PN 40 flanged ball valve is operating by a ball having a hole with the same size as the flow section, through the help of the stem, rotating quarter turn (90 degree) between teflon seats where the ball to be parallel or perpendicular to the flow axis.
Can be installed bidirectional.
Through the stainless steel belleville spring reinforced teflon (PTFE) seats, 100% tight sealing is achieved in lowest and highest pressure ratings.
Can be installed directly to the pump without any need for additional intermediary parts.
The compatibilty of teflon material with various flow types and its resistance to higher temperatures enables it to be used in wide range of applications.
It is appropriate to be used in fully open or fully closed position.
In fully open position, since there is no reduction in flow section, the head loss is nearly zero.
