The PU220 Series is a 2/2-way normally closed solenoid valve that operates directly, providing dependable ON/OFF control for a variety of neutral fluids such as water, air, and light oil. It features a sturdy brass body combined with a spring-return mechanism, allowing it to function effectively even at zero pressure differential. This characteristic makes it particularly suitable for applications that demand immediate response under low-pressure conditions.
Its compact and lightweight design ensures effortless installation, especially in environments where space is limited. The valve is available with port sizes ranging from 1/8" to 1" and orifice sizes between 1.5mm and 25mm. The PU220 Series guarantees reliable performance with minimal leakage, providing accurate media control across a broad spectrum of industrial uses.
PU225 Series – Pilot Operated Brass Solenoid Valve
The PU225 Series consists of 2/2-way normally closed solenoid valves that are pilot-operated, specifically crafted to handle high-flow applications involving water, air, and light oil. It incorporates a pressure-assisted piston design which necessitates a minimum differential pressure of 0.05 MPa (0.5 Bar) to function correctly. This makes the PU225 highly effective in large-diameter piping systems.
Built with a robust brass body and equipped with seals made from NBR, Viton, or EPDM, the valve ensures excellent flow capacity and durability even in challenging industrial environments. With port sizes available from 3/8" to 2" and orifice sizes up to 50mm, the PU225 Series offers exceptional CV values, enabling maximum throughput during continuous-duty operations.
