DELCO Valve 3 Way Mixing Diverting Electric Control Valves
The electric 3-way control valve is composed of three ZDLQ/X 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.
Model: ZDLQ/X
Size Range: 1/2” to 12”
Pressure Range: 1.6 to 6.4 MPa
Material: Stainless Steel 304/316, WCB
DELCO Cast Steel Electric Actuator Globe Control Valve Introduction:
The 3-way electric control valve offers two action types: electric mixing (converging) control valve and electric diverting (diverging) control valve. This valve system comprises the PSL series and 3810 series linear electric actuators, combined with a 3-way valve body. The electric actuator features an integrated electronic structure with a built-in servo amplifier. By receiving input control signals (4-20mADC or 1-5VDC) and power supply, it controls the valve opening to regulate parameters such as pressure, flow, liquid level, and temperature.
The electric 3-way mixing control valve is primarily utilized for blending two fluids into a third fluid, while the 3-way diverging electric control valve is mainly employed for splitting one fluid into two separate fluids.
