The Dead man Lever Type Valve The three-piece spring automatic reset ball valve is a relatively new type of ball valve. The valve seat adopts elastic sealing structure, which is reliable and easy to open and close. The valve stem adopts downloading structure with reverse seal, and the valve stem will not be washed out when the valve chamber is abnormally pressurized. The advantage of spring automatic reset ball valve is that it can reset automatically without manual closure, which not only saves time and labor, but also avoids the loss of medium flow. The main characteristics of spring automatic reset ball valves are small fluid resistance, simple structure, small size, light weight, compact and reliable, easy operation, convenient maintenance, three-piece ball valves are widely used in petroleum, chemical industry, urban water supply and drainage and other strict cut-off conditions. The three-piece spring automatic reset ball valve is composed of three-piece ball valve and spring handle. The main principle of spring automatic reset ball valve is that a spring handle is installed on the basis of three-piece ball valve. Its working principle is to reset automatically by triangular lever and spring compression spring. This product is also called spring automatic return ball valve, spring automatic close ball valve, spring automatic return ball valve, spring automatic return ball valve, etc. Their products all have the same function, but they are called differently.

Trunnion Mounted Ball Valve

Trunnion Mounted ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in design, and it is suitable for various corrosive and non corrosive media. Compared with floating ball valves, during operation, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, which does not cause the ball to move towards the valve seat. Therefore, the valve seat will not bear excessive pressure. Therefore, the torque of the fixed ball valve is small, the deformation of the valve seat is small, the sealing performance is stable, and the service life is long. It is suitable for high-pressure and large-diameter situations. Advanced spring pre seat components with self tightening characteristics achieve upstream sealing. Each valve has two seats that can be sealed in each direction, so there is no flow restriction during installation and it is bidirectional. This valve is generally installed horizontally.

Forged Trunnion Ball Valve

With all advantages of Trunnion Mounted Ball Valves, Forged Steel Line are available in types of Two Piece Split Body & Three Piece Bolted Body. The forging material can ensure sufficient rigidity and strength under maximum rated operation pressure. Without inherent flaw of cast. Enough wall thickness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe.The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work conditions. All Trunnion Mounted Forged Ball Valves are designed and manufactured to the most updated international standards API 6D, ASME B16.34, BS 5351 or equivalents. With standard features of Fire Safe, Anti-static and Stem Blow-out Proof

1 PC Screwed End Ball Valve

The one piece female thread connecting ball valve is of integrated structure. The valve body is cast using advanced process, reasonable in structure and elegant in appearance; the valve seat is of elastic seal structure, reliably sealed and easily opened and closed; the valve rod is of bottom mounting structure with back seal, and will not fly out in case of abnormal pressure rise inside the valve cavity. The valve can be equipped with 90° switch locating mechanism. The valve can thus be locked as required to prevent accidental operations. There are three drive modes, manual, electric and pneumatic modes.

Floating DBB Ball Valve

Double Block and Bleed Valves assure double isolation function thanks to two obturator inserted in a single body and they provide the bleed function by means of a bleed/vent system located between obturators(body port and ball, gate or needle valve), from the floating ball valve design.

Floating Ball Valve

1. Its opening and closing part is a ball, the ball rotate around the axis of the stem 90 degree to achieve the purpose of opening and closing the fluids in the pipeline. 2. Simple structure, good sealing performance and small torque 3. Bolted bonnet, Two-piece Body, Floating Ball 4. Full or reduced bore, Blowout Proof Stem 5. Fire safe and Anti static 6. Low leakage packing material 7. Locking device equipped 8. Flange mounted on the top

Cryogenic Ball Valve

MAIN FEATURES: • Metal to metal sealing • Triple eccentric quarter-turn design • Torque seated • Bi-directional tight shutoff • Zero leakage • Non-rubbing seating • Inherently fire safe and fire tested

Top Entry Ball Valve(Floating Ball)

The top mounted ball valve is easy to disassemble and quickly maintain on the pipeline. When the valve malfunctions in the pipeline and needs to be repaired, there is no need to disassemble the valve from the pipeline. Simply remove the middle flange bolts and nuts, remove the valve cover and valve stem assembly together from the valve body, and then remove the ball and valve seat assembly. The ball and valve seat can be repaired online. This type of maintenance saves time and minimizes losses in production.

Metal Seated Ball Valve

With such features as small fluid resistance, smooth flow channel, rapid opening and closing, and easy automatic control, the ball valve has been widely used. But the seat of regular ball valves is generally made of PTFE and other nonmetal materials. Limited by seat materials, the regular valves cannot be used under the service condition of high temperature. Therefore, the use of regular ball valves is limited to a certain degree. The series of new style practical metal seated ball valve products are newly designed to solve the above problem, and have been widely applied in petroleum, chemical industry, e electric power, metallurgy, light industry and etc.
