For providing the centrifugal pumping industry with a constant glandwater flow rate to pump glands, - with backflow prevention. A constant pre-set maximum flow rate to centrifugal pump glands can be achieved irrespective of fluctuating gland-water supply pressure, gland condition, or centrifugal pump discharge pressure.
A constant supply of glandwater to the gland, ensures the life of expensive pump seals are maximised.
Can ensure that the slurry will not be unnecessarily diluted.
Prevents one centrifugal pump from robbing all the available gland water in the event of its failure, which could result in the simultaneous failure of all other glands supplied from the same water supply.
Minimise wastage of available water supplies
Constant glandwater flow rate
High pressure and high temperature handling
Corrosion and scale resistant assembly
The maintenance free design of the Maric valve uses the flow control rubber as the flexible sealing component in the non-return mechanism. The flexing of the control rubber under normal operating conditions prevents scale build-up on the rubbers surface, which ensures a reliable seal, even after extended periods of no reverse pressure.
Maric Flow Control Australia | Control Valves
Maric Flow Control is an Australian owned manufacturing engineering firm situated in Adelaide, South Australia.
Our Maric control valves maintain a constant pre-set flow rate of water, over a wide pressure range.
Established in 1963, and celebrating 50 years of manufacturing in 2013 – we have experienced rapid growth in recent years with up to 40% of our production distributed overseas.
For flow rate sensitive pumps, filters, pump glands and water distribution systems, the installation of these Maric control valves can offer many benefits and valuable protection.
The technology is based on a precision moulded rubber control ring in the valves body, with an orifice diameter that varies in response to the pressure differential applied to it. The greater the pressure, the smaller the orifice, and vice versa, thereby maintaining a constant flow.
