choose from;

④Small flow resistance, smooth operation,low noise
Novel and reasonable structure of the valve. Body with to prevent excessive open the limit of structure, the valve plate adopts the whole suspension stream line structure rigidity, small flow resistance, smooth operation,low noise;

⑤The valve open intuitive visual
With the opening indicating device, the valve open intuitive visual;

⑥More longer service life
Seat USES the taper sealing,reliable sealing, long service life;

⑦According to the condition and medium hard seal soft seal(H)(x) to choose from.
According to the condition and medium hard seal soft seal(H)(x) to choose from. Generally choose sot seal, zero leakage, buffer voice closed small; But medium for sewage or containing particles, and the solid impurities such as sand, advised to choose a hard seal, improve the service life of the valve;

⑧More reliable structure
Adopting direct stroke cylinder cylinder replacement back transformation,more reliable structure, ensure the operation of the valve more easy smooth, no resistance;

⑨Easy to install and maintain
With a standard interface of buffer device, and strictly to ensure interchangeability so in
production, installation, maintenance, replacement, transportation process, is more convenient.

Application conditions of slow-closing check valve

The slow-closing check valve is an advanced, intelligent hydraulic valve that is being used more
and more widely in various industries. The main applications are in the following areas:

1. Wastewater treatment: Slow-closing check valves can be used in water treatment systems to
prevent wastewater backflow and back-tide, ensuring a complete and flawless water treatment
system.

2. Fire fighting systems: In fire fighting systems, slow closing check valves prevent sewage or fire
fighting foam from flowing back from the fire fighting pipes to the fire fighting tank or city water
network.

3. Industrial applications: Slow-closing check valves can be used in a variety of industrial piping
systems such as petrochemical, pharmaceutical, and energy to protect equipment and pipelines
from high pressure and contamination.

4. Automation: Slow-closing check valves are used in automation equipment to control fluid flow
and to avoid damage caused by fluid backflow.

5. Construction: In construction, slow-closing check valves can be connected to cast steel, cast
iron, and organic pipework to maintain the flow of water and avoid pipework hazards.
