company of solenoid valves and system solutions inside field of CNG completing stations with pressure ranges approximately 350 bar, has formally introduced the following generation of 1″ CNG valves pertaining to truck filling. The company says that with regards to the older generation of valves it has been able to increase the flow rate of the 1″ valve (type 3054, orifice dimensions DN 18) by TWENTY %, which leads to your flow rate of Kv valuation 7. 5 m3/h or Cv 8. 7 usgal/min.
In 2014 the fresh valve generation ProValve One was introduced with orifices involving 8 (type 3051) and 12 mm (type 3052). Now in 2015 the new generation for orifice 18 (type 3054) is following.
Eugen Seitz AG is active in the US-market, where there may be a demand for the excessive flow rates and fast filling times needed in view of truck filling. Therefore in 2014/2015 we designed a different 1″ valve (type 3054) to receive the highest flow fee possible. This valve has been released successfully on to the market in the interim.
According to the website article, the Kv / Cv values used nowadays are not precise affected person compressed real gases. As an alternative to the water-based Kv-values, Seitz prefers a mass flow model with all the parameters C and b as outlined by ISO 6358 which enables a better comparison between the actual physical behaviours of compressed unwanted gas at different pressures. “We have the ability to calculate these values by means of simulation, but also measure these parameters in the new test bench by using different pressures. ”.
