Siemens 275-05921 Flowrite 599 3" 2-Way Flanged Globe Valve, NO, 24V Floating, ANSI 250

The Siemens Building Technologies 275-05921 is a Flowrite 599 Series 3-inch, 2-way flanged globe control valve assembly. It has a 24 Vac floating (3-position), non-spring return electro-mechanical actuator. It is a normally open valve with stainless steel trim and is rated ANSI Class 250. It suits HVAC water, glycol and steam control applications and is also known as a 3" actuated globe valve or motorized control valve assembly.

Key Features:

• Flow: 100 Cv with an equal percentage flow characteristic
• Action: Normally open (NO)
• Body and trim: Cast iron ASTM A126 Class B body with stainless steel trim. Stem is stainless steel ASTM A582 Type 303, with a single metal-to-metal seat and EPDM O-ring packing.
• Body rating: ANSI Class 250
• Stroke: 3/4 inch (20 mm)
• Leakage: ANSI Class IV (0.01% of Cv), with rangeability of 100:1 or better
• Medium temperature: 20 to 250 °F
• Actuator: SKD82.50U, 24 Vac 50/60 Hz, 3-position floating control, non-spring return (fail-in-place), 13 VA, NEMA 1
• Rated close-off: 25 psi
• Components: Assembled from Flowrite valve body 599-05921 and actuator SKD82.50U

This factory-assembled valve and actuator package has a direct-coupled universal bonnet. That makes it a straightforward way to add modulating, floating-point control of water, glycol or steam in building automation systems.
