Ansi Titanium Ball Valve

ANSI 150LB Titanium Floating Ball Valve

Material contact parts Titanium material TA1/TA2/TA9/TA10, other parts AISI 304 certification: PED, 97/23/EC
Optional valve type: straight ball valve, three piece ball valve, three-way ball valve manual, pneumatic, electric
Ball core type: T type, L type, straight through type

Material: titanium TA1/TA2/TA9/TA10, or customized dual phase steel 2205, super dual phase steel 2507, monel alloy, 904L, Hastelloy, etc

Overview of ANSI 150LB titanium floating ball valves:
1. The movable metal valve seat structure preloaded by cylindrical spring or wave spring is adopted. The design of sealing preload is reasonable, and the opening and closing are flexible, effectively ensuring the reliability of sealing.
2. The valve rod with special structure device not only ensures that the filling place will leak, but also prevents the valve rod from coming out.
3. According to the needs of users, it can be designed to adapt to dust (including solid particles), slurry and other media, so that the ball valve has better wear resistance and high temperature resistance.
4. It has fireproof and anti-static functions.
5. The ball valve of this structure shall be used according to the specified flow direction.

Features of ANSI 150LB titanium floating ball valves:

1. Labor saving operation: the ball is supported by upper and lower bearings to reduce friction, which causes excessive torque due to the huge sealing load formed by the ball and seal seat driven by the inlet pressure.
2. Reliable sealing performance: PTFE single material seal ring is embedded in the stainless steel valve seat. A spring is set at the end of the metal valve seat to ensure sufficient preload of the seal ring. When the sealing surface of the valve is worn during use, the valve continues to ensure good sealing performance under the action of the spring.
3. Fireproof structure. The fire resistance test meets the requirements of APl6FA and APl607 standards.
4. Automatic pressure relief function: when the pressure of the stagnant medium in the valve chamber rises abnormally and exceeds the pre tightening force of the spring, the valve seat moves back and leaves the ball, achieving the effect of automatic pressure relief. After pressure relief, the valve seat automatically resets.
5. Drain pipeline: drain valve L is set up at both the upper and lower parts of the valve body to check whether the valve seat leaks. During operation, when the valve is fully open or closed, the pressure in the middle chamber can be removed and the packing can be replaced directly; It can discharge the residues in the middle chamber to reduce the pollution of the medium to the valve.
Titanium symbol Ti, atomic number 22, belongs to refractory rare light metal. It is a silver white metal with low density, high melting point, high specific strength, strong corrosion resistance, good high and low temperature performance, non-magnetic, non-toxic, and good biocompatibility. Among them, the high specific strength performance is particularly outstanding. The strength of high-strength titanium alloy is equivalent to that of high-strength steel, but the density is almost half. In addition, titanium and its alloys also have the characteristics of shape memory, superconductivity and hydrogen storage. At present, titanium and its alloys are widely used in chemical industry, ocean engineering, aerospace, military, metallurgy, medical, sports and leisure and other fields. Therefore, titanium is a strategic metal and an indispensable key material in the field of modern high-tech. It is also known as “space metal” and “ocean metal”. Titanium is a metal with high chemical activity, which has excellent corrosion resistance to most corrosion media. Titanium has a great affinity with oxygen. When it comes into contact with the atmosphere or any oxygenated medium, a solid and compact passive oxidation film is formed on its surface immediately. This kind of film is very stable. If mechanical damage occurs, as long as there is a certain amount of oxygen, the film will be formed again immediately.

Titanium valve mainly uses titanium metal material to have good stability and self passivation ability in strong corrosion environment, which can resist strong corrosion under various harsh conditions. Whether titanium valve can resist the corrosion of working environment medium depends on the chemical stability of the “passive oxide film” on its surface in the corrosive medium. For neutral, oxidizing, weak reducing medium environment, “passive oxide film” itself has good stability. For reducing corrosion media with high temperature or low PH value, in order to improve the stability of its “passive oxide film”, corrosion inhibitors (such as air, water, heavy metal ions and anions) can be added, such as titanium surface ion modification, anodizing, etc., to improve the corrosion resistance and surface hardness of “titanium” in reducing media to meet the use requirements.

Application of titanium valve titanium and titanium alloy is a new and promising metal material. It has the outstanding advantages of light weight, high strength, corrosion resistance, good pressure resistance, etc., and is widely used in aviation, space development, marine engineering, petroleum, chemical, light industry, food processing, metallurgy, power, medicine and health, instrumentation and other industries. Titanium also has excellent seawater corrosion resistance and seawater scouring resistance, so it has become a “new star” in seawater corrosion resistant materials for ships, and has been widely used in ships, coastal power plants, and seawater desalination. Product classification of titanium valves: titanium ball valve, titanium butterfly valve, titanium gate valve, titanium globe valve, titanium check valve, titanium plug valve, titanium discharge valve.

What is a backseat of Gate Valve

/in , /by

What is a backseat?A backseat is a seating arrangement inside the bonnet. It provides a seal between the stem and bonnet and prevents system pressure from building against the valve packing when the valve is fully open. Back seats are often applied in gate and globe valves (source: wermac.org).
How to use the backseat?
The backseat should only be used to isolate the gland packing from the line medium for example when gland packing leakage is evident and until the valve can be de-pressurised and repaired.
How to not use the backseat?
Under no circumstances should the  backseat be used to allow gland packing replacement or repair while the valve and system are pressurized.Having clarified these 3 questions, the issue seems quite simple.
But it is not!One of the most common errors done on site is to believe that if the Gatevalve is back-seated (fully open position – and backseat sealing made), this will help to prevent wear of the packing rings.
Unfortunately using the back seat  in this way over a longer period of time, could  result in some serious issues:a)  Since the body, bonnet, stem, and disc heat up and expand at different rates, experience shows that valve can get jammed/blocked in back-seated positon.b) The gland packing will dry out since it’s not exposed to the steam, and could immediately blow upon closing of the valve.The simple but important rule for valve users, preventing misuse of the backseat!“Once the valve is brought into fully open position (back-seated), turn the hand wheel back one full turn”(this should be clearly stated in every Installation, Maintenance and Operating Manual of Valve Manufacturers),The other issue valve users experience is the problem with actuated valves. It does not matter if electric-, pneumatic- or hydraulic actuators are used. If the valve manufacturer does not correctly adjust the actuator in the open position, we will get back to the same problems (as described earlier). Field experience on high pressure/temperature drain valves (globe valve), pneumatically actuated and usually in fail safe open position, showing clearly the premature use of the gland packing rings.
