Construction
□ Compact and lightweight construction
□ Wide variety of trims with different Cv and characteris-
tics
□ Both metal and soft seats are available depending on
the application
□ Optional bellows seal for toxic or other applications
where no stem seal leakage is allowed
□ Wide material selection for different applications
□ Many end connection styles available for different
applications
□ Extension bonnet design for wide temperature range
Quick change, general contoured plug offers a smooth flow pro- The trim design presented a multi-hole trim. There is Tendril 1
file. The trim is most suited to low pressure drop application and design in standard depending on pressure drop and
is used in the majority of control applications. potential for cavitation.
The pressure drop is divided by multi-holes so that the pressure
progressively reduces as it passes through the trim. This gives
excellent resistance to cavitation on high pressure drop applica-
tions.
