Product Description:
PU220 Series – Direct Acting Brass Solenoid Valve
The PU220 Series offers a 2/2-way normally closed direct-acting solenoid valve designed to provide dependable ON/OFF control for various neutral fluids such as water, air, and light oil. It features a strong brass body combined with a spring-return mechanism, allowing it to function efficiently even at zero pressure differential. This makes it particularly suitable for applications where immediate response is required under low-pressure conditions.
Thanks to its compact and lightweight design, the valve is easy to install within environments where space is limited. The PU220 is available with a variety of port sizes ranging from 1/8" to 1", and orifice sizes between 1.5mm and 25mm. This flexibility ensures consistent and precise media control with minimal leakage, making it a reliable choice across a broad spectrum of industrial uses.
PU225 Series – Pilot Operated Brass Solenoid Valve
The PU225 Series is a 2/2-way normally closed pilot-operated solenoid valve engineered for high-flow applications involving water, air, and light oil. It incorporates a pressure-assisted piston design that requires a minimum differential pressure of 0.05 MPa (0.5 Bar) for operation, making the valve especially effective for large-diameter piping systems.
Constructed with a robust brass body and equipped with seals made from NBR, Viton, or EPDM, the PU225 provides exceptional flow capacity and durability in demanding industrial settings. It is available in port sizes ranging from 3/8" to 2" and orifice sizes up to 50mm, delivering superior CV values to ensure maximum throughput during continuous-duty use.
Features:
PU220 Series – Direct Acting
The PU220 series features a direct acting operation with a spring-return mechanism, enabling it to function from zero pressure differential (0 MPa). This design ensures prompt and reliable performance right from startup without requiring any initial pressure.
Designed for compactness and lightweight installation, the PU220 boasts a small physical footprint, making it ideal for use in confined or tight spaces where installation room is limited. Its durable forged brass body provides excellent corrosion resistance as well as structural strength, ensuring long-lasting durability.
Customers can choose from multiple seal options, including standard NBR seals, and optional FKM (Viton) or EPDM seals, catering to a wide range of media compatibilities. The series offers a broad orifice size range from 1.5mm up to 25mm, allowing users to select the optimal size for various flow requirements.
The coil supports a wide variety of voltage options such as AC220V, AC110V, AC24V, DC24V, DC12V, among others, enhancing its versatility across different applications. It is equipped with Class B coil insulation to guarantee reliable operation and excellent thermal durability.
With an IP65 rated enclosure, the coil is both waterproof and dustproof, making the PU220 suitable for harsh environmental conditions. Additionally, it supports a 100% duty cycle, enabling continuous operation without the risk of overheating.
PU225 Series – Pilot Operated
The PU225 series utilizes a pilot-operated, pressure-assisted design that requires a minimum differential pressure of 0.05 MPa (0.5 Bar) for reliable activation. This makes it particularly suited for high-flow and large-diameter applications where maintaining steady pressure is essential.
This series provides large orifice sizes up to 50mm, which deliver exceptional flow capacity (CV values up to 48), allowing for maximum throughput in demanding systems. Constructed with a durable brass body, the PU225 ensures excellent mechanical strength and resists corrosion effectively.
Multiple seal options including NBR, FKM (Viton), and EPDM are available, providing flexibility to handle various media types. The operating pressure range spans from 0.05 to 1.0 MPa (0.5 to 10 Bar), accommodating a broad spectrum of process requirements.
The PU225 offers a wide port size range from 3/8" up to 2", facilitating easy integration within diverse system configurations. Its coil enclosure is IP65 rated, providing waterproof and dustproof protection for enhanced reliability in challenging environments.
Specifically designed for horizontal mounting, this series ensures optimal performance when installed in the correct orientation. Like the PU220, it supports a 100% duty cycle, making it suitable for continuous operation without overheating concerns.
