Ball of trunnion ball valve is fixed

Ball of trunnion ball valve is fixed, it does not move with medium pressure. Trunnion ball valve has floating seats.  The seats move with the medium pressure to tight the ball and seal ring to ensure sealing reliability. Bearings could be mounted in top shaft and bottom shaft, which reduces operation torque. This is widely used in valves with high pressure and big sizes. To decrease the operation torque and increase sealing reliability, lubricated ball valves are adopted in recent years. A special sealant is injected between sealing faces of lubricated ball valve to create a layer. This increase the sealing reliability while decreasing the operation torque, which is better for high pressure, big sized ball valves.

The ball valve's ease of operation

The ball valve's ease of operation, repair, and versatility lend it to extensive industrial use, depending on design and materials used. high pressure ball valves bodies are made of metal, plastic, or metal with a ceramic; floating balls are often chrome plated for durability. One disadvantage of a ball valve is that they trap water in the center cavity while in the closed position. In the event of a freeze, the sides can crack due to expansion of ice forming. Some means of insulation or heat tape in this situation will usually prevent damage. Another option for cold climates is the "freeze tolerant ball valve". This style of ball valve incorporates a freeze plug in the side so in the event of a freeze up, the freeze plug ruptures, (acts as a sacrificial disk), thus making for an easy repair. Now instead of replacing the whole valve, just screw in a new freeze plug. This is commonly called freeze plug technology.

A ball valve is a form of quarter-turn valve

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.
stainless steel ball valve are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff applications, where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications.

Need a valve that is easy to clean

Need a valve that is easy to clean? The stainless steel ball valve makes cleaning a breeze, which means keeping your valves up to sanitary code is made easy. The multi-purpose manual lever makes using the stainless steel ball valve simple. Since stainless steel is corrosion resistant, this valve can be used in a number of applications that include; gas, steam, water, and chemical utility services. The possibilities are endless with the stainless steel ball valve.

stainless steel ball valves as well as fittings

stainless steel ball valves as well as fittings are supplied to various industries. The products we are manufactured in both 316 and 304 stainless steel. With our exceptional prices and superb customer service we guarantee your purchasing experience will be second to none.
Stainless steel ball valves are almost a necessity in homebrewing.  These are most commonly used on your kettle, allowing you to control the flow of your liquids during transfers.  Using stainless steel is recommended, as these will come in direct contact with your wort, and using anything other than stainless could leave a metalic taste in your beer.  Stainless steel is also easier to keep clean, and will last longer.

The main features of Stainless steel needle valve

Stainless steel needle valve in the closed position, the valve is still there inside the pressurized fluid prior to maintenance, lift the front line pressure valve in the open position Instrument manifolds and make repairs before disconnecting the power or gas supply service, the actuator and bracket must first check out on the next ball, after removing the pressure downstream pipeline has indeed only exploded assembly operation and care must be taken to prevent damage to the decomposition of the sealing surface again when the parts assembly, especially the non-metallic parts. Stainless steel needle valve seal reliable, simple structure, easy maintenance, regular spherical surface and seal in the closed state, the media can not easily be eroded, easy operation and maintenance for water,Double ferrule fitting solvents, acids, and natural gas work in general media, and Stainless steel needle valve is also suitable for harsh working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., in various sectors has been widely used. Widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water, electricity, municipal, steel and other industries.

Trunnion ball valve preservation method described

Trunnion ball valve body's first anti-corrosion, the main choice of stainless steel, carbon steel. Although anti-corrosion materials is very rich, but whether the election was appropriate or not an easy thing, because the corrosion problem is very complex. Valve manifolds Choose body material difficulties, lies not only consider the corrosion problem, but must consider the ability to withstand temperature, whether economically justified, is it easy to buy and other factors. Followed Trunnion ball valve liner take measures, such as lead-lined, Instrument needle valve lining aluminum, plastic lining, the lining of natural rubber and synthetic rubber and the like. The medium conditions permit, This is an economical way. Again, under pressure, the temperature is not high, Check valve made with non-metallic valve body materials can often be very effective corrosion prevention and control. In addition, Trunnion ball valve has an outer surface exposed to atmospheric corrosion, general steel materials to paint to protect.
