Product Description:
The PU225S Series is a 2/2-way normally closed solenoid valve featuring a piston pilot-operated mechanism and a durable brass construction. It is specifically designed to provide dependable ON/OFF control for steam, hot water, compressed air, and other high-temperature fluids.
Built with a sturdy brass body and equipped with PTFE sealing material, this valve ensures outstanding leak-tight performance and exceptional durability, even in demanding steam applications up to temperatures of +185°C. Its piston pilot-operated design requires a minimum differential pressure of 0.05 MPa (0.5 Bar) to function effectively, making it an ideal choice for medium to large diameter piping systems.
The PU225S Series is available in port sizes ranging from 3/8" to 1", with orifice sizes of 13mm and 25mm. This configuration provides superior flow capacity along with a long service life, suitable for continuous-duty industrial environments. Manufactured in Ningbo, China, and bearing CE certification, this valve is recognized globally for its quality and reliability across various industries.
Features:
Piston Pilot Operated Design
The valve features a piston pilot operated design, utilizing pressure-assisted operation to guarantee reliable switching performance. It requires a minimum differential pressure of just 0.05 MPa (0.5 Bar) to function effectively.
2/2 Way Normally Closed Function
Equipped with a spring-return mechanism, this valve remains closed when de-energized. This fail-safe design ensures safety by preventing unintended fluid flow during power loss or system shutdowns.
Durable Brass Body Construction
Crafted from forged brass, the valve body offers excellent corrosion resistance and robust structural integrity, ensuring long-lasting service even in demanding environments.
PTFE Seal Material for High Temperature
The high-quality PTFE seals are capable of withstanding media temperatures up to +185°C, providing superior leak-tight performance specifically suited for steam applications.
Wide Operating Pressure and Temperature Range
This valve supports an operating pressure range from 0.05 to 1.0 MPa (0.5–10 Bar), meeting a variety of system requirements. It is also compatible with media temperatures ranging from -10°C up to +185°C, making it suitable for both steam and hot water uses.
Multiple Voltage and Port Size Options
To accommodate diverse control systems, the valve is available in several voltage options including 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC (50/60Hz). Additionally, it offers flexibility in installation with port sizes of 3/8", 1/2", 3/4", and 1" female threaded connections.
Certification and Production Capacity
The valve meets CE certification standards, ensuring compliance with international safety and quality regulations. Backed by a high production capacity of 200,000 units per month, it reliably supports bulk order demands.
