A check valve is a valve that allows fluid to flow in a fixed direction and automatically prevents it from flowing in the opposite direction (backflow), also known as a non-return valve. It is an auto

Check valve is a valve that opens when the pipeline system flows downstream and closes when the pipeline system flows upstream. It is mainly used to prevent the backflow of the medium, the reversal of

Ball valves are generally very durable and most of the time require little maintenance to keep them running smoothly for long periods of time. This is partly due to the simplicity of the ball valve

The ball valve evolved from the plug valve, and it has the same 90-degree rotation lifting action. The ball valve can be closed tightly with only a 90-degree rotation operation and a very small torque

A complete and independent Air Conditioning System can be basically divided into three parts, namely: cold and heat sources and air handling equipment, air and cold and hot water distribution system,

A thermostatic valve is a device that is used to control the temperature of a system by regulating the flow of a fluid. It is commonly used in heating and cooling systems, such as radiators or air con

Check valves are essential components in various industries, including plumbing, oil and gas, and manufacturing. These valves are designed to allow fluid to flow in only one direction, preventing back

When the pipeline feeds water from the water inlet, since the needle valve, ball valve, and float valve are normally open, the water enters the pool through the micro-filter, needle valve, control roo

1. Do not make the check valve bear the weight in the pipeline. The large check valve should be independently supported so that it is not affected by the pressure generated by the pipeline system. 2.

1. The disc is broken The pressure of the medium before and after the check valve is in a state of close balance and "seeing" with each other. The valve disc often beats with the valve seat, and the v

1. The opening and closing parts should be closed during transportation, and at the same time, the cylinder position should be protected by packaging, anti-vibration and anti-collision. 2. Regular mai
