Description

1 Inch High Pressure 316L Stainless Steel Solenoid Valve – Up to 300 Bar

The CNXHPI025ASS is a heavy-duty high pressure stainless steel solenoid valve engineered for demanding industrial, petrochemical and process control applications. Available in both normally closed and normally open configurations, this pressure-assisted piston valve provides reliable operation with air, water, gases, oils and industrial fluids at pressures up to 300 Bar.

Manufactured from 316L stainless steel throughout, the valve combines exceptional corrosion resistance with high flow capacity and industry-leading pressure ratings. Every valve is individually function tested, pressure tested and leak tested before dispatch and can be supplied with ATEX-certified hazardous area coils for operation in explosive atmospheres.
