EH Series Valves

These valves are specially designed for high-pressure

applications. Fisher EH valve configurations

incorporate proven techniques in flow-stream

contouring for higher capacities and in valve trim

design for reliability in severe applications.

The temperature limits of EHT valves can be extended

above 232_C (450_F) by using PEEK

(PolyEtherEtherKetone) anti-extrusion rings in

combination with a spring-loaded PTFE seal. The PEEK

anti-extrusion rings expand to close off the clearance

gap between the plug and the cage where the PTFE

seal may extrude at high temperatures and pressures.

The temperature limits are extended to 316_C (600_F)

for non-oxidizing service and to 260_C (500_F) for

oxidizing service.

NACE MR0175-2002. Contact your Emerson Process

Management sales office. for information on NACE

MR0175/ISO 15156 or NACE MR0103.

Features

n Improved Cage Design—Drilled-hole cages, offering

excellent strength and additional resistance to

destructive vibration, are standard. Special

materials of construction are readily available.

n O-ring Seat Ring Gasket Construction—Use of O-ring

construction provides excellent shut-off with

minimal seat ring installation torques for

temperatures up to 232_C (450_F). O-ring
