Replaceable 440C Stainless
Steel Seat/Venturi | The venturi is an integral part of the removable
seat. It is readily changed in-line should different
flow characteristics be required or replacement
be necessary from excessive wear. The orifice
is sized to keep fluid velocity across the seat
below damaging levels. The exit orifice angle is
designed to minimize downstream piping erosion
and noise. Several erosion-resistant materials are
available. Consult factory. |
Position Indicator | The position indicator is easy to read and an
accurate indication of valve stem position. |
Axially-loaded Packing System | The packing is uniformly axially loaded. The
bonnet cartridge packing chamber with a secure
leakproof bonnet allows rapid access
to valve trim for ease of inspection
and maintenance. |
Mated Stem Assembly | The stem assembly is mated to the orifice for
proper control. Like the orifice seat assembly,
it is readily changeable should different flow
characteristics be required or excessive erosion
occur. |
Pressure Seal Bonnet | A secure, leakproof bonnet allows rapid
access to valve trim for inspection and
maintenance. The pressure boundary is
sealed at the smallest diameter possible
to ensure maximum sealing capability. |
Two-Year Warranty | Conval is committed to unsurpassed quality.
We are so confident of the quality of our
product, that we offer a two-year warranty. |
