Gate valves are available with a variety of disks. Classification of gate valves is usually made by the type disk used:Wedge type single gate valve,Resilient gate valve,Double gate type gate valve, or Parallel gate valve. 1）Wedge type single gate valve ①Simpler structure than resilient gate valve. (ii) At higher temperatures, the sealing performance is not as good as that of resilient gate valves ...

The emergence of the triple eccentric butterfly valve, or triple offset butterfly valve, has changed the stereotype of the butterfly valve. In the past, people usually thought that butterfly valves could only be used on ordinary pipelines at normal temperature and low pressure, and were not resistant to high temperature or high pressure.   Buttriple eccentric butterfly valves have d...

With the continuous development of industry, there is an increasing demand for ball valves, especially ball valves under high temperature and high pressure harsh conditions. Ball valves are required to have higher performances such as wear resistance, erosion resistance, high temperature resistance, and corrosion resistance. Although the traditional full-bore ball valve has surface hardening treat...

Overview Ultra-low temperature butterfly valves are mainly used in pipeline systems of liquefied natural gas and liquid nitrogen to control the opening and closing or adjustment of the pipeline equipment. The product adopts a double offset structure and an elastic metal sealing structure. The double offset structure can greatly eliminate unnecessary overloading and scraping of the disc and sealing...

The main difference between the double jacket gate valve and the ordinary gate valve lies in its special double jacket structure. This structure allows the double jacket gate valve to operate over a broader temperature range and provides more precise control over the fluid temperature. Here are some key distinctions: Double jacket structure Double Jacket Gate Valve: Features a dual-layer jacket st...

1. What are the three main factors to consider when selecting an actuator? 1) The actuator’s output must exceed the valve's load and be appropriately matched. 2) When checking standard combinations, ensure that the allowable pressure differential specified for the valve meets process requirements. For high pressure differentials, calculate the unbalanced forces on the valve core. 3) Consider wheth...
