VEB-4602JBCL 1/2 in. 3-Way NPT Characterized Control Valve, 4.3 Cv, Proportional Actuator with Electronic Fail-Safe
Three-way characterized ball valve with a premounted proportional actuator, piped for mixing or diverting hot or chilled water. A capacitor drives the valve to the switch-selected fail position on power loss. An optimizer insert characterizes the ball for equal percentage flow. Allow about 30 seconds after power-up before the valve moves.
Key Features
- Cv: 4.3
- Max. close-off: 50 psi
- Control signal: 0-10 or 2-10 VDC
