ZDLP Electronic Single-Seat Control Valve

● Product Overview of "Electronic Electric Single Seat Control Valve"

ZDLP(M) electronic electric single seat control valve consists of a low flow resistance straight-through single seat or low flow resistance sleeve valve paired with a German imported PSL series linear electric actuator (domestic 3810 or 3410 series actuators can also be selected). The electric actuator includes a built-in servo amplifier, eliminating the need for an external servo amplifier. It operates by inputting a control signal (4-20mA DC or 1-5V DC) and a single-phase power supply, enabling regulation of parameters such as pressure, flow, temperature, and liquid level.

● Product Features of "Electronic Electric Single Seat Control Valve"

The ZDLP(M) electronic electric single seat control valve features compact size, lightweight, high flow capacity, simple wiring, and high regulation accuracy. It is widely used in industrial automation control systems across industries such as power, petroleum, chemical, metallurgy, environmental protection, education, and scientific research equipment.
