Masoneilan 35002 Series Camflex™ Rotary Control Valve

  • Description:

    Over one million 35002 Series Camflex valves have been successfully installed in a variety of process applications. Today's Camflex II continues to provide legendary dependability through a field-proven concept that remains the standard of excellence for all eccentric plug rotary control  valves. The standard version includes the EF Seal (Emission Free pocking) with emissions rated at less than 500 ppm up to 75000 cycles. 

    Complete line of eccentric plug control valves effectively combining enhanced control performance, simplicity and long-term reliability for a broad range of applications.

    The Camflex II valve is a heavy-duty, automatic-throttling control valve that incorporates the following features:

    • The flangeless body rating is a rugged ANSI Class 600.
    • Heavy-duty guide lugs assure quick, positive alignment during installation.
    • The flanged version is available in 1 in. through 12 in. (25 mm through 300 mm) sizes in 150 or 300 ANSI and 1 in. through 8 in. (25 mm through 200 mm) in 600 ANSI.
    • The optional Camflex GR (Globe Replacement) version is available in 1 in through 6 in. sizes (25mm through 150mm) in ANSI Class 150, 300, and 600 ratings and allows direct replacement of conventional reciprocating globe valves.
    • Standard integral extension bonnet allows for a wide range of fluid temperature applications (-320˚F to 750˚F), (-196˚C to 400˚C).
    • The unique self-aligning eccentric rotating plug provides tight shutoff and low dynamic forces.
    • An optional patented differential velocity device (DVD) separates compressible flowstreams into a high velocity core and a low velocity envelope flowstream. This provides up to 18 dBA noise attenuation.
