Pressure Sustaining Valve

Description:
The valve instantly opens when the pressure in the pipeline exceeds the preset safe level, thus relieving excessive pressure from the pipeline. When the pressure returns to normal, the valve closes slowly, at an adjustable speed. The valves also can be used to sustain upstream pressure to a preset pressure value.

The pressure sustaining valve is mainly used in fire fighting or other water supply systems to prevent the occurrence of over pressure or maintain the pressure of a fire fighting water supply system. After the fire pump is shut down, the valves can also serve to reduce the impact caused by water hammer. It can also be used as the water hammer eliminating device in large water supply systems. The valve utilizes a self-cleaning screen installed at the inlet of the valves control system, so suspended particles of relatively big specific gravities and diameters can not enter the control system. This guarantees the smooth and unobstructed circulation of the system, thereby ensuring the safe and reliable operation of the valve.

Float Controlled Valve

Brief introduction:
The main valve is controlled by a float ball valve which locates on the top of tank or reservoir. The valve maintains the maximum water level of tank or reservoir continuously. Float controlled valve is a multi-function hydraulic control valve. The water level can be controlled below a preset elevation, which can be widely used in influent pipes of the pools and water tower in high-rise buildings, municipal domestic water systems, fire fighting facilities, factories and mines.

Flow Control Valve

Description:
The valve limits the flow rate in the pipeline to a preset rate, regardless of upstream pressure variations. The valves is controlled by pilot valves, which takes use of integrated orifice plate to detect flow rate represented by differential pressure, and the differential pressure is used to control the pilot valves to implement flow rate control.
