STEAM / CONDENSATE SYSTEMS VALVES

When the operating pressure is 80 psi and above, the system shall be considered high pressure. Where operating pressures is between 15 – 79 psi, the system shall be considered medium pressure. When the operating pressure is below 15 psi, the system shall be considered low pressure. In order to improve standardization and quality, steam/condensate system valves, operating in the medium and low pressure class, shall utilize the same type of valves per the following size/application schedule:

Size Range	Application	Operating Pressure	Valve Type
¼” – 2”	Steam/Condensate	80 psi & above	A1
¼” – 2”	Steam/Condensate	Below 80 psi	A2
2 ½” – 8”	Steam/Condensate	80 psi & above	B1
2 ½” – 8”	Steam/Condensate	Below 80 psi	B2
10” & up	Steam/Condensate	80 psi & above	C1
10” & up	Steam/Condensate	Below 80 psi	C2
¼” – 3”	Domestic Hot/Cold Water	125 psi & above	D1
¼” – 3”	Domestic Hot/Cold Water	Below 125 psi	D2
4” & up	Domestic Hot/Cold Water	125 psi & above	E1
4” & up	Domestic Hot/Cold Water	Below 125 psi	E2
¼” – 3”	Chilled Water	Below 125 psi	D2
4” – 10”	Chilled Water	Below 125 psi	E2
12” & up	Chilled Water	Below 125 psi	F1
¼” –  3”	Condenser Water	Below 125 psi	D2
4” & up	Condenser Water	Below 125 psi	F1
