Insert Valve bodies

Maric Insert type valves are the relatively small flow control valves intended for press or slip fitting inside other equipment e.g. specially prepared housings, manifolds, or water meters and meter tails.

Maric Flow Control Insert Valves are available in two main insert types:
Plain inserts. Plain inserts are dimensionally the smallest possible housing that will accommodate a flow control rubber. They are designed to be press fitted into other components.
They are available in 5 sizes. (One for each series control rubber). Modified appropriately, they accommodate all Maric’s available flow rates up to 233 lpm.
Originally developed for the company’s own internal purposes, they have become useful to customers who manufacture their own equipment. This equipment, eg, a special fitting, valve manifold or sprinkler head, would be machined by the OEM, to a particular bore diameter and length, to enable the Maric insert to be pressed in. Once pressed in, they are generally not removable.

Special inserts. These are specially made to suit customer’s specific dimensional requirements for their OEM equipment. Typically machined from brass, one common application (pictured), is for fitting (hiding) them inside municipalities water meters.
They are generally fitted with an o’ring, for the purpose of sealing and holding the insert in place. These are relatively easy to remove and are also available in PVC and stainless steel.

What the Maric Valve does

The Maric Flow Control valve is designed to deliver a fixed, pre-set, constant (maximum) flow of water – irrespective of pressure differential across it within a given range, typically 140-1000 kPa.
This means constant flow rate, irrespective of fluctuating pressure upstream or downstream of the valve.

Control rubbers, together with the shape of their enclosure, controls the flow rate.
