Fire-Safe DesignIn case of fire, the nonmetal packing or seat (non-fireproof material) will be burnt, considerable medium leakage may possibly cause fire spread. Here, the fire protection structure functions to prevent medium from mass leakage. As shown in the figure, once the seat is burnt, the ball will directly contact the metal face on valve body, thus to prevent medium leaking out from the burnt seat. The design of fire protection and antistatic structure shall conform to the requirements of API607.

Anti-Static DeviceWhen operating the valve, friction between the ball and the nonmetal seat, like PTFE will produce electrostatic charge that can be accumulated on the ball. To prevent static spark, an antistatic device is placed on the valve to derive the electric charge accumulated on the ball from the static channel between the ball and the stem, or between the stem and valve body.

Blow-out ProofWhen medium passes through the valve, the pressure in valve body may possibly push the stem out , or when the valve is in repair, if there is pressure in the middle cavity, the stem or medium seems to easily fly out upon disassembling the valve, which can cause injuries to human beings. To prevent these possibilities, a dummy club is placed at the lower part of the stem. In this way, even if there is fire, packing and thrust bearing are burnt or packing is damaged due to other causes, the pressure of medium in valve body will make the dummy club of valve stem in close contact with the upper seal face of valve body, thus to prevent medium leaking out from the damaged packing position.

Full and Reduced BoreWe have ball valves of full and reduced bore to meet users’ different needs. Full bore ball valves have the same inside diameter as that of pipeline, with the lowest fluid resistance for the convenience of cleaning the pipeline. While reduced-bore ball valves weighs only 70% of the full bore ball valve with the same caliber, a saver cost and price, and its fluid resistance coefficient is only 1/7 of that of the globe valve with the same caliber, so that reduced bore valves are widely used abroad.

Valve Locking DeviceTo prevent mis-operation, fully opened or closed position of valve can be locked up, especially when valves are not allowed to be opened or closed by technical process. To prevent mis-operation by other persons, it seems very important to have valve position locked up. Thereby, locking hole locating tab is designed if requested by users to meet the technological requirements of users.

First Aid of SealThe valve is designed with an auxiliary seating emergency system, as shown in the figure. In case of soft seal damaged, or failure of seal in an emergency circumstance, emergency seal may be affected by injecting in sealant through auxiliary sealing system. If needed, emergency seal assembly can be used to rinse and lubricate the seating area. Plus, valve stem can also be designed with an auxiliary emergency sealing system.

Fire-Safe DesignPlant fires have become an increasingly serious concern due to the installation of a greater number of soft seated valves in place of conventional metal seated valves in many refineries and plants. In case of fire, the nonmetal packing or seat (non-fireproof material) will be burnt, considerable medium leakage may possibly cause fire spread. Here, the fire protection structure functions to prevent medium from mass leakage. As shown in the figure, once the seat is burnt, the ball will directly contact the metal face on valve body, thus to prevent medium leaking out from the burnt seat.

Anti-Static DeviceWhen operating the valve, friction between the ball and the nonmetal seat, like PTFE will produce electrostatic charge that can be accumulated on the ball. To prevent static spark, an antistatic device is placed on the valve to derive the electric charge accumulated on the ball from the static channel between the ball and the stem, or between the stem and valve body.

Blow-out ProofWhen medium passes through the valve, the pressure in valve body may possibly push the stem out , or when the valve is in repair, if there is pressure in the middle cavity, the stem or medium seems to easily fly out upon disassembling the valve, which can cause injuries to human beings. To prevent these possibilities, a dummy club is placed at the lower part of the stem. In this way, even if there is fire, packing and thrust bearing are burnt or packing is damaged due to other causes, the pressure of medium in valve body will make the dummy club of valve stem in close contact with the upper seal face of valve body, thus to prevent medium leaking out from the damaged packing position.

Middle Flange Leak-tight structureThe connection between valve body and the left body is sealed by gasket. To prevent seal leakage resulted from fire, high temperature or vibration etc, the valve body is designed metal to metal contacted, thus to form up seal flange to ensure leak tightness.

Valve Locking DeviceTo prevent mis-operation, fully opened or closed position of valve can be locked up, especially when valves are not allowed to be opened or closed by technical process. To prevent mis-operation by other persons, it seems very important to have valve position locked up. Thereby, locking hole locating tab is designed if requested by users to meet the technological requirements of users.

Double Block and BleedEach seat of the valve can separately cut off the medium at both inlet and outlet of the valve to perform double block functions. When the valve is closed, body cavity and two of the body ends can be blocked with each other even if both the inlet and outlet are under pressure, when the medium left in the body cavity might be bled through the relief valve.

Discharge DeviceIf requested by users or by the system, discharge valve may be mounted on the body of ball valve. In case the two ends of valve have been sealed, the pressure in valve will be released through the discharge valve on the body. Besides the function of double block and bleed, this discharge device also functions to rinse and blow-out the deposits inside valve body.

ActuatorsValves with DN150 and higher diameters should be provided with actuators. Actuators are in three types: Gearbox; Pneumatic & Electrically operated. Appropriate choice for particular operations shall be advised according to users’ requirements. The actuators are also available for DN150 and lower diameter valves.

Self RelievingSeat is designed in such a way that the differential area A = C - B has greater force than the spring load. In the reverse pressure direction (pressurized from the cavity), the single piston effect seat will relieve pressure when the reverse load overcomes the spring force and pushes the seat away from the ball. P>P1

Single Piston EffectAs line pressure increases, the seat differential area A = C - B creates a piston effect forcing the seat against the ball. Piston effect force is greater than body cavity and reverse pressure (P1> P). Consequently a tight seal comes into effect on the contact circle.

The torque ratings listed below are for the reference to choose a drive device. The properties of medium, trims and valve open frequency shall be considered as extra factors. For instance, valves with corrosion-resistant trims to deal with clean and lubricating mediums, their torque may be lowered by 20%. However, to deal with stringent mediums like slurry, granular medium and oxygen, the torque may be increased by 50%. The operating torque of drawing-down valves is subject to the corresponding diameter to their neckings.
