ZCZTH Double coil self holding solenoid valveDetailed product description：

ZCZTH dual coil self holding solenoid valve features:

Pulse holding energy-saving and power-saving dual line operation with an ultra long lifespan
Three dimensional sealing to prevent leakage and guide device to eliminate faults
Multiple functions to choose from, instant response performance stable

Application scope:
Intelligent self-control systems for aerospace, military, nuclear, shipbuilding, petrochemicals, electricity, energy, urban heating, steam supply, water supply, and other industries.

Working Principle:
Adopting self-locking and self holding, dual ring stainless and corrosion-resistant steel three-dimensional sealed piston structure, dual coil control, one coil controls on and the other coil controls off, only a pulse signal is given to the coil, and instantaneous power can be applied to maintain the working state, with low energy consumption (low power and instantaneous power), sufficient flow rate, and long service life.
