Maric flow control valves automatically and accurately limit water flow rate to a constant pre-set rate.
Body sizes range from 1/8" BSP, up to 300mm.
Flow rates are available from 0.4 up o 13000 litres per minute.
Control is achieved by means of a pressure sensitive, variable orifice, rubber control ring, whose orifice diameter reduces as pressure differential increases, and increases as pressure differential reduces. Thus maintaining constant flow.
Flow rate accuracy (Precision type) is within +/- 10% of rated flow.
Pressure differential range is from 140 - 1000 kPa.
Other pressure differential ranges include; 40 - 300 kPa, 140 - 1500 kPa,
170 - 2000 kPa
Body materials include Brass, PVC, Gunmetal, & 316 stainless steel
Control Rubber materials include Nitrile, EPDM & Viton
Valves consist of;
- A body manufactured to international engineering standards
- A precision machined recess for the control rubber, and
- A pressure sensitive control rubber, meticulously
compounded to pass
exacting flow tests
Ever since water has been piped, there has been a need for an accurate and inexpensive method of controlling flow rate.
We trust you will find our valves will provide the solution to all your constant flow requirements.
