The PU225A Series explosion-proof solenoid valve is a 2-way, pilot-operated diaphragm valve engineered for reliable on/off control of fluids such as water, light oil, and compressed air within industrial systems. Its design ensures precise operation, making it ideal for various automation needs.
Constructed with a durable brass body, this valve is built to withstand demanding environments. It comes equipped with seals made from NBR, EPDM, or FKM materials, allowing it to handle different media types and temperature conditions effectively.
One of the key features of the PU225A Series is its explosion-proof coil enclosure. This safety measure enables safe installation in potentially hazardous locations where managing explosive atmospheres is critical.
Supporting a wide pressure range from 0.05 to 1 MPa and offering multiple port sizes ranging between 3/8" and 2", the valve delivers excellent flow capacity. Its dependable performance makes it suitable for a diverse array of automation and process control applications.
Features:
This valve features a 2-way design, available in normally closed (NC) or normally open (NO) configurations. It is a pilot-operated diaphragm type, ensuring reliable and efficient performance.
Crafted from durable brass, the valve body offers excellent corrosion resistance and ensures a long service life, making it suitable for various demanding environments.
Port sizes range from 3/8" to 2", with options for both NPT and BSP threading. This variety accommodates different flow requirements and installation needs.
The valve is available with orifice sizes of 13mm, 25mm, 38mm, and 50mm, providing flexible control over fluid flow to match specific system demands.
Operating across a wide pressure range from 0.05 to 1.0 MPa (0.5 to 10 bar), this valve is adaptable to numerous applications requiring varying pressure levels.
Standard sealing is done with NBR material, but there are options to select EPDM, FKM, or Silicone seals, allowing for chemical and temperature compatibility tailored to your needs.
The valve supports a flexible voltage supply, compatible with 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC at both 50Hz and 60Hz frequencies, ensuring easy integration into different electrical systems.
It is designed to handle media such as air, water, and light oil, making it versatile for a wide range of industrial applications.
For safety, the valve is enclosed in an explosion-proof housing, certified for use in hazardous locations where spark protection is essential.
Its compact design saves space during installation and offers multiple mounting options to fit various setups efficiently.
