Constant Flow Valve Water

Maric flow control valves maintain a fixed pre set constant flow rate regardless of pressure.

Constant flow valve water.

Mathematically the flow coefficient c v or flow capacity rating of valve can be expressed as. These valves have no electronics. Akro water saving valves maintain a fixed constant flow rate and are used in many hotels and homes to save water and money. Flow control valves are simple with no external actuation.

The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. This means a constant flow rate irrespective of fluctuating pressures upstream or downstream of the valve. Flow control valves maintain a fixed pre set constant flow rate regardless of pressure. Bt maric constant flow valves.

They are fitted with the high performance maric flow control rubber. A constant flow rate even while demand for water or upstream or downstream pressures are changing can offer valuable protection for flow rate sensitive equipment and water distribution systems. The valve mechanically senses down stream pressure and a pilot valve or spring mechanically controls the valves position. Bertfelt is the leading manufacturer of bt maric constant flow valves for industrial use.

As the uk government and building standards recommends 6 litres per minute for hand washing and 9 litres per minute for showers these valves are a perfect retro fit to washbasins kitchen taps. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. They are self regulating self cleaning tamper proof long life 15 years and reliable.
