The pressure difference Pang Tong balance valve is installed on the pipeline between the water supply and the return water, and controls the opening and closing of the main gate according to the pressure difference between the inlet end and the outlet end, and the reaction is accurately and quickly controlled. The closing speed is adjustable, and the valve closes smoothly without pressure fluctuations.

The electric control valve is installed at the water inlet of the water tank. According to the electrical signal or manual operation, the valve is opened or closed, the reaction is accurately and quickly controlled, the closing speed is adjustable, and the valve is closed smoothly without pressure fluctuations.

The pressure relief valve is installed on the pipelines of high-rise buildings, fire water supply systems and other water supply systems. When the pressure in the water supply pipeline exceeds the pressure set by the pressure relief valve, the pressure relief valve automatically opens to quickly relieve pressure to protect the safety of the pipeline. It can be used as a pressure-holding valve. When the pipeline pressure is lower than the set pressure, the main valve is closed to ensure the water supply pressure upstream of the main valve.

Slow-closing check valve is the only valve that is installed at the water pump outlet of the water supply system of high-rise buildings and other water supply systems to prevent media backflow, water hammer and water hammer. An intelligent check valve that uses the pressure of the medium itself to control and have a time-delay shut-off function to relieve water hammer.

The pressure reducing valve is a special valve installed on the water supply and drainage pipelines of high-rise buildings to reduce the inlet pressure to a certain outlet pressure. The valve relies on its own energy to keep the outlet pressure stable at the set value, that is, the outlet pressure does not change due to changes in inlet pressure and flow.

The electromagnetic remote control float valve is a double safety water operated valve with two functions of a distance solenoid valve and a remote control float valve. It is mainly installed at the water inlet of the pool or high-priced water tower. When the water level reaches the set height, the main valve is controlled by the floating ball pilot valve to close the water inlet to stop the water supply. When the water level drops, the main valve is controlled by the floating ball pilot valve to open the water inlet and inject water into the pool to achieve automatic water replenishment.

The remote control float valve is a hydraulically operated valve with multiple functions. It is mainly installed at the water inlet of the pool or elevated water tower. When the water level reaches the set height, the main valve is controlled by the float pilot valve to stop the water supply. After the water level drops, the main valve is controlled by the floating ball pilot valve to open the water inlet and fill the pool with water to achieve automatic water replenishment.

The 388 brass electric control valve is installed in the pipeline system and can be used as a remote opening or closing function. At the same time, it can be equipped with a speed control device, which can replace the gate valve or butterfly valve used for opening and closing. The large-scale electric operating machinery is easy to maintain.

Brass pressure relief: It can release the pressure in the water supply pipe that exceeds the safe setting value of the pilot valve, and maintain the pressure in the pipeline below the safe setting value to prevent the high pressure or sudden pressure in the pipeline from damaging the pipeline system or equipment.

黄铜缓闭式止回阀具有调控开启和关闭速度的止回阀，单开启或停止抽水机运转时，可配合现场调节至最佳开启和关闭速度，可用于高层建筑，减少水锤及水击现象产生，以达到安静关闭之效果。

The brass pressure reducing valve controls the outlet pressure of the main valve. When the single inlet pressure is 1.6MPa, the outlet pressure is 0.15-0.8MPa. When the inlet pressure decreases, the outlet pressure decreases accordingly. It can be used in domestic water supply, fire fighting systems and industrial water supply systems.

The brass remote control float valve controls the liquid level of the water tower or pool. It is simple to maintain, flexible and durable, and the liquid level control accuracy is high. The water level is not disturbed by water pressure and is closed tightly without leaking.
