Fisher HP Series control valves are single-port,
high-pressure, globe- or angle-style valves with metal
seats, cage guides, and push-down-to-close valve plug
action.
These valves are designed for high-pressure
applications in process control industries such as
power generation, hydrocarbon production, chemical
processing, and refining.
HP Series valves are designed with corrosion
allowance; NACE compliant materials are available.
Extra valve body wall thickness provides a safety
margin of protection against erosion, as well as extra
protection against corrosion due to chemical attack.
Because these valves feature a thicker valve body wall,
they are available in higher intermediate ratings with
weld-end fittings.

These valves use a balanced valve plug with graphite
piston rings and are well suited for general applications
with process temperatures in excess of 232_C (450_F),
where extremely tight shutoff is not required.

These valves use a balanced valve plug and offer
excellent shutoff with process temperatures below
232_C (450_F). The temperature limits of HPT can be
extended above 232_C (450_F) to 316_C (600_F) by
using PEEK (PolyEtherEtherKetone) anti-extrusion rings
in combination with a spring-loaded PTFE seal. The
PEEK anti-extrusion rings expand to help close off the
clearance gaps on the plug outside diameter and the
cage inside diameter where the PTFE seal may extrude
at high temperatures and pressures.
