Two-Way & Three-Way Electronic Globe Valves
1/2″ to 6″, Two-State, Tri-State, Modulating
DESCRIPTION
Clarksol is offering Globe Valves 1/2″ through 2″ are bronze body, NPT screw type, and are rated for ANSI Class 250 working pressure. The operating temperature range (of the controlled medium) limits are 20° to 250°F. Valve stems are stainless steel and valve plugs are brass for water service and brass or stainless steel for steam service, depending on temperature and pressure requirements. Stem packing is EPDM O-ring or Teflon/EPDM, depending on temperature. 1/2″ through 2″ two-way valves are rated for 25 PSI differential for water applications and 15 PSI inlet for steam applications. 1/2″through 2″ three-way valves are rated for 25 PSI differential. Optional trim materials are available for higher temperature/pressure applications. Flow type for two-way valves is equal percentage or modified equal percentage for water or steam applications. Flow type for three-way valves is linear and all screwed valves meet ANSI class IV leakage standards (not to exceed 0.01%of Cv).
Globe Valves 2-1/2″ through 6″ are cast iron body, flanged, and rated for ANSI Class 125 working pressure. The operating temperature range (of the controlled medium) is 20° to 250°F for water and/or low pressure steam applications (up to 15 PSI inlet pressure) with normal duty packing and up to 337°F maximum temperature with optional Teflon/EPDM V-ring packing for higher pressure steam and hot water. Valve stems are stainless steel and valve plugs are brass or stainless steel. Stem packing is EPDM O-rings or optional Teflon/V-ring/EPDM O-ring. Two-way standard valves are rated for 25 PSI differential pressure for water applications and 15 PSI differential pressure for steam applications (50 PSI differential with optional stem packing and stainless steel trim). Three-way valves are rated for 25 PSI differential (optional trim for 50 PSI differential). Flow type for two-way valves are the equal percentage or modified equal percentage for water applications. Flow type for three-way valves is modified equal percentage or linear. All flanged valves meet ANSI Class IV leakage standards (not to exceed 0.01%of Cv).
Available actuators are modulating, floating (tri-state), or two-position type with or without spring return as required for the application. Each valve actuator has current limiting or stalls detection circuitry incorporated into its design to prevent damage to the actuator. A gear release or manual override crank is provided on the motor to allow for manual override. The actuators are powered by a 24 VAC,120 VAC or 24 VDC power source. Actuators are UL listed.
