A Direct Acting Solenoid Valve is a compact, fast-responding valve designed for precise on/off flow control in low-pressure pneumatic, gas, and liquid systems. Unlike pilot-operated valves, direct acting valves do not require a minimum pressure differential to operate. They use electromagnetic force alone to lift or close the plunger against the seat, making them ideal for low flow, low pressure, and start/stop operations.

Typically offered in 2/2-way (on/off) or 3/2-way (diverting/exhausting) designs, these valves are available in Normally Closed (NC) or Normally Open (NO) configurations. They are widely used for controlling air, water, inert gases, vacuum, and light oil circuits in applications where precise control, quick actuation, and zero pressure start are crucial.

Manufactured with robust brass, stainless steel, or anodized aluminum bodies, and sealed using high-quality NBR, EPDM, or Viton, the valves offer long service life and excellent resistance to corrosion, temperature, and chemical exposure. The electrical coils are available in a wide range of voltages (12V, 24V DC, 110V, 220V AC) and offer quick response times.

Direct acting solenoid valves are ideal for pilot valve control, laboratory equipment, analytical systems, dispensing systems, and precision fluid dosing.
