    • PN10/16/PN25 Resilient Seated Gate Valve is operating by the EPDM covered iron wedge moving perpendicular to the flow axis through a worm machined stem multi turned
    • 100% tight sealing is achieved through EPDM covered wedge fully contacting. The fusion bonded epoxy coated flow surface
    • In each time the valve is opened, the flow on the line cleans the sealing surface. Prevents from dirt and deposits
    • With its short installation length ( DIN 3202 F4), does not occupy a big place
    • It has ductile iron body and stainless steel stem
    • Inner and outer surfaces are coated with minimum 250 microns fusion bonded epoxy
    • Suitable to install actuator and gearbox
    • Suitable to use with ground and underground applications. Can be operated with extension spindle
    • Very low head loss rating. Can be operated with lower torque ratings, no maintenance needed

    Hot Water, Cold Water, Fluids without acidity or alkalinity properties
