Details
G350B-N+SVKX24-MFT 2 in. 3-Way Globe Valve with Electronic Fail-Safe Actuator, 24 VAC/DC, MFT
Mixes or diverts chilled or hot water, up to 60% glycol, in an ANSI Class 250 bronze body with NPT ends.
Ships set for 2-10 VDC control and feedback; ZTH US sets other VDC ranges, PWM, on/off, or floating, and a ZG-R01 500 ohm resistor allows 4-20mA.
Drives the valve to its fail-safe position on power loss after a 2 s delay; a switch reverses the fail direction.
Key Features
