  • Freeze Protection And Maintenance Of Valves In Winter
    2020-12-25
    As winter approaches, the temperature gradually drops and the valves outsides are getting greater chance tobe froze. At this time, the pipeline will easily fail if not take some acts. And when it comes to some high-risk working conditions, accidents may also occur. Therefore, the anti-freezing treatment of valves is crucial to industrial equipment. Before th...

  • TYPES OF PLUG VALVES
    2020-10-16
    There are four common types of plug valves, each of which has specific characteristics and advantages. Lubricated plug valve The lubrication plug valve uses lubricant to reduce frictions and make each port tightly sealed. Lubricants are basicly base oils that increase the viscosity of moving parts, such as amorphous or fumed silica, which are injected between the valve plug surface and the valve b...

  • Valve Corrosion Prevention and Treatment
    2020-09-11
    What is valve corrosion? Corrosion of valves is usually understood as the damage to the metal materials of the valve caused by the chemical or electrochemical environment. Since the corrosion appears in the spontaneous interaction between the metal and the surrounding environment, the focus of corrosion prevention is how to isolate the metal from the surrounding environment or more use of non...

  • How to Choose Valves Used for High Temperature Conditions?
    2020-09-04
    The high-temperature conditions here refer to the conditions when the medium temperatures are equal to or higher than the starting creep temperatures of the metallic materials. The creep temperature of carbon steel is about 400℃; chromium molybdenum alloy steel 450℃; austenitic iron-based high-temperature alloy steel 540℃; nickel-based high-temperature alloy 650℃; aluminum alloy 200℃; titanium all...

  • Have you paid attention to these thing of cryogenic valves
    2020-07-31
    Installation requirements for cryogenic valves Due to the special structure of cryogenic valves, the installation of cryogenic valves also has special requirements. Because of the long-neck bonnet of the cryogenic valve, cryogenic gate valves must be installed vertically upward, with the stem direction within a 45-degree angle. And it should also be avoided as much as possible to install...

  • Intro to Lug and Wafer Type Butterfly Valve
    2020-07-16
    Butterfly valves have been around for a long time and are used in a variety of applications. They made their debut in the 1930's and have been used in several industries ever since. There are several different types of butterfly valves, but they fall into two basic types - lug valves and wafer valves.   A butterfly valve is recognized as a "quarter-turn" valve. The valve is designed...

  • The working of ball valve
    2020-06-29
    Ball valves are usually found in controlling the flow of high-weight fluids and gas lines. This is because that these valves don’t reduce the flow weight and limit liquid flow. Ball valves are dominantly put in where the supply pipe’s internal breadth is 6 inches or less. A ball valve is a valve used to divert the flow. When open, it gives access to the medium and when closed, it cuts off the medi...

  • Choose between bronze and brass valves
    2020-06-23
    Bronze and brass are two of the most common materials used to produce valves. This preference comes because both metals are quite malleable. They both are artificially made from natural metallurgical elements: brass is made from copper and zinc, while another is made primarily from copper and tin. Each metal offers valves numerous and various advantages...

  • Knife Gate Valve vs. Gate Valve
    2020-06-12
    The biggest difference between a knife gate valve and a flanged gate valve is that gate valve is manufactured according to ANSI , while knife gate valve meets TAPPI Standards. Gate valves are also flanged, wider in size, ANSI pressure rated, and their API leak tightness standards need to be met as well. Gate valves are bi-directional, widely used in fluid applications, and they only come with meta...
