2W Series Brass Solenoid Valve With Manual Control Operation Manual Override

The 2W Series Brass Solenoid Valve with Manual Override is a versatile, direct-acting / semi-direct lift diaphragm solenoid valve designed for reliable control of water, air, gas, and low-viscosity fluids.

Featuring a rugged forged brass body and a high-performance electromagnetic coil, this model integrates a mechanical manual override switch (brass knob). This critical feature allows operators to open or close the valve manually during power outages, system testing, or emergency commissioning, ensuring uninterrupted system control and enhanced safety.

Key Features

Manual Override Function: Equipped with a durable brass manual knob. Enables manual mechanical control of the valve when electric power is unavailable or during maintenance.
Premium Forged Brass Body: High-density, corrosion-resistant brass body prevents leakage and ensures a long service life in demanding industrial or commercial environments.
Reliable Diaphragm Design: Utilizes high-quality elastomeric seals (NBR/EPDM/Viton options) for bubble-tight sealing and smooth zero-differential pressure startup.
Heavy-Duty Encapsulated Coil: IP65-rated moisture-proof and dust-proof coil with flying leads ensures stable electrical performance and thermal dissipation.
Bidirectional Installation Friendly: Clear directional flow arrow cast into the valve body prevents installation errors.
