Ball valve and gate valve are two of the most commonly used valves for controlling the flow of fluid in plumbing or gas systems. These valves have similarities in application, but have different strengths to offer. This guide reviews the key differences between ball valves vs. gate valves, giving you the reference to choose the…
Among the usual structural designs of single-gate, double-gate, wedge, parallel and so on, the wedge double-gate and the wedge elastic gate are the most widely used ones. The former’s gate automatically coincides with the two sides of the seat, while the latter relies on the elastic groove in the middle of the gate wedge to…
Gate valve，for its low fluid resistance, a minor pressure differential, the flow direction maintenance ability, erosion endured sealing surface and flow noninterference, can be applied with a wide range of pressure and temperature. As a common block valve, it is widely used in the oil media of petroleum, chemical, fossil-fuel power plants and in the…
How does a ball valve work? A ball valve is a shut-off device that regulates the flow of a liquid or gas using a rotating ball with a hole. By turning the ball a quarter turn (90 degrees) around its axis, the valve either opens or closes, allowing the medium to pass through or blocking…
The double cut-off slab gate valve with diversion hole is mainly used to cut off the medium. It is a kind of pipeline valve, which is used in many industries, such as natural gas, oil, etc. Main features of slab gate valve Working principles of double block drain valve seat When the valve is closed,…
Butterfly valve has been a classic valve for decades. In the 1950s, butterfly valves were considered standard and widely spread around the world. Top Wells VALVE is constantly improving and bringing butterfly valve products to market. These products prove that Top Wells VALVE has been a leader in butterfly valves. The butterfly valve must be…
Why is the globe valve designed to be with low inlet and high outlet openings? The purpose is to make the flow resistance small and save effort when opening the valve. At the same time, when the valve is closed, the gasket between the valve housing and the bonnet and the packing around the valve…

Pneumatic steam ball valve is one of the most widely used industrial control instruments, mainly composed of pneumatic actuators and various types of common valves. Compared with electric valves, the actuator is different. Although it is relatively convenient to use without electric valves, it is more suitable in many situations than electric valves. And according…
At present, there are many ball valve structures and specifications in our market, and new products and structures are emerging. The ball valve for sale can be divided into many types according to its main characteristics and applications. The specific support mode of ball valve structure can lead to obvious change of ball valve structure,…
First, features of gate valve. A gate valve refers to a valve, of which the switch device (the gate) is in a vertical motion trail along the central path. It is mainly used for cutting off the media in the pipeline. The gate valve has a wide application range from the general cut-off devices with…
