COVNA 3 Way Mixing Diverting Electric Globe Control Valve
3 way electric control valve has two action types: electric mixing(converging) control valve and electric diverting(diverging) control valve.The 3 way electric control valve is composed of PSL series and 3810 series linear electric actuator and 3-way valve body.The electric actuator is an electronic integrated structure with a servo amplifier. The input control signal (4-20mADC or 1-5VDC) and the power supply can control the valve opening to achieve to control the parameters of pressure, flow, liquid level and temperature. The electric 3-way mixing control valve is mainly used for mixing two fluids into a third fluid; the 3 way diverging electric control valve is mainly used for dividing one fluid into two fluids.
- Model: Electric control valve
- Size Range: 1'' to 12''
- Pressure Range: 1.6 to 6.4MPa
- Material: Stainless Steel, WCB
COVNA Cast Steel Electric Actuator Globe Control Valve Overview:
The electric 3-way control valve is composed of three 3610L series electric actuators and a three-way control mechanism. Electric actuator in a servo system, no need of a servo amplifier, have spread into the signal and power source control operation, simple wiring. Adjusting mechanism is combined and split two ways, can replace the two-valve and a three-way pipe has been widely used in some occasions. Two commonly used in the heat exchangers and regulation of simple ratio regulation.
