2. 900X Emergency Shut-Off ValveThe 900X emergency shut-off valve belongs to a kind of valve that is intended for use in a water supply system in which the fire fighting water and domestic water are connected in parallel and for the control of the direction of water supply ...
2. 800X Pressure Difference Balance ValveThis valve can increase the utilization factor of a system, maintain the pressure difference at a precise constant value, and maximally reduce the system noise and avoid damages caused to the equipment because of an excessive pressure difference...
2. 700X Pump Control ValveThe 700X pump control valve is a kind of check valve intended for installation at outlets of pumps in high-rise buildings and other water supply systems to prevent reverse flow of the medium. When the pump is about to stop water supply, the valve first shuts off slowly by about 90% so as to avoid water hammer caused by the sudden...
2. 600X Electrical Control ValveThe 600X electrical control valve is a kind of waterpower operated valve that utilizes a solenoid valve as its pilot valve. It is normally used in automatic control for water supply and drain systems and other industrial systems. The valve is precise and quick in its response in the process of control and utilizes remote operations through turning...
2. 500X Pressure Relief or Sustaining ValveThe 500X pressure relief valve is mainly used in fire fighting or other water supply systems to prevent the occurrence of overpressure or maintain the pressure of a fire fighting water supply system. After the fire pump is shut down, the valve can also serve to reduce the impact caused by water hammer. The valve can also be used...
2. 400X Flow Control ValveThe 400X flow control valve is a multifunctional valve that adopts the mode of flow control employed by high-precision pilot valve. It is suitable for use in water distribution pipes within which the flow and pressure need to be controlled, and can serve to keep the preset flow constant, restrict excessive flow at a preset value and reduce...
2. 300X Flow Control Check ValveThe 300X flow control check valve is an intelligent valve intended for installation in the pump outlet of a high-rise buildings' water supply system. It effectively prevents the reverse flow of a medium, as well as water hammer-type phenomena. This valve utilizes a motorized valve, check valve and water hammer eliminator at the same ...
