Curtiss-Wright’s Industrial Division Offers Restricted Lift Options for the Farris 2600/2600L Series Pressure Relief Valve

CHRISTCHURCH, UK–(BUSINESS WIRE)–#FarrisEngineering–Curtiss-Wright’s Industrial Division has announced that its business
unit Farris Engineering will now offer restricted lift on its 2600 and
2600L Series API-type pressure relief valves. The restricted lift option
is available on orifice sizes D-Z for compressible service for both new
2600 Series valves and as a retrofit option for Farris’ in service
valves.

ASME Code Section VIII and API 526 both provide for certification and
use of a restricted lift design for relief valves. Farris’ design option
allows operators to customize the valve lift to meet their specific
capacity requirements. ASME code requires that restriction should be not
less than 30% of the PRV’s full rated lift or less than 0.080 inches.

The benefits of using a restricted lift valve for operators is that they
can more closely match the pressure relief valve’s flow capacity to
their system’s required capacity. Restricted lift can improve a valve’s
performance and stability especially in larger orifice size valves.
Pressure relief valves with a restricted lift option are also a cost
effective solution for situations where PRV’s experience inlet pressure
losses in excess of 3% of set pressure.
