Anonymous Poster	Parameters of Gas Regulators (Pilot Operated) 08/18/2010 3:40 AM
	Hi there, Can anybody tell me what SZ (lock up pressure zone class) means? It is not the same as SG (closing pressure category)... Thanks 4 your help! Trigon

	SG is spherical-graphite (body material} like CI cast iron/MI malleable iron. __________________ I not only use all the brains that I have, but all that I can borrow. Woodrow Wilson

	Sorry, these parameters are process properties of gas regulators: SG = Lock up pressure (the pressure at the downstream side when the customer shuts off. SZ = The flow range where the AC remains the declared one. Thanks anyway,
