Recently, due to exchange rate fluctuations, Chinese titanium dioxide producers have raised the spot price of titanium dioxide exports. The strong exchange rate of RMB against the US dollar resulted in lower export earnings of Chinese titanium dioxide than domestic market sales. Data show that on March 15, the spot price of titanium dioxide exported by China was 2250~2400 US dollars/ton, up 3.3% from the beginning of February.
Previously, as market participants returned to the spot market to replenish stocks, the market price of titanium dioxide rose after the Spring Festival. At the beginning of 2019, as the spot price has been steadily declining since the second half of 2018, Chinese titanium dioxide traders and distributors kept their inventories at a low level to reduce losses.
Chinese titanium dioxide producers said, “International suppliers will increase their second-quarter quotations to maintain a premium relative to Chinese exports.†Some Asian buyers are cautious because of fears that China's spot prices may rise further, and some of them hope to end negotiations on the second quarter contract as soon as possible.
The function of unloading valve for loader: the compressed air from the air pump enters the Air Brake Booster with constant pressure to ensure the safety of Loader Brake Clamp
Unloading valve for loader working principle: unloading relief valve is composed of relief valve and one-way valve. When the system pressure reaches the opening pressure of the relief valve, the relief valve is opened and the pump is unloaded; When the system pressure drops to the relief valve's closing pressure, the relief valve closes and the pump loads to the system.
Unloading valve is under certain conditions, can make hydraulic pump unloading valve. Unloading valve is usually a with two two-way valve solenoid valve is (often) the overflow valve, when the function is not unloading set system (pump) is used as the main stress, when unloading state (by two two-way valve action transformation) direct return tank pressure oil, the oil pump pressure drops to approximate to zero, in order to realize some loop control and improve the pump life, reduce power consumption.
In a circuit belonging to a merging circuit. The pressure reducing valve is used to adjust the pressure required by the executive element. It is connected in series in the loop and generally cannot be used interchangeably.
