If the valve nameplate shows an ASME

pressure-temperature class, maximum inlet pressure

and temperature is consistent with applicable ASME

class per ASME B16.34.

If the nameplate does not show an ASME class, it will

show a maximum cold working pressure at 38_C

(100_F) (for example, 3600, 6000, 9000, or 10,000

psi)

Maximum Allowable Pressure Drops

(1)

Flow up: Capable of full rated pressure drops

Flow down: See table 2 for pressure drop limits for

ceramic trim

Shutoff Classification Per ANSI/FCI 70-2

and IEC 60534-4

Standard: Class IV

Optional: Class V

Maximum Service Temperature

232_C(450_F)

Flow Characteristic

Equal Percentage

Flow Direction

DValve:Flow up through t he seat ring and out past

the valve plug

DA Valve: Flow in either direction

Approximate Weight

DValve:34 kg (75 lbs)

DA Valve: 46 kg (100 lbs)
