Here is the brief introduction of stainless steel pneumatic ball valves. The stainless steel pneumatic ball valve is composed of stainless steel ball valves configured with the pneumatic actuator. The pneumatic actuator is divided into the double acting pneumatic actuator and the single acting pneumatic...

Here is the table of the manufacturing specifications of floating ball valves. Manufacturing specifications of floating ball valves (API/GB) Content API series GB series Basic design specification API 6D GB/T 12237 Basic design specification API 6D GB/T 12237 Pressure and temperature class ASME...

Pneumatic valves are driven by compressed air. There are only clear specifications, categories, pressure to meet the procurement requirements of the practice when purchasing the pneumatic valve. It can be used to control the flow of air, water, steam, all kinds of corrosive media, mud, oil, liquid metal...

The United States invented the butterfly valve in the 1930s. In the 1950s, it was introduced to Japan. In the 1960s, it was widely used in Japan. The promotion of butterfly valves in China was in the 1970s. The main characteristics of butterfly valves are small operating torque, small installation space...

The performance characteristics of stainless steel ball valves:   1. No maintenance, adjustment and lubrication. The installation of stainless steel ball valves is easy. The operating cost is low. The long-term operation is reliable. The surface adopts plastic spray processing technology, which...

We are very familiar with the stainless steel ball valve. However, compared with some industrial field veterans, some industrial field novices are very strange to the stainless steel ball valve. The composition of a big machine is generally composed of many small screws, valves, ball valves and other...

The cast steel globe valve is force-sealed. When the valve is closed, pressure must be applied to the disc to force the sealing face not to leak. When the medium from below the valve disc into the valve, the resistance is required to overcome the operation force. It is the friction force of the stem,...

1. The brief introduction of valves   The valve is used to control fluid flow, pressure and flow direction of the device. It is the pipeline conveying system control component. The controlled fluid may be liquid, gas, gas-liquid mixture, or solid-liquid mixture. The control function of the valve...

This article is about the differences between forged steel valves and cast steel valves. Which one is good?    The cast steel valve is one kind of cast alloy. Cast steel can be divided into cast carbon steel, cast low alloy steel and cast special steel. Cast steel is a kind of steel casting...

Many valves are now essential control components in all kinds of piping systems, such as globe valves, gate valves, butterfly valves, check valves and ball valves. Each valve is different in appearance, construction and even function and usage. However, globe valves and gate valves have some similarities...
