Pressure Relief/Sustaining Valve
Model : 500HCV
Brand : aikon
Share :
A hydraulically operated and controlled pilot valve,Use for urban water supply and industrial, agricultural water transmission lines, etc
The Aikon 500HCV Pressure Relief Valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges.
Operation is completely automatic and pressure settings may be easily changed. This valve can be used for pressure relief, pressure sustaining, back pressure, or unloading functions in a bypass system.If a check feature is added, and a pressure reversal occurs, the downstream pressure is admitted into the main valve cover chamber,closing the valve to prevent return flow.
Pressure Relief application
This fast opening, slow closing relief valve provides system protection against high pressure surges on pump start up and pump shut down by dissipating the excess pressure to a safe location.
Pressure Sustaining Service
When installed in a line between an upper zone and a lower area of heavy demand, the valve acts to maintain desired upstreampressure to prevent "robbing" of the upper zone. Water in excessof pressure setting is allowed to flow to an area of heavy demand,control is smooth, and pressure regulation is positive.

New type electric motor soft starter
CMC-MX motor soft starter is a sort of new type motor starting protector combining electronic technology microprocessor and automation. It is able to stably start and stop motor without step change, which perfectly avoids mechanical and electrical impact as a result of using direct start, Y-△ start and auto-induction voltage-reduced start to start motor and can effectively reduce starting current and distribution capacity. At the same time, as CMC-MX soft starter has current transformer and contactor built inside, user does not need to externally connect the both to soft starter.

Self priming trash pump
MCT series pumps are designed for economical, trouble-free operation. The superior solids handling capabilities of the pump make it ideally suited for a variety of applications including solids-laden liquids and slurries. In addition, the large volute design allows automatic repriming in a completely open system without needing suction or discharge check valves.
