Tight butterfly valves type PRS are used as control elements in automatic control and remote control systems. They are designed to control the flow rate of liquid and gases.
full shut of tightness up to 2 MPa pressure drop
seal insert is strengthened by aluminum framework andcan be use up to nominal pressure PN20 (ANSI 150)
wide material range of seal inserts give possibility to optimize adaptation type of butterfly valve to type of medium
