For road-crossing where the fluid carrying pipe cannot be buried directly. The movement of heavy vehicles will transfer impact loads and can damage pipeline with leaking water or gas etc. In all such cases, the carrier pipe is inserted into a sleeve pipe. Spacers allow the carrier pipe to be easily pulled into the existing sleeve pipe and the traffic loads do not reach the main service pipelines. Small size carrier pipes DN50 to very large DN3000
Maintaining hydraulic balance in water transmission and distribution systems is crucial to system efficiency.
Pressure Reducing Valves help accomplish this by reducing high inlet pressure to a lower constant predetermined delivery pressure.
They are the most commonly used control valves.
Solenoid Control Valves are simple electrically activated on/off valves that can be of critical importance in controlling flow in every water system.
The electrical signal used to activate the solenoid can be sent from timers, relays, clocks, pressure, level or flow transmitters, etc.
