Product - Butterfly Valves NE/NF & NP/NT Series

​​​​​​​​​High performance solutions​

Our Butterfly Valves NE/NF and NP/NT series have excellent perfomance, easy maintenance and component interchangeability that provides reliability and serviceability.

Key Features

  • Monobloc body

  • Seat with rigid ring

  • Split shaft with low pressure drop

  • Wide range of materials​


  • ​Body
    Wafer, lug or flange style monobloc body has been designed to ensure maximum security and reliability (proven by Finite Elements Analysis). It has an extended valve neck enabling piping isolation. The wafer-style body has in its external diameter a shaped ring that eases valve installation and centralization in the pipe flanges.

  • ​Disc
    Disc has been designed to minimise pressure drop in totally open position. Sealing area is polished in the entire perimeter providing total sealing in relation to the seat and ensuring low operating torque

NE/NP: 1½” to 12”  
NF/NT: 14” to 24”

NE/NF: 50 to 250 psi 
NP/NT 100 to 150 psi

  • Shaft
    The upper shaft transmits the rotation movement to the disc by means of square drive, so, there is a system that eliminates the existence of taper pins, keys and studs removing the possibility of wear and leakage by these parts. The upper shaft is fixed to the body through a spring pin, defining the “anti-extrusion” system, avoiding the shaft being extruded from the body. The lower shaft is fixed to the body through a spring pin, defining the “Trunnion” system of the set, ensuring perfect alignment between body, disc and shaft

  • ​Actuation
    Allows the coupling of manual, pneumatic and electric actuators directly on the top flange that, together with the shaft complies with ISO 5211 Standard.​
