High Temperature Ball Valves India

May. 08, 2020

The high-temperature ball valve is metal seal structure, seal form is metal to metal seal, can replace the metal seal ring to metal seal, stainless steel plate, and graphite composite plate seal ring to metal seal. Hard seal butterfly valve drive form in addition to the electric manual, worm gear drive, pneumatic, etc. The disc of the high-temperature ball valve is installed in the diameter direction of the pipe. In the hard seal ball valve body cylindrical channel, the disc-shaped disc around the axis of rotation, rotation Angle is 0°~90° between, rotation to 90°, the valve is fully open.

High-temperature ball valves applications

A corrosion-resistant ball valve, hard sealed butterfly valve as a part used to realize pipeline system on and off and flow control, has been widely used in many fields such as petroleum, chemical industry, metallurgy, water, and electricity. In the known butterfly valve technology, the sealing form of the seal structure, sealing materials for rubber, polytetrafluoroethylene, and so on. Due to the structural characteristics of the restrictions, not suitable for high temperatures, high pressure, and corrosion resistance, wear-resistance, and other industries.

The cautions of high - temperature ball valves

1. As the multi-layer hard and soft sealing ring is fixed on the valve plate, when the valve plate is normally open, the media forms a front flush to its sealing surface. The soft sealing belt in the interlayer of the metal sheet directly affects the sealing performance after being flushed.

2. by the structural conditions of the structure is not suitable for the size of the valve below DN200, the reason is the overall structure of the valve plate is too thick, flow resistance.

3. because of the principle of three eccentric structure, the sealing surface of the valve plate and the seal between the seat is by the torque of the transmission device valve plate pressure to the seat. Under positive flow conditions, the higher the medium pressure, the tighter the sealing extrusion. When the flow channel medium countercurrent with the increase of the medium pressure between the plate and the seat of the unit positive pressure is less than the medium pressure, the seal began to leak.

The characteristics and principle of high-temperature ball valves

High-temperature ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation, and maintenance, and is applicable to water, solvent, acid, and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane, and ethylene, widely used in various fields. The ball valve body may be integral or modular.

The high-temperature ball valve has a rotation of 90 degrees of action, the plug body for the ball, a circular hole, or channel through its axis. Ball valve in the pipeline is mainly used to do cut off, distribution, and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small torque can be closed tightly. Ball valves are best used as a switch and cut-off valves, but recent developments have designed ball valves for throttling and flow control purposes, such as v-shaped ball valves.
